Hey everybody,

I know some people had the question of where to get steel axle shims. I found a place that has them in the correct 2.5" width.

http://www.bentandtwisted.com/catalog/index.php?cPath=49&osCsid=bc2e2414d970d5bff4d3336219d65c04

Next was a question that I have. I put on a set of Deaver mini pack AAL's that gave me about 2" of lift. I'm getting a minor driveline vibration at about 30 mph (only accelerating or decellerating in gear) and can barly feel anthing if anything at other speeds. What degree of shim works that you have all found? I have stock shackles as well.

(I'll ad a new post with pictures of my new lift and tires once I download them from my camera.)

Thanks,
Dan

Dan, Call and ask Calmini what degree they use for their AAL. I had all kinds of problems with the AC AAL, but the Calmini with the shim, I have had no problems.

Jason,

I called Calmini and they said that their shims are 3 degrees for the 1.5" AAL. Potentially with 2" I might need 4 degrees, but I don't know for sure.

I've got 2" lift via AAL and used 2.5° shims from Rancho. No problems at any speed.





Its a little hard to see the shims, but you'll get the idea.

There's a good picture of a 2,0° shim from AC. And i trowed away the last leaf, you don't need it. No vibration at all.

3 degree shim with AC AAL, no vibrations at all. Have a set of 4 degrees on hand just in case the 3 degree didn't work, didn't need them after all.

so this may be a dumb question, but that hasn't stopped me before.

how do the center pins slip into the spring perch with shims? They aren't very long and I can imagine the shims causing the pin to not hold the leaf in alignment with the diff?

Most shims have a pin of their own milled into the shim. This is why steel shims are much more expensive than aluminum shims (they are harder to make).
