Richmond Gear: American-Made Drivetrain Expertise

For decades, Richmond Gear has been one of the most respected names in American drivetrain performance. Founded in Richmond, Indiana, the company built its reputation on precision-engineered gear sets designed to handle everything from daily street driving to the rigors of off-road trails and competitive racing. Whether you are restoring a classic muscle car, building a rock crawler, or pushing a performance truck to its limits, Richmond Gear delivers the gear-cutting quality and metallurgical consistency that serious builders demand.

The Gold Standard in Ring and Pinion

Richmond Gear's core expertise lies in differential ring and pinion gear sets — the heart of any axle assembly. Richmond manufactures ring and pinion sets to exacting tolerances, using high-quality steel alloys and advanced heat-treating processes to produce gears that mesh smoothly, run quietly, and hold up under sustained load. Their broad ratio selection covers everything from economy-minded highway gearing to steep off-road ratios, making it easy to find the right gear for virtually any application. This depth of coverage across domestic and import axle families is a big reason why professional builders and serious enthusiasts consistently reach for Richmond.

Complete Differential Build Solutions

Richmond Gear understands that a great ring and pinion is only as good as the supporting components around it. That is why they also offer differential bearing kits engineered to complement their gear sets, providing the precise preload and durability needed for a long-lasting differential build. For applications that call for maximum traction — such as drag racing or rock crawling — Richmond's differential spools offer a solid, reliable solution that eliminates the complexity of a traditional open or limited-slip carrier.

Proper gear installation is a craft, and Richmond supports the installer every step of the way. Their gear marking compound is an essential setup tool, allowing builders to accurately read gear contact patterns and fine-tune backlash before final assembly. Combined with their differential gear install kits — which bundle the shims, crush sleeves, and hardware needed for a complete job — Richmond makes it straightforward to do the work right the first time.
