JBA Offroad control arm question

I agree that the extra castor may not help at stock height. After a lift I didnt need the JBAs until I put bigger tires. With the lift and tires, I was rubbing and my steering would wander at highway speed. (Alignment in spec)

After getting it aligned with 3 deg of castor the run went away and highway stability came back. If you aren't having these issues I wouldn't recommend changing to the JBAs.

On another note,, the UBJ maintenance with the JBAs is going to be WAY easier than OEM.

 

Personal experience on aftermarket UCAs. The alignment shop should be able to align the truck within spec but it won't be dead on with stock UCAs. The aftermarket UCA's help with the caster; the picture is my truck on OME882 with JBA UCAs (the before was my eyeball/driveway alignment).

Not sure if it's been answered, but I believe that all 6lug Tacomas came with the same front coils (spring rate & height). But a I4 Pre-Runner regular cab sits higher than a V6 4x4 double cab, it's due to the weight.
