1.5" Wheelers 3 leaf Progressive AAL - Will I need Shims?

only going with 1.5" in the rear. will i need their 3 degree shims?

 

The word "need" leads me to answer the question with NO

Will the lift change the factory pinion angle, yep? Will 1.5" of lift cause you issues that are both noticable and harmful, Not likely

Am I talking out of my ass as if I know what the heck I'm talking about, maybe

Do I wear tighty whitys to hold everything in….. no comment

 

Mines lifted a little over 2.5" and I put 4 degree shims on and the pinion angle was more thrown off. I took the shims off and my truck feels fine. All in all I've heard you only really need shims if you're going 4" or bigger.

 

4 degrees

 

Yes........... That is correct haha
