Thoughts on different axle shims?

like many others i have vibs after my lift. at first start for a second then around 25-40
prob worse when driving at almost exactly 30mph in town. before you remove it or say search button. I'm trying to choose between the diff styles and makers. I'm going to go with 2.5 degree shims and i couldn't measure stock angles because i had a busted leaf spring so its ind of a crap shoot. bilstinlifts.com has 2 diff kits one in which you choose your degree and one from toytec that is just a generic 3 degree i believe for trucks with 2-3in of lift. then there is the kit from headstrong that is the open end slip in style. what are peoples experiences with any of these kits and why did you go with one over the other?

 

I bought mine from wheelers I believe. 3 degree shims and a carrier bearing drop fixed my vibes, but every truck is different.

This information is 17 years old ...FWIW.....

I had a 96 tacoma and had the leaf springs re-arched for 2" lift. The newly arched springs were more like 3" at first. Took a good 6 months for them to settle down to 2".

I installed 2.5 degree shims. That was the smallest shims you could buy at the time. You really can't get much smaller than that or else the metal is just too thin to even bother. The shims worked great and even after it settled - I didn't have any vibes at all. The shims were installed for 5 years.

The one thing I will note - try to avoid getting alluminum shims. I never had any problems with mine at all. They were installed on my truck for 5 years. However - I'd heard that some folks experienced the aluminum flattening out (because it's soft) over-time thus the ubolts were loosening - can be a really bad thing.

In your situation..... Vibrations are different for every truck. Buy the 2.5 or even 3 degree shims, install them yourself and see what happens. If it doesn't work - you can easily take them out and try something else.
Good Luck!
