What do axle shims do?

Axle shims are tapered pieces installed between the leaf springs and the axle housing. They rotate the axle to correct its angle, which is often necessary after installing a lift kit to prevent vibrations.

What is included in this pair of axle shims?

This kit includes two 6-degree axle shims, each 2 inches wide, with 3/8 inch center pins. They are designed to work together to adjust your rear differential angle.

Why would I need axle shims after installing a lift kit?

Lift kits can alter the pinion angle of your rear differential. This change can cause driveshaft vibrations. Axle shims help to re-align the differential, reducing or eliminating these vibrations for a smoother ride.

About this part

Product Details

In this kit, you get a pair of Tuff Country 6 Degree Axle Shims, each measuring 2 inches wide and featuring 3/8 inch center pins. These shims are made to fit the rear end of most trucks and SUVs that use leaf springs. They are specifically designed to adjust the angle of your rear differential.

When you install a lift kit, it can sometimes change the angle of your rear axle, leading to unwanted vibrations. That's where these shims come in. By placing them between your rear leaf springs and the axle, their tapered design rotates the rear axle housing. This rotation helps to eliminate or significantly lessen those annoying rear-end vibrations, making your ride smoother after a lift.
