So its time for a new 4.5 lift. When I put the 2" BB on top of the already higher upcountry suspension i got some vibes. I am not sure if they were within what some would call "acceptable parameters" but I put a t-case drop on and they went away. I am going to do an H'n'T SYE as soon as I get the ***** to hack off the shaft and drill that hole,but until then, I want to keep the drop and shim the axle. Which shims do you guys think I should use.

Thanks in advance for your help!

4*. That's what we use with the RE lifts from 3.5"-5.5" and it works well.

It works with the RE kits because the 4.5" and 5.5" kits use lift shackles which help tilt the pinion up. Even with just straight 4.5" leafs and stock shackles, I'd probably still go with 4*. Taller than that with stock shackles and I'd do 6*.
