SPC Performance Angle Shims

Universal 1.5 Degree Pinion Angle Shims for 2WD and 4WD Trucks and SUVs (10642)

Part #: 10642

Overview

The SPC Performance Angle Shims are precision-engineered components designed to help you achieve optimal driveshaft alignment in your truck or SUV. Whether you're dealing with lifted, lowered, or modified suspension setups, these universal shims allow you to fine-tune the pinion angle, reducing driveline vibrations and improving overall drivetrain performance. Crafted from high-quality materials, these shims are built to withstand the rigors of off-road adventures, daily driving, and performance applications.

If you're experiencing vibrations, uneven tire wear, or noise from your drivetrain, improper pinion angle could be the culprit. The SPC Performance Angle Shims provide an effective solution to correct this issue, ensuring your rear differential aligns properly with your driveshaft. Designed for both 2WD and 4WD trucks and SUVs, these shims are ideal for enthusiasts looking to restore factory alignment or optimize their suspension geometry after modifications.
