Eaton Detroit Locker Diff 31 Spline 1.32in Shaft Dia (Excl 2.72 Ratio) Ford 9in Circle Track w/Case

This Eaton Detroit Locker differential is designed specifically for Ford 9-inch rear ends used in circle track racing applications. What you get is a complete differential unit, ready to be installed into your existing Ford 9-inch housing. This locker is built to keep both rear wheels driving, even if one tire loses contact with the track surface, ensuring you maintain maximum traction when you need it most. It's a 100% automatic locking unit, meaning it engages without any input from the driver, working seamlessly in both forward and reverse directions.

The strength of the Detroit Locker comes from its unique, bullet-proof design. It's a clutchless system, which means it's maintenance-free and doesn't require periodic adjustments or fluid changes related to clutch packs. This particular model is for 31-spline axles with a 1.32-inch shaft diameter and excludes the 2.72 ring and pinion ratio. Its robust construction is intended to handle the demands of circle track racing, providing consistent and reliable performance lap after lap.

When setting up this differential, ensure you follow the manufacturer's installation instructions carefully, especially regarding gear setup and bearing preloads for your specific Ford 9-inch housing. Because this is a full locker, expect a noticeable change in steering characteristics on the street or in low-speed maneuvers; it's optimized for racing conditions where consistent traction is paramount.
