motoxscott said:I'd like to clear a few things up.
1) Our uniball upper arms were designed to be used with our Camburg coilovers, SAW, DR, King with 2"-2.5" of true lift. The problem with the stock arm is that when you raise the ride height you lose much needed castor. When I say 2"-2.5" of lift I mean exactly that. Many times people install spacer type lifts or different coil springs that say you're getting 2.5" but you get 1.5" or 3". Ride height is very critical when aligning the truck. We build more castor into our arms to correct the geometry flaw the stock arms create whe lifting the truck.
2) Measuring the tube of the arm and trying to compare it to other arms like Total Chaos's isnt going to tell you much. Our tube is around 7" and their's is 6.5". The main reason why the tubes are different lengths is because they dive their tube more towards the inside portion of the uniball cup and we have ours go more to the back for added clearance. Thats why the tube lengths are different. That will not effect geometry, placement of the actual uniball cup will. It's placement is dictated by the jig fixtures we build them in.
3) We have sold a ton of these arms and install a lot of them and dont have customers calling us back saying their truck wont align. We installed 5 sets of these arms the last part of Dec before xmas and every single truck aligned to proper specs. The problem lies a lot of times with alignment shops that dont really understand suspension geometry and are only trying to align the truck to factory specs. Well if we build an arm to add more castor to the truck, they are going to try and take out that castor because their printed manual tells them otherwise. If someones ride height is too high or too low, that will also effect the situation.
4) We use Dave's Frame & Alignment to align every truck we build. He is the best of the best. He's old school and doesnt use computers to align it nor do you need a computer to align the truck properly. If that werent the case then he wouldnt be aligning $300K+ race cars from some of the top road race teams were geometry is far more complicated and critical. Our little offroad trucks are a walk in the park for him ... but not for most. How many of your alignments shops you use actually understand suspension geometry and the handling characteristics of every change ... not many I'm sure. They know how to enter "2005 Toyota Tacoma" into a computer to tell them what to do.
Here's one of the trucks we just did with our coilovers set at 2" of lift with our uniball upper arms ... no alignment problems with this one and the customer couldnt be happier.
Looking at the pictures posted here, they are using our arms with a spacer type lift or a different coil spring. Well if the lift isnt a real 2"-2.5" then that could be why they are having an issue aligning the truck, or the person aligning it isnt doing it correctly. Their are many variables that cant be addressed online.
Feel free to call me at the shop if you have more questions. We'll continue to look into this but at this point I dont see a flaw with our product since we dont have alignment problems with our 2005-2007 Tacoma/FJ upper uniball arms, but we are always improving our product lines if need be and striving to build the best. Keep me updated and I will do the same.
