Leaf Spring Axle Shims

Our axle shims come in 2, 4, 6, or 8 degrees and they include 3/8" center pins. They go between your leaf spring and your spring perch to adjust pinion angles. Our shims are steel, we recommend you avoid any cast shims (speaking from experience). They are 2.5" wide and sold in either pairs or a set of 3 for Dana 60 axles. If you need any help calulating your pinion/driveshaft angles there are some great resources around with calculators included:
