Axle Shim ?

For all you guys with vibs have you actually gone under your truck and did the angle measurements? From the sounds of the comments above it seems like most guys are just guessing without doing the measurements, if so what is keeping you from doing that?

 

Did you get your Icon leafs installed and if so what setting did you choose?

 

Yes, get under there and simply measure, it'll save you loads of work and mula.

Also, my other recommendation would be to stick to steel shims, not aluminum...issues with corrosion from dissimilar metals and soft aluminum as well.

There's some places that'll make custom shims for you, any angle you want in .5 degree intervals.
