SPC Performance Angle Shims

Universal 4-Degree Pinion Angle Shims for Trucks and SUVs (10572)

Part #: 10572

Overview

The SPC Performance Angle Shims are precision-engineered components designed to correct and optimize the pinion angle of your vehicle's rear differential. Whether you're dealing with lifted trucks, modified suspensions, or simply seeking to restore proper driveshaft alignment, these shims provide a reliable solution. Crafted from high-quality materials, they help improve driveline angles, reduce vibrations, and enhance overall vehicle performance. Ideal for off-road enthusiasts, towing applications, or daily drivers experiencing driveline issues, these shims ensure your suspension geometry remains in optimal condition.

By adjusting the pinion angle, you'll experience smoother power transfer from the driveshaft to the wheels, which can lead to increased component longevity and a more comfortable ride. These shims are designed for easy installation and compatibility with a wide range of vehicles, making them a versatile choice for both professional mechanics and DIY enthusiasts.

Key Features

SPC Performance Angle Shims are built with durability and precision in mind, offering a straightforward solution to common suspension alignment challenges. Their key features include:

• Constructed from high-quality HD zinc alloy, aluminum, or manganese bronze for exceptional strength and corrosion resistance.
• Available in various widths and degree corrections to accommodate different vehicle setups and suspension modifications.
• Designed to change the pinion angle by 4 degrees, helping to restore proper driveshaft alignment and reduce vibrations.
• Manufactured with precision machining to ensure a perfect fit and consistent performance.
• Suitable for both 2WD and 4WD trucks and SUVs, providing a versatile solution for a wide range of applications.
• Easy to install with common hand tools, requiring no specialized equipment or modifications.
• Helps improve driveline angles, reduce drivetrain noise, and support the longevity of drivetrain components.
• Offers a cost-effective way to enhance vehicle handling and reduce mechanical stress caused by improper pinion angles.

Construction & Design

The SPC Performance Angle Shims are crafted from premium materials such as high-density zinc alloy, aluminum, or manganese bronze, ensuring they withstand harsh conditions and resist corrosion over time. Their precise machining guarantees a snug fit and reliable performance. The design features a simple, effective shape that allows for quick installation and removal, making them an excellent choice for both professional garages and home mechanics. The shims are engineered to provide a 4-degree correction, which is a common adjustment needed after suspension lifts or modifications that alter the original pinion angle.

The use of durable materials and meticulous manufacturing processes ensures these shims maintain their shape and effectiveness even under demanding driving conditions. Their compact design minimizes added weight and complexity, while their robust construction ensures long-lasting performance.

Installation & Fitment

Installing the SPC Performance Angle Shims is a straightforward process suitable for most DIY enthusiasts and professional technicians. The shims are designed to fit between the differential housing and the leaf spring or suspension mounting points. No cutting, drilling, or complex modifications are required—simply remove the existing hardware, position the shims, and reassemble. It is recommended to verify the correct degree correction needed for your specific vehicle before installation.

For optimal results, it may be beneficial to perform a wheel alignment after installing the shims. The process typically takes less than an hour, making it a quick and effective upgrade to improve your vehicle's suspension geometry.
