What does a pinion shim do?

A pinion shim is used to adjust the angle of your rear axle's pinion gear. When this angle is off, often due to suspension modifications like lifting a vehicle, it can cause driveline vibrations. The shim helps to bring the pinion angle back into alignment with the driveshaft, reducing or eliminating these vibrations.

What is included in this kit?

This kit includes two 2-degree pinion shims, two new spring centering bolts, and two nuts. This hardware is necessary for properly installing the shims between your leaf spring and axle.

Will these shims fit my leaf springs?

These shims are designed to fit leaf spring packs that are either 2.5 inches or 3 inches wide. They also accommodate applications that use either a single or a double center pin design.

Product Details

If you've recently lifted your truck or made other suspension changes, you might notice some unwanted vibrations coming from the driveline. That's often because the angle of your rear axle's pinion has changed. This Belltech pinion shim set is designed to help you correct that angle, bringing it back in line with your driveshaft to smooth things out.

These shims are made from strong ductile cast iron, so they'll hold up under load. They're designed to fit between your leaf spring and your axle, and they come with new spring centering bolts and nuts to make installation straightforward. This particular set gives you a 2-degree correction, which is a common need for many lifted vehicles. They're made to fit leaf spring packs that are either 2.5 or 3 inches wide, and they work with applications that have one or two center pin bolts.

This kit includes two shims and the necessary hardware to get them installed. It's a pretty common fix for driveline vibrations after a lift, and it's a solid option for getting your truck running smoothly again.
