Superlift 6 Degree Pinion Shim/Wedge - 2.5in Leaf Spring

This 6-degree pinion shim is made from aluminum and designed to fit over your axle, working with 2.5-inch leaf springs. When you lift a vehicle, the angle of your rear axle changes relative to the driveshaft. This shim helps to correct that angle, reducing vibrations and wear on your U-joints and driveshaft. It's a common part to install after adding a lift kit to ensure your drivetrain runs smoothly.

Superlift has been around since 1975, and they build their parts with the understanding that most trucks spend their time on the road. This means you get a part that's designed to perform well both on and off-road. These shims are sold as a pair, so you'll have what you need to adjust the pinion angle correctly.
