Do I need UCAs??

aftermarket ucas allow you to get a perfect alignment, some trucks may not ever need them others do. also with aftermarket ucas you can get the most articulation out of your suspension. so if your not going to be flexing the hell out of your suspension all the time and your truck already drives straight down the highway and doesnt wander you probly dont need to invest in a set.

I would add that aftermarket UCA are configured so that they will provide more adjustability for the caster setting. I hear that most of these UCAs add 2 degrees of caster right off. This is important for lifted Tacoma's because the stock UCAs run out of adjustment. Again, I have read on here that the ideal caster number is 2.4 degrees positive. With a lift it becomes impossible to get that high a caster number. On my truck (~+2.5") it is not possible to get above 1.6/1.7.
