Part #: 86255

Overview

The SPC Performance Pinion Angle Shims are precision-engineered wedge-shaped spacers designed to help you fine-tune your vehicle's driveline alignment. Crafted specifically for Ford F-150, Raptor, and Lightning models within the specified years, these shims are ideal for enthusiasts and technicians seeking to correct pinion angles after suspension modifications. Whether your truck has been lowered or lifted, these shims support optimal driveline geometry, reducing vibrations and drivetrain stress for improved durability and performance. Constructed from durable materials, these shims are built to withstand the rigors of off-road and daily driving conditions. Their straightforward design allows for easy installation, making them a practical upgrade for suspension adjustments. Proper pinion angle alignment not only enhances vehicle handling but also prolongs the lifespan of your drivetrain components by minimizing unnecessary wear.

Key Features

Designed to fit the 2-hole rear spring and axle mounting points, these shims provide precise angle correction. Their wedge shape allows for easy adjustment of the pinion angle to match your vehicle's specific suspension setup. Made from high-quality materials, they resist deformation and maintain their shape over time. The simple bolt-on installation process makes them accessible for both professional mechanics and DIY enthusiasts. These shims are an essential tool for maintaining proper driveline angles after suspension lifts or drops, ensuring smooth power transfer and reducing drivetrain noise.

Construction & Design

The shims feature a wedge-type design with a robust construction tailored for automotive suspension applications. They are engineered to fit seamlessly between the rear spring and axle, with precise dimensions to ensure reliable alignment correction. The materials used are selected for strength and longevity, providing a stable and consistent performance over time.

Installation & Fitment

Installation involves positioning the shims between the rear spring and axle at the existing mounting points. This process typically requires basic hand tools and can be completed in a short period, making it a convenient upgrade for suspension tuning. Proper fitment is critical for achieving the desired pinion angle correction, and these shims are designed specifically for the listed Ford models and years.

Ideal For

Perfect for truck owners and off-road enthusiasts who have modified their suspension height and need to restore optimal driveline angles. These shims support improved handling, reduced vibrations, and enhanced drivetrain longevity, making them a valuable addition to your vehicle maintenance or upgrade routine.
