1st Gen Bolt-On Upgrade List & Other Modifications + DIY Help

Welcome to the 1st gen registry for all direct bolt-ons and other various modifications that are possible on our cars! Here, all of these improvements will be documented as well as any DIYs I and others have written and more. This post will consistently be updated with new info on a regular basis. Fitment info is confirmed with real-world field testing experience on 01-03 (My 02 Highlander), 04-07 ('08 RX350) and 08-19 if possible ('14 RX350).

Comparison between Gen 2 and Gen 1 rear struts on an AWD HiHy (225/65R17 tires)



Gen 2 strut & springs up front. Gen 2 struts & Gen 1 springs out back on 01-03 AWD


Frame (excl hybrid):
Front subframe [2001-2013 Highlander, 2004-2015 RX]
Rear subframe AWD [2001-2013 Highlander, 1999-2009 RX]
Front subframe [2009-2015 Venza] (Looks similar to 2001-2013 Highlander)
Rear subframe FWD [2001-2013 Highlander, 2009-2015 Venza, 2002-2011 Camry, 2005-2012 Avalon, 2004-2008 Solara, 2004-2009 RX)
Front subframe [2014-2019 Highlander] (Slightly beefier design. Similar to 2001-2013 frame)
Front subframe [2004-2020 Sienna AWD] (Looks similar to the Highlander one)
Front subframe [2016-2022 RX] (Beefier. Doesn't have the space to mount the rear engine mount bracket, uses bigger sway bar brackets)
Rear subframe AWD / FWD [2014-2023 Highlander, 2010-2022 RX] (Designed for the double wishbone suspension of the newer models)
Rear subframe AWD [2009-2015 Venza] (Differential bushing is different and is in the wrong spot)


Suspension:
Lowering springs [1999-2003 RX] (1-1.5" drop, front spring is shorter than stock, likely due to the RX300 having a different spring perch)
Lowering springs [2004-2009 RX] (1-1.5" drop, may be ever so slightly stiffer due to the 2nd gen RX weighing a little more)
Lifting springs [2001-2007 Kluger] (1" lift)

Eibach (on 08 RX): More OEM type of ride, but still offers 1.2" of lowering and stiffens up suspension nicely
H&R (on Highlander): Very firm and stiff compared to stock, lowers by ~2", springs coil tightly near top of strut

Eibach is the more sensible DD choice, but the H&R provide a lot more fun even though you sacrifice more comfort for a marginal cornering gain over the Eibachs. I'll add my thoughts on coilovers here once I get some.



Note: To maintain your alignment, you should use the 1st gen strut mounts, everything else can be taken from a 2nd gen
Rear Struts [2008-2009 RX350 AWD / FWD] (Likely identical to 04-07 struts except for the 19mm mounting holes for the knuckle instead of 17mm, which allows for more camber adjustment, specs are the same as 04-07 according to KYB)
Rear Struts [2006-2007 RX400h & Highlander Hybrid] (Similar to 04-07 struts, except the strut body length has been extended by 0.4", the stroke length has also been reduced by 0.4". Spring perch is in the same place)
Rear Struts [2008 RX400h] (Likely identical to the 06-07 RX400h strut, except it has the 19mm holes like the newer 08-09 RX350 ones)
Front springs [2008-2009 Highlander] (Stiffer than stock, ~0.5" lift)
Rear springs [2008-2013 Highlander] (Stiffer than stock, ~2" lift)
Front Struts [2008-2009 Highlander] (Higher spring perch, provides ~0.5" lift)
Front Struts [2010-2013 Highlander] (Higher spring perch, provides ~0.5" lift, option for Bilstein B6, YOU MUST USE 2010-2013 springs & lower isolators with these for the front passenger strut!)
Front Struts [2014-2019 Highlander] (Option for Bilstein B6, test fitment on RX300, fits like 2nd gen strut but with more anti-dive built-in)
Rear Struts [2008-2013 Highlander] (Higher spring perch, provides ~1" lift - option for Bilstein B6, 2004+ end links recommended if 2001-2003 AWD model. DOES NOT FIT 01-07 FWD)
Front Struts [2009-2015 Venza] (Similar to 2008-2009 2nd gen Highlander, except more stroke length and no internal rebound spring)
Front Springs [2009-2015 Venza] (Similar to 08-09 springs, appear to have a slightly stiffer rate, can be bought on Rockauto)
Rear Springs [2009-2015 Venza] (Similar to 08-13 springs, appear to have a slightly stiffer rate, can be bought on Rockauto)
Rear knuckle bushing [1999-2009 RX, 2001-2013 Highlander, 2009-2015 Venza, 1992-2018 Camry]
Rear knuckle AWD [2008-2013 Highlander, 2009-2015 Venza] (Direct fit 04-07, will fit 01-03 with the use of 04-07 rear control arms, ABS senors & rear CV axles if AWD, allows for more camber adjustment due to using our 19mm front strut-to-knuckle bolts)
Front knuckle [2008-2019 Highlander, 2011-2020 Sienna AWD, 2010-2015 RX] (You will need 2011-2014 Dodge Charger inner tie rods & 2nd gen outer tie rods. You will also need 2nd gen brake dust shields, CV axle deflector plates and wheel bearings, make sure hub has right amount of splines)
Front knuckle [2016-2022 RX] (You will need the Charger inners and 4th gen RX outers at the minimum, the stock ball joint will fit but the ABS sensor may needs modification/swapping, no confirmation on CV axle fitment. Uses bolt-in wheel bearing / hub assembly)
Front knuckle [2009-2015 Venza] (Similar to a 2nd gen knuckle, reuses every part except for the wheel bearing and CV axle deflector which is shared with the 01-07 models, Venza stock hub for FWD use only)
Rear sway bar bushings FWD [See 2001-2003 & 2004-2007 categories]
16mm rear sway bar bushings AWD [2001-2007 Highlander, 2009-2015 Venza, 2002-2006 Camry, 2004-2009 RX (Some models)]
Rear sway bar brackets AWD [2001-2013 Highlander, 2009-2015 Venza (Driver's side needs modification to fit), 1999-2009 RX]
23mm front sway bar bushings [2001-2007 Highlander, 2004-2009 RX] (2004-2009 models have updated design with teflon inner coating, this is the preferred part)
Upgraded front sway bar upper brackets [2008-2019 Highlander, 2004-2020 Sienna AWD, 2008-2009 RX400h, 2010-2015 RX350/450h]
Coilovers [1999-2003 RX300] (Front mount and adjust not compatible)
Coilovers [2004-2009 RX] (Best fitment for our cars, 01-03 needs to drill out rear strut mount to M10)
Coilovers [2002-2017 Camry, 2002-2017 ES] (Can fit FWD models, not recc)
Front sway bar end link [2004-2010 Sienna] (14mm thick end link for stock 23mm sway bar)
Front sway bar end link [2018+ Camry] (Alloy substitute link for stock 23mm sway bar)
Aluminum rear sway bar end link [See 2001-2007 FWD & AWD categories]
Front sway bar end link [2007-2017 Camry, 2010-2019 ES350] (Required if you want to run a 2nd/3rd gen front sway bar without rubbing of the end link on the strut, fitment is absolutely perfect. Sway bar end link angle will not sit parallel to the body, but it is identical to that of the respective Camry the part originates from, it is by design)
Front sway bar end link [2007-2009 ES350] (Resembles the above end link, but has a thicker 14mm body vs. 10mm)
26mm front sway bar bushings [2008-2019 Highlander, 2004-2020 Sienna AWD, 2010-2015 RX]
26mm front sway bar bushings [2004-2020 Sienna FWD, 2007-2018 ES] (Bushing does not require "clipping" to fit into the stock lower brackets)
26mm front sway bar [2008-2019 Highlander (non-hybrid), 2010-2015 RX (non-hybrid)] (DOES NOT FIT HYBRID, MAKE SURE TO BUY RIGHT VERSION DEPENDING ON IF YOU ARE FWD OR AWD - AWD bar will work on either FWD or AWD. Hybrid cars after '07 come with FWD bars as indicated by the ORANGE stripe on driver's side, you want a WHITE stripe for AWD!! The FWD/Hybrid bar will contact the transfer case on AWD models!!)
28.5mm front sway bar [2016-2022 RX] (Brackets & bushings are unique to the 16-22 RX, the spacing & size is larger and different so major modification is likely required. Bolts are M10 vs M8)
29mm front sway bar [2020- Highlander] (Subframe has been too drastically changed, the bar cannot fit)
Front sway bar brackets [2009-2015 Venza] (These brackets were designed for the Venza's subframe, therefore they are too tall as a result)

90105-107010 (15mm "Type C" 2-dot bolt - I run this on the front and back of my RX and Highlander to give me a little more negative camber adjustment)
90105-107011 (14mm "Type D" 3-dot bolt - Tried these and the camber adjustment is a little excessive)

Steering:
Steering rack [2004-2007 Highlander - Non HiHy, 2004-2009 RX330/350 - Non 400h] (16:1 ratio, 3 turns to lock. Provides a smooth, supple and isolated feel to the car's steering. These racks are made by JTEKT and are more comfort-oriented than the 01-03 racks, but they are significantly more expensive for some reason. I found this rack a lot less enjoyable to drive with)
Steering boot & Clip [2004-2007 Highlander, 2004-2009 RX] (Longer than 01-03 boot for more flexibility? It also has a larger ID by 2mm to fit the 2mm larger 04-07 rack. Can fit 01-03 rack perfectly fine)
Steering rack [2001-2003 Highlander] (16:1 ratio, 3 turns to lock. Provides a more raw, weighted steering feel to the car which I prefer. These racks are made by Koyo and have more road feel/feedback compared to 04-07 racks as well as being cheaper. These racks can directly fit 04-07 without any modifications, as I found on my RX350)
Steering boot & Clip [2001-2003 Highlander] (Shorter and firmer boot, it'll fit an 04-07 rack but you might need a heat gun to get it on, otherwise it'll fit alright and is long enough to compensate for the longer 04-07 ITRs)
Steering rack bushings [2005-2015 Tacoma] (Replacement poly bushings offered by Nolathane and Energy Suspension will fit 01-07 steering racks and cut out some of the dead zone while steering)
Outer tie rod [2004-2011 Camry] (Same length as an 01-03 tie rod, but has the more modern 04+ taper to fit 04-07 front knuckles, confirmed fitmet with stock inner tie rods on HL FB group)


FWD:
Ultra Racing UR-AR19-030 19mm rear sway bar [2004-2009 Toyota Harrier FWD]
Cusco 924 311 B18 18mm rear sway bar [2004-2009 Toyota Harrier FWD]

✅ Vented rear brakes (On '08 RX350)
✅ Roof rack delete
✅ Freer-flowing muffler, resonator & catalytic converter
✅ Freer-flowing y-pipe
✅ ARP wheel studs
❌ Coilovers

Pros:

• Soft handling is gone - more responsive during hard driving
• The car can actually oversteer now, with a predictable throttle lift-off at the limit
• Body roll and nose dive have been reduced heavily
• Less wind noise and better mileage on the highway
• Greater stability and confidence at highway speeds or during emergency maneuvers
• Harder to break traction, tire squeal is lower pitched and happens later
• Exhaust is a lot louder and deeper, but very subtle until you get on it
• Acceleration is more responsive
• More confidence in the brakes with SS lines and bigger rotors / calipers

Cons:

• Unpsrung weight is increased from the heavier brakes, wheels, tires and knuckles
• Slightly harsher ride
• Small bumps can be felt more easily due to stiffer suspension, lower profile tires and wider rims
• Speed bumps jostle car more due to the larger sway bars
• Less compliance and more bump-steer on bumpy/bad roads

Result: The car is a lot nicer to drive! It sits as low as a Camry, and handles a lot better than one too! You wouldn't believe you were driving a 20+ YO 4000 lb SUV down the road. Lots of handling potential has been gained without a loss of practicality or a big hit in comfort. I chose to go with bigger sway bars instead of stiffer springs or coilovers to retain a lot of comfort while reducing a huge amount of body roll. The rigidity of the chassis and the feedback of the hydraulic steering can be appreciated more as well.

Off-road build?:
❌ Lifting springs
❌ 2nd gen rear struts & 2nd/3rd gen front struts
❌ Disconnected sway bars
❌ Mud tires
❌ Skid plate
❌ Bull bar
❌ Sienna 150A alternator
❌ 94R battery
❌ Snorkel

Result: People seem to be happy with their Highlanders off road! I would never do it due to the unibody design and Camry underpinnings, but they do seem to make it work.


My favourite performance mods in order:

Addco 2109 22.2mm rear sway bar & My "MKII" custom rear sway bar brackets
- Transforms the Highlander into a lift-off oversteering beast at the limit. Stiffens up the rear and allows for greater turn in, this is what made the car the most fun to drive. My custom brackets tie into more of the frame and don't flex like the stock AWD ones, which allows for full sway bar potential. My brackets also use a universal bushing for cheaper and easier to find replacements.

AWD 2nd gen 26mm front sway bar
- Keeps the oversteer in check and keeps the front flat while cornering, increases the car's limit before traction is lost. Surprisingly good addition for our AWDs without cutting down on that oversteer. Bonus: Comes with heavier duty brackets & bushings are easier to source out. Brackets and bushings can be found from as far back as 2004 to 2020 on the Sienna. Even w/o the rear bar, the front bar with our front suspension helps keep the camber angles in check which is why I'm guessing it doesn't induce more understeer.

H&R RX300 lowering springs & KYB struts
- Reduces that annoying nose dive upon braking and acceleration. Lowers the center of gravity for better handling and works in conjunction with the sway bars to keep the car flat and sporty. The KYB Excel-G struts were a nice combination for these springs considering my blown factory struts had 240k km on them!

Custom exhaust
- A nice exhaust that I pieced together helps me enjoy the sound of the 1MZ-FE which keeps me entertained while I drive the HL. The exhaust is lighter and less restrictive than stock, while having an OEM+ appearance as well as no drone. Just the way I like it! Opening it up results in a nice, throaty sound that is not overly loud at all. Cruising is a mellow and deep note.

2nd gen brakes (front & rear)
- The stock Camry brakes weren't cutting it. Now that my car can handle a lot better, it deserves some better brakes that don't hot spot. These 2nd gen brakes are a lot beefier and should not fade under any normal circumstances due to how massive they are for the size and weight of our 1st gens. I feel like I won't be needing to do as many brake jobs in the future as well. Rear alloy calipers cut down weight, and the Akebono caliper's design makes servicing a lot less of a hassle! I prefer the more bitey "GG" rated Raybestos EHT pads over the "FF" rated Akebono ProACTs, but they're both solid.

Roof rack delete
- Now that the 2014 RX is the new "hauling / trip" vehicle for the kayaks and short errands, the Highlander is reserved for the dirty jobs that usually involve loading up the entire interior's volume with crap and going for super long highway drives. Knowing this, I figured I'd take the roof rack off to lower the center of mass and help improve highway mileage. Taking the rack off shed ~20 pounds, cut down on wind noise and certainly improved the look of the car in my opinion.



My favourite "daily" mods:

Dashcam setup
- My hardwired Viofo front & rear cam setup is the no. 1 critical addition to commuting. These bad boys keep me covered from any of the crazy crap that occurs on the road. Optional bonus includes: watching said dashcam clips is entertaining

Pioneer AVH-2300NEX
- Super essential creature comfort on a daily drvier. Load up some tunes and play them on your commute, use Waze to spot cops and report hazards - all controlled by a nice touch screen. Bonus includes: Hands-free calling, a reverse camera and a built-in amp to help bring out some life in the JBL speakers.

Buick Park Avenue horns
- We all know how wimpy Toyota horns are, and when my original horns died - there was only one option. Buick horns running straight off battery power with a 30 amp relay deliver the appropriate amount of volume for any distracted driver who dares make the mistake of drifting into your lane.

3MZ-FE revised valve cover
- Having to constantly add oil is not fun, and cleaning up leaking oil in your engine bay and on the floor is even less fun. The "gen 2.5" 3MZ cover wasn't exactly the latest edition, but it eliminated my oil burning issues I had with my old cover. I'm sure the ol' 'Lander enjoys this mod as much as I do.

LED Hybrid Taillights & LED third brake light
- A good safety mod as well as an aesthetically pleasing one. Bright LEDs help your visibility while braking. The Hybrid tails have better coverage & brighter turn signals and reverse lights as well due to the design of the housing. Not having to change bulbs and worry about ground wires is also nice. These LED assemblies really help modernize the car's appearance.

Rubber floor mats & trunk liner
- Salty, slushy carpet during the winter is no fun. Getting WeatherTechs was a little pricey but dealing with that hassle is far worse. I just leave them in all-year and they work beautifully. Equally as important is a bucket-style rubber trunk liner. It fits the Highlander's trunk perfectly and helps keep my trunk clean. It also has a nice grippy surface so it helps keep items in place and reduces NVH.

LED footwell lights & LED interior lights
- I never knew I wouldn't be able to live without these until I installed them into my car. They fade on and off with the dome light when you open the door - which completes that OEM+ feel that I crave. These help give the car a more luxurious and modern feel, while helping me locate the parking brake and pedals while entering my car at night. It also comes in handy if I drop something from my seat.

Sound deadening
- A little bit of extra weight worth of sound deadening goes a long way. I stuffed this stuff into all four doors, the trunk lid, the spare tire area, the rear wheel wells and behind rattling trim panels. The result? No more rattles at all and a very quiet ride! The fun part was seeing my passengers (EVERY single one of them!) who are not car people at all ALL notice the day after I installed it! It really makes a big difference in the NVH department and the car is a lot more Lexus-like in the way it handles road noise. Tire noise, car horns & wind noise have been reduced quite a bit. The original speakers can be appreciated more & the doors also sound nicer when you shut them.

Rear all-weather mat [2008-2013 Highlander] (A little tight, but fits)
Armrest [2004-2009 RX] (Fits, but I feel it is a downgrade from a 99-03 RX or 01-07 HL because it is shorter, skinnier and less padded)

Front headrest [2001-2007 Highlander] (Interchangeable. 04-07 are more large and fold backward instead of forward - colour is same)
Front headrest [2004-2009 RX] (Very similar to 04-07 HL ones, slightly smaller)
Front headrest [2010-2015 RX] (While it fits the spacing, it doesn’t latch in place properly. Also a downgrade as there’s less padding and they don’t slide forward or back)
Rear headrest [2004-2009 RX] (Won’t fit an 01-03 HL)
Rear all-weather mat [2014-2019 Highlander] (Interferes with console)
Steering wheel [2004-2008 Solara] (Fit perfectly on a 2002 after the detonator was swapped and CC was adapted)

Sunvisor [1999-2003 RX] (Won't fit without 3D printing a custom mount clip. I highly recc not to bother with these. They resemble an 01-03 HL sunvisor, but the material is cloth instead of vinyl. They have a different electrical connector too, but mount up to the car properly. The sunvisor clip is 10mm instead of 12mm. These extend out but they are a little flimsy)
Sunvisor [2005-2011 Avalon] Can fit see PetayV8’s post. Resembles an 04-09 RX visor w/ 01-07 mounting
Trunk lift supports [2005-2012 Nissan Pathfinder] (A little strong, but much better quality as well as cheaper than the junk they offer for our cars)
Blower motor [2004-2009 RX, 2004-2010 Sienna] (Too small to fit)

Gauge cluster [2006-2007 Highlander Hybrid] (Won't fit 01-07, wiring, faceplate and more is different)
Subwoofer [1999-2003 RX300] (For 01-03 only! 4.5" woofer in a ported box. Bolts down to the front passenger seat bracket with the two front bolts, but not the rear as the RX300 has a different floor. It works great for how cheap they are at the junkyard! Will not work with 04-09 RX front seat or other height adjustable seats)
Cluster cover 83852-48550 [2006-2007 Highlander Hybrid] (Lexus-style smoked gauge cluster cover, it fits perfectly and makes the instrument panel dark when the car js off, thanks @AlexMan for confirming!)

Front brakes [2016-2022 RX] - Same as above but uses M14 x 1.5 mounting bolts
Rear brakes "Highlander BBK" [2008-2013 Highlander] - 309x10mm rotors Direct fit for 2004-2007 models, 2001-2003 models need to swap to 04-13 rear knuckles, modify driver’s parking brake mount, swap to 2004-2007 rear control arms, 2004-2007 CV axles and 2004-2007 rear toe bolts, dust shield needs to be bent backward if using stock 04-07 one. Stock brake lines fit perfectly - 16” wheels minimum required - stock lines fit
Rear brakes "Highlander BBK" [2014-2019 Highlander, 2011-2020 Sienna, 2010-2015 RX] - Reuse the 2nd gen rear rotors with 3rd gen Highlander rear calipers and pads. This caliper is a little less beefy, and the pad is slightly shorter but taller. The benefit of this swap compared to the 2nd gen rear calipers is that the 3rd gens are way more common to find used, and pad choices are better as it's a highly used part. 17" wheels minimum required, stock lines fit
Front brakes [2002-2003 ES300, 2004-2006 ES330] - Can run stock 296x28mm rotors & 16" wheels, but dual piston like 2nd gen brakes
Front brakes [2004-2009 Lexus RX, 2006-2007 Highlander Hybrid] - Larger rotor (319x28) and single piston caliper, same piston diameter - 17" wheels minimum required
Front brakes [2020-2023 Highlander, 2023+ RX] - 340x28mm rotor, similar cast iron dual piston caliper to 2nd gen except takes different pads, uses M14 x 1.5 mounting bolts instead of M12 x 1.25, so knuckle may have to be drilled, unfortunately requires an 18" wheel
Front brakes [2021-2023 RAV4 Prime, 2022+ Lexus NX450h+] - 328x34mm rotor, similar cast iron dual piston caliper to 2nd gen except wider to accommodate a 6mm thicker rotor, takes same pads, uses M12 x 1.25 mounting bolts like usual, requires 17" wheel
Front brakes [2021-2023 Sienna] - 328x34mm rotor, similar cast iron dual piston caliper to the RAV4 Prime and newer gen NX except wider to accommodate a 6mm thicker rotor, takes same pads, uses M14 x 1.5 mounting bolts instead of M12 x 1.25, requires 17" wheel

Front brakes [1993-1998 Supra] - Test fit by Lexus RX330 owner, fitment was unsuccessful
Front brakes [2007-2023 IS350] - Test fit on 3rd gen Sienna, the calipers weren't possible to mount due to the clocking of the caliper, even with multiple custom bracket designs
Front rotors [Supra TT] - Test done by RX330 owner with 2nd gen front calipers. Directional rotors. They had to be machined thinner to fit the calipers properly

Vented rear brakes [2006-2014 IS350 & 2010-2015 RX (EURO)] - 310x18mm rotors. Fitment identical to 2004-2013 models. Parking brake works perfectly and can be adjusted, hub fitment is identical to stock. Like the 2nd gen rear brakes, you will need an 04-07 or the respective knuckles, and you will need to either modify or use 2nd gen or Venza rear dust shields, the calipers require 2.5mm washers behind the mounting bolts to clear, and are based off of 2014-2019 Highlander ones. They share the same hardware & pads. Stock brake lines fit perfect - 17" wheels required to clear

Steering:

Gates 349770 [1988-2002 Corolla] (90 degree elbow used to convert our power steering rack return line to all rubber, thank you Ralph Spoilsport for this discovery!)

Front knuckle, hub & wheel bearing assembly [2004-2007 Highlander] (Couldn't find one for a 2001-2003, fit was identical to my original parts other than the outer tie rod. Solution is to run 2004-2010 Sienna outers. If you want to change both, you will need 2004-2007 Highlander inners or 2004-2010 Sienna inners, and 2004-2007 Highlander outers)

Front knuckle, hub & wheel bearing assembly [2008-2013 Highlander] (Unlike the rears, these front knuckles resemble do not fully resemble 2004-2007, but they are beefier. The only difference is that you will need 2011-2014 Dodge Charger inner tie rods, 2nd gen outer tie rods, different brake dust shields, wheel bearings and a deflector/dust cover for the CV axle. Everything else fits like hub, ABS sensor, ball joint, strut and CV axle)

Rear knuckle, hub & wheel bearing assembly [2004-2007 Highlander, 2004-2009 RX] (The 2004-2007 Highlander rear knuckles are beefier, have bolt-on wheel bearings, and they allow you to run the 08-13 rear brakes. You will also need 2004-2007 rear control arms, ABS sensors, rear CV axles and 2004-2013 Highlander or 2009-2015 Venza rear dust shields if you want to retain the parking brake. Saving the parking brake requires a hole on the driver's side shield to be bored out in order to bolt on the cable)

Rear knuckle, hub & wheel bearing assembly [2008-2013 Highlander, 2009-2015 Venza] (This version fits like the 04-07 but is even thicker. They include a larger dust shield/backing plate to accomedate the big 2nd gen rear brakes without having to trim anything. The Venza dust shields are slightly different compared to the Highlander ones, they sit a little closer to the larger 08-13 rear caliper, 04-07 ABS sensors will work fine with these knuckles)

Intermdiate shaft [2004-2009 RX] (Slightly longer than 01-03 intermediate shaft, otherwise fitment was identical, bought as finding a suitable aftermarket replacement wasn't easy)

Suspension:

Rear sway bar bushings 16mm FWD [1997-1999 Avalon, 1997-2001 Camry, 1999-2003 Solara (V6 or Convertible), 1997-2001 ES300, 2004-2009 RX FWD]

Rear struts [2004-2007 Highlander] (These work fine, but you need to use an 01-03 strut mount as the 04-07 strut mount's studs are a larger diameter and would require drilling. Another issue is the sway bar end links are a little shorter on the 2004-2007 models, but they still fit. This causes the sway bar to be pointing down a little bit due to the positioning being lower on the 2004-2007 struts - making the sway bar a little softer.)

These work great and are easier to find parts for incl the pads. You will need to use a 08-13 rear rotor to retain the parking brake
Rear Calipers & Rotors [2006-2013 IS350, 2006-2011 GS] (Big 44mm piston vs 38mm, 18mm vented rotor vs 10mm solid, 310mm diameter rotor vs 288mm. The IS rotor perfectly fits the hub and allows use and adjustment of factory parking brake. You will need Euro-spec 2010-2015 Lexus RX350 calipers to do the swap
Rear ABS sensor [2008-2013 Highlander AWD] (Tried to pull this off on my '08 RX350 AWD because they're around half the price and more corrosion resistant. The project ended up being a massive fail as I couldn't get the sensor to play nice with my tone rings. These sensors cannot be made to work, they are also not as magnetic as regular 04-07 sensors.)
