The Pinion Nut Ford by RATECH (MPN 1502) is a critical fastener engineered for Ford rear differential assembly and maintenance. This heavy-duty component secures the pinion gear to the differential carrier, preventing axial movement and ensuring proper gear mesh alignment under load. Whether you're rebuilding a worn differential, upgrading to performance gearing, or servicing factory equipment, the pinion nut is essential for achieving a solid, reliable drivetrain.
Manufactured from hardened steel with black paint finish, this pinion nut features a 3/4-20 thread pitch and is purpose-built for Ford 7.25, 7.5, 8, 8.8, and 9-inch differentials. The robust construction resists vibration loosening and fatigue failure, critical when handling torque loads in street, track, or off-road environments. Proper torque specification and preload adjustment during installation directly affect differential noise, longevity, and power delivery—making fastener quality non-negotiable for any serious rebuild.
Mechanics and enthusiasts tackling Ford differential service across Mustangs, Broncos, Rangers, and F-Series trucks rely on RATECH pinion nuts to maintain OEM compatibility and structural integrity. Installation requires a torque wrench, crush sleeve or shim setup, and proper preload procedure—steps that demand the right components. This single nut is supplied per unit, so verify your differential type and have a complete rebuild kit on hand before beginning work.
