Return PolicyThe Speedway Motors 91910031 Ford 9 Inch Limited-Slip Differential Rebuild Kit combines the key components needed to upgrade or rebuild a Ford 9-inch rear end into one convenient package. This kit includes a Motive Gear performance ring and pinion set, a 31-spline clutch-style limited-slip differential, and a complete overhaul kit with the bearings, seals, shims, hardware, and installation components required for proper setup.
Designed for street, performance, and racing applications, the kit provides improved traction through a clutch-style limited-slip carrier while allowing customers to tailor performance with a choice of gear ratios. Available ratios include 3.00, 3.25, 3.50, 3.70, 3.89, 4.11, and 4.56, making it easy to optimize acceleration, top-speed characteristics, or overall drivability for specific vehicle setups.
The included Motive Gear ring and pinion is manufactured for strength and durability, while the 31-spline clutch-style differential offers smooth, quiet limited-slip operation without the harsh engagement characteristics of a spool or locker. Completing the package, the overhaul kit provides the critical bearings, seals, crush sleeve, shims, sealant, and setup materials needed to streamline installation and ensure reliable performance.
