SPC Performance Angle Shims

Universal 2-Degree Pinion Angle Shims for Trucks and SUVs (10532)

Part #: 10532

Overview

The SPC Performance Angle Shims are precision-engineered components designed to correct the pinion angle of your vehicle's rear differential. Whether you're dealing with driveline vibrations, uneven tire wear, or simply restoring proper alignment after suspension modifications, these shims provide an effective solution. Crafted for both 2WD and 4WD trucks and SUVs, they help optimize driveshaft angles for smoother operation and enhanced drivetrain longevity.

Ideal for off-road enthusiasts, towing professionals, and daily drivers who have experienced suspension lift or leveling, these angle shims ensure your vehicle maintains optimal driveline geometry. By adjusting the pinion angle, you'll experience improved power transfer, reduced vibrations, and increased component durability, all while maintaining the factory ride quality and handling characteristics.

• Enhances overall driveline stability, reducing vibrations and noise for a smoother ride.
• Designed with ease of installation in mind, requiring minimal mechanical expertise and no specialized tools.

Construction & Design

The SPC Performance Angle Shims are crafted from high-quality, durable materials such as HD zinc alloy, aluminum, or manganese bronze, ensuring they can withstand the demanding conditions of off-road and heavy-duty use. The precise machining process guarantees a perfect fit, which is critical for maintaining proper pinion angles and preventing driveline vibrations.

The design features a simple yet effective wedge shape that seamlessly integrates between the leaf spring and the differential. This allows for easy installation without the need for extensive disassembly or modifications. The choice of materials not only provides strength but also offers excellent corrosion resistance, ensuring long-lasting performance even in harsh environments.

Installation & Fitment

Installing the SPC Performance Angle Shims is a straightforward process suitable for DIY enthusiasts and professional mechanics alike. The shims are designed to bolt directly between the leaf spring pack and the differential housing, requiring only basic hand tools. No cutting, drilling, or complex adjustments are necessary, and the process typically takes less than an hour.

For best results, ensure your vehicle is securely lifted or supported on jack stands before beginning installation. Follow the included instructions for proper placement and torque specifications. Once installed, it is recommended to verify the pinion angle with a digital angle finder or inclinometer to ensure precise correction.
