BTF Steel Degree Shims (4 degree) are the solution to bad driveline angles. Steel degree shims are better than aluminum shims for one simple reason. Aluminum shims break easily, and steel shims will not. They are sold in pairs. Our steel degree shims bolt to the spring. You will need a longer tie bolt to attach them to the leaf pack. This can be purchased seperately.
