Richmond Gear Differential Pinion Bearing Spacer

Richmond Gear Differential Pinion Bearing Spacers: Solid Performance, Built to Last

When rebuilding or upgrading a differential, one of the most overlooked yet critical components is the pinion bearing spacer. The factory crush sleeve that comes in most differentials is a one-time-use part — once it's compressed to set pinion bearing preload, it can never be reused. That means every time you remove the pinion to replace a seal or disassemble the carrier, you're also on the hook for a new crush sleeve. Richmond Gear solves this problem with their line of differential pinion bearing spacers, engineered as a direct, performance-minded replacement for stock crush sleeves.

Solid Steel Construction for Reusability and Reliability

Richmond Gear's solid pinion bearing spacers are manufactured from steel and designed to be reused whenever the differential is serviced. These reusable steel spacers replace stock crush sleeves and help eliminate pinion bearing failure. Unlike a crush sleeve, which deforms under load and can allow bearing preload to shift over time, a solid spacer maintains a consistent, precise fit — a particularly important characteristic in high-stress driving situations.

Unlike traditional crush spacers, Richmond Solid Pinion Bearing Spacers let you easily change your pinion seal or remove your pinion without having to torque a new crush sleeve. For builders who regularly service their differentials — whether for track prep, off-road use, or routine maintenance — this reusability translates directly into saved time and money over the life of the drivetrain.

Spacer and Shim Kits for Complete Installation

Richmond Gear also offers pinion bearing spacer and shim kits for builders who want a comprehensive solution. Richmond Gear pinion bearing spacer and shim kits are great for installing ring and pinion gear sets, and they include a solid spacer that can be reused if you need to take apart and reassemble the carrier. The included shims allow for fine-tuned preload adjustment, giving professional installers and experienced DIYers alike the precision they need to get the job done right the first time.

Richmond's spacer kits cover a broad range of popular differential platforms. Applications include Ford 7.5", 8.8", and 9" differentials, with fitment also available for GM 12-bolt and other configurations. Coverage extends to platforms found in performance vehicles such as the Dodge Challenger, Dodge Charger, Chrysler 300, and others — making Richmond a go-to source for muscle car and enthusiast builds.

Backed by a Brand That Knows Drivetrain Performance

For over 80 years, the Double Diamond has signified the highest quality gears in the racing industry, with Richmond's superior quality being a result of continual research and development, outstanding design, and state-of-the-art manufacturing. That same engineering philosophy carries over into their differential accessories. Richmond's commitment to quality is backed by strong warranty coverage, with performance products warranted against defects for a period of two years under normal driving conditions.

Whether you're refreshing a worn differential, completing a ring-and-pinion swap, or building a track-ready axle from scratch, Richmond Gear's solid pinion bearing spacers provide a reliable, professional-grade foundation.
