What is the purpose of axle shims?

Axle shims are used to adjust the angle of your rear differential, often after installing a lift kit. This adjustment helps to correct the pinion angle of the driveshaft and reduce vibrations.

How do these shims reduce vibration?

By rotating the rear axle slightly, these shims bring the driveshaft's pinion angle back into a more optimal range. This reduces stress and vibration caused by the altered angle from a lift kit.

Where do these shims get installed?

These axle shims are designed to be installed between the rear leaf springs and the axle housing. They require the vehicle's weight to be supported safely, typically with the axle suspended.

About this part

Product Details

These Tuff Country axle shims feature a 2-degree taper and 3/8-inch center pins, designed to fit between your rear leaf springs and axle. They are specifically made to adjust the angle of your rear differential, which is often necessary after installing a lift kit. When you lift the rear of a truck or SUV, the pinion angle of the driveshaft can change, sometimes leading to noticeable vibrations.

By installing these shims, you rotate the rear axle slightly to bring the pinion angle back into a more optimal range. This helps to eliminate or significantly lessen those unwanted vibrations, making your ride smoother and reducing stress on your drivetrain components. They are a well-built solution for addressing common issues that arise from suspension modifications.
