Complete Kit Ford 9in

The RATECH Complete Kit Ford 9in Differential Installation Kit (Part No. 306TK-1) is a comprehensive bearing and seal assembly designed specifically for Ford 9-inch differentials with a 2.891-inch ID case. This complete kit streamlines the differential rebuild process by bundling all essential components—bearings, crush sleeve, gaskets, hardware, seals, and shims—into a single package, eliminating the need to source parts individually and reducing installation errors.

Ford 9-inch differentials are found in a wide range of vehicles, from classic muscle cars to modern hot rods and off-road applications. The 2.891-inch ID case specification denotes the internal diameter of the differential housing, a critical dimension that determines bearing fit and proper preload. RATECH's complete kit includes the precision bearings required for this case size, ensuring correct clearances and eliminating the guesswork of matching components. The inclusion of marking compound allows technicians to verify proper gear contact patterns during setup, a professional-grade practice that prevents premature wear and noise. Properly installed bearings and seals protect the differential fluid from contamination and prevent leakage during high-stress conditions such as heavy acceleration, towing, or sustained off-road use.

This kit is designed for owners and technicians performing differential maintenance, rebuilds, or upgrades on Ford 9-inch equipped vehicles. Whether restoring a classic vehicle, upgrading a performance car, or maintaining an off-road platform, having all components matched to the exact case size eliminates compatibility issues and reduces assembly time. The kit weighs 4.85 pounds and ships in compact dimensions, making it convenient for both professional shop use and DIY installations. Technicians familiar with Ford 9-inch differential service will recognize the value of a complete, matched component set that ensures bearing preload, seal integrity, and long-term reliability.
