With a 2.5 inch lift do i need upper control arms?

That was my 2nd gen lol. Hence the post in 2009

 

What if your just lifting the truck 2”. Will there still be enough adjustment left to align the truck to stock?

 

So with two inch spacers I shouldn’t worry about the upper control arms?

 

You should get new UCA’s with any lift if you want a true alignment. However, I have a 3” lift and am running stock upper control arms, although I did get an alignment after installing the lift. I have had the lift on for over 75k miles and I have not experienced any issues with uneven tire wear. The truck does wander quite a bit more than it did stock, but that’s due to an incorrect caster angle now. It’s not horribly noticeable, but on windy days it’s a lot worse than it was when stock.

 

Mine is at 2 inches. It wondered all over the road because of the "close to 1.5" caster. I put on JBA arms, now its 0 camber, 0 toe, and 3.15 of caster. It drives straight as an arrow and doesn't wonder around or feel like a passing 18 wheeler is about to blow me off the road.
