Idon't know what degree i need yet ,but where can you get them??

 

Any 4wd shop should have shims. I did a 2/4 drop on my '99 RC FS, installed shims this weekend. The job wasn't too bad. One suggestion is do one side at a time. Also, put the truck on jackstands some where on the frame and then raise and lower the rear end with a floor jack. I found it helpful to jack rear axle up then put a jackstand in front of the axle under the leaf spring. That way, when you lower the axle the leaf spring doesn't move, it gives you more seperation between the axle and leaf spring. More room to work when swaping the the leaft bolt (installing shims will require the leaft bolt to be changed to a longer one) and installing the shim.

 

Thanx ..got some!!
