Magnaflow cat, lift block, and BJ spacers

[knj27]

Ok, 3 quick questions:

First, if I have two O2 sensors, that means it's a Cali truck, right? So will this cat be OK on my truck? http://www.autopartswarehouse.com/de...l?reviews=true

The description says use only on cali vehicles that are pre-OBDII. A 93 truck isn't OBDII, is it?


Second, where can I find some 2" lift blocks (and the longer U-bolts I'm assuming I'll need) that will fit my truck?


Lastly, are there any ball joint spacers out there besides the 1.5" SDORI ones? I haven't run into any, but maybe someone else knows. Is there such a thing as 2" bj spacers out there, so I don't have to crank the torsion bars to make it level with 2" blocks in the back? Hopefully 2" of lift all the way around will be OK with the stock length shocks. I know I can shim the fronts a bit, don't think so on the back.

Any help with my random little set of questions is appreciated.

It looks like it should be fine

96+ vehicles are OBD-II

1.5" BJ spacers is the biggest I've ever seen, no matter who is selling them.
You could always get 1.5 in blocks or 1.5" lift shackles instead of 2" blocks.

How much do you have to crank the torsion bars to get half an inch? Will that affect my ride roughness all that noticabley? Thanks for your help.

[fourwd1]

The actual amount you have to "crank" them is going to depend on how old and worn they are.

Typically half an inch isn't real noticeable on the ride quality.

I'm currently running that cat and I live in Cali, shouldn't be a problem. As other fourwd1 said, 96+ are OBDII. Bought it straight from 4wheelparts for $90, came in about 4 days. Had to buy new gaskets and bolts from NAPA for about $12. (mine were stolen)

[knj27]

Ya I knoticed that you have to buy gaskets seperately with that cat. I could just buy a universal instead of the direct fit, but I've already made my buddy that knows how to weld do to much work for me.

I live in AZ, so passing emmisons (which I actually did like a month ago) isn't my problem, I just wasn't sure if the cat would affect any sensors/electronics at all. But apparently it'll be fine.

So I guess I need $130 for the bj spacers, $30 for lift blocks (autozone ones anyway, do you think that is legit enough?), $60 for a good alignment, and $90 for the cat. So add it all up and throw in some tax and shipping, and I need to come up with like $340 I can justify spending. Once I pull 2 or 3 more paychecks in, me and a couple buddies can probably knock that out in a weekend. I'm looking forward to it.

Thanks again for all the help!

Do you have AAL in the rear? If not those old springs are sagging, therefore with the BJ spacers, which are available from 4Crawler (my allen heads are rusting though) the block and spacers discrepancies will level the truck or very nearly do so.

$30 sounds way low for decent blocks, good ones are about twice that.

You'll also need longer U-bolts.

First off, please do NOT get lift blocks. Save up an extra few bucks and get something better.

I would go with a long style AAL kit, this should net you 1-2" of lift. Get a longer rear shackle to get the arse end up to match the front if you want. This will give you a better ride and more functionality then straight up lift blocks.

I wouldnt trust the autozone specials under my leafs!

4crawler.com sells the bj spacers, I hear he sells them cheaper....

[knj27]

Ya, the 30 dollar ones are the autozone special and they come with extra long u-bolts. I was pretty sure everyone here would tell me that wasn't legit. We'll have to think about that one...

I checked 4crawler, the bj spacers are $109 + $7-20 shipping...

My O'Reilly's blocks are fine. There is nothing wrong with blocks unless they're fifteen inches long. With longer shackles you springs are under more pressure, with an AAL they'd be more relaxed. The only problem I had with the blocks was the U-bolts were garbage, I already had the U-Bolt flip kit from Downey so there wan't a problem. People always say bad things about blocks but never give their own personal experience. Also the one's that fuck up are the ones rednecks make that are 20 inches tall with Rockwells and big tires. So for you a 2" block would be just fine. Remember to torque the nuts though.

[yota44]

I've never heard of anyone running blocks with Rockwells lmao. Rednecks arent the only people that use huge blocks.

[knj27]

Ya, I was thinking about puttting the blocks on and getting the nuts really friggin tight, and then maybe tacking the blocks on in a few spots, just for added strength. But you could still pound them off if for some odd reason they needed too come off.

I'm gonna call Checker/Pep Boys today and see what they have as far as cats...

I'm still laughing about the picture now in my head of some redneck chevy with Rockwells sitting on 15" blocks.

Blocks are the worst way to lift a truck. End of story! Putting a set of blocks under your saggy toyota springs is gonna do a few things for you:

1. Yeah sure, it'l lift it up and make it look okay..
2. You're springs are gonna start to look like a W
3. You're gonna get a good amount of axle wrap

Do what you want.. but I would advise against lift blocks. And yes, I DO have experiance with them..

[yota44]

Small lift blocks are fine, alot of trucks have small blocks on them from the factory
