4.86 Ford 9in Pro Gear 28 Spline

The Richmond 4.86 Ford 9-inch Pro Gear 28 Spline ring and pinion kit is a high-performance differential gear set designed for serious off-road and high-torque applications. This complete kit is perfect for 4x4 recovery operations, heavy-duty towing, and off-road enthusiasts who require maximum crawling capability and quick responsiveness in challenging terrain.

The 4.86 ratio is a numerically high gear set that reduces wheel speed relative to engine RPM, enhancing torque output at the wheels while sacrificing top-end highway speed. The 28-spline small pinion design is built for durability under heavy loads, and the Pro Gear line from Richmond ensures precision manufacturing and reliability under sustained stress.

This configuration is particularly suited for vehicles operating at low speeds with maximum load, making it ideal for technical rock crawling and industrial applications where torque multiplication is prioritized over fuel economy. Buyers should verify compatibility with their specific 9-inch housing variant and consult appropriate service documentation for installation procedures.
