Drivetrain Pinion Shims for Correcting Driveline Angles
Changing the ride height on a leaf-spring rear axle also changes the angle of the pinion relative to the driveshaft. When that angle drifts too far, you may feel vibration under acceleration, and the U-joints work harder than they should. Pinion shims are wedges that sit between the spring and the axle mount. They rotate the housing slightly to bring the pinion back into line. Owners who lower or lift a truck often fit them as part of the same job.
This page, found under Drivetrain › Pinion Shims, currently lists 3 in-stock products, all from Belltech. Options include the Belltech Pinion Shim Set 1 Degree (Pair) and the Belltech Pinion Shim Set 2 Degree (Pair), so you can choose a smaller or larger correction.
A few things to consider before you order:
Measure your current pinion and driveshaft angles rather than guessing.
Start with the smallest correction that brings the angles back into range.
Confirm which direction the wedge needs to face for your setup.
Check that your U-bolts and mounting hardware suit the added thickness.
Use the selector to pick your vehicle and see which Drivetrain Pinion Shims fit.
