6.50 Ford 9in Pro Gear 28 Spline

The Richmond 6.50 Ford 9-inch Pro Gear 28 Spline ring and pinion kit delivers the gear ratio control needed for high-performance axle builds and off-road recovery applications. This 6.50 ratio setup is engineered for Ford 9-inch differentials and represents a proven choice for operators and enthusiasts who demand precision-matched gearing in critical power transmission scenarios.

The 28-spline pinion design ensures solid engagement with modern Ford 9-inch carrier systems, a critical factor when running aggressive torque loads during towing, off-road recovery, or high-speed highway operation. The 6.50 ratio sits in the mid-range for Ford 9-inch applications—taller than 7.00 but lower than 5.89—making it versatile across multiple vehicle configurations. Richmond's Pro Gear line is manufactured to close tolerances, minimizing backlash and extending component life in high-stress environments. The complete kit format simplifies installation by providing matched ring and pinion as a single assembly, reducing the chance of incompatible parts reaching the field.

This gearset serves users operating vehicles in patrol, pursuit, or recovery roles where differential performance directly impacts safety and mission capability. Heavy-duty truck owners, off-road expedition teams, and performance enthusiasts value the 6.50 ratio for balancing acceleration response with cruising efficiency. Whether you are rebuilding a worn differential or upgrading for higher torque capacity, the Richmond Pro Gear 28-spline kit provides the core components needed for a dependable axle assembly.

Weighing 20.32 lbs, this kit is compact enough for direct installation into standard Ford 9-inch housings. Always verify your existing carrier and pinion shaft spline count before ordering to confirm compatibility with your specific differential assembly.
