Solid Pinion Spacer w/ Shims

The Solid Pinion Spacer with Shims from RATECH is an essential precision component designed for differential assembly and pinion depth adjustment. It is ideal for mechanics and automotive enthusiasts who are either rebuilding a stock differential or optimizing a high-performance drivetrain. This spacer ensures proper positioning of the pinion gear in relation to the ring gear, which is crucial for achieving smooth gear mesh and minimizing backlash.

The solid pinion spacer works in conjunction with selective shims to achieve the precise preload and depth geometry required for your differential. Unlike adjustable spacer systems, the solid design eliminates slop and flex under load, ensuring consistent performance even in high-torque and racing applications. The included shims allow for exact pinion depth measurements, which are critical for preventing premature gear wear and noise.

Mechanics and drivetrain specialists rely on RATECH pinion spacers for various applications, including street, strip, and track, where the quality of gear mesh directly impacts reliability and performance. Installation requires careful micrometer measurements and shim selection based on the specific differential carrier and ring-and-pinion set. This product is designed to fit standard differential housings, ensuring no adverse effects on drivetrain balance or response.
