Differential Cover Kit Dana 60/70 9.75 Rear

The Specialty Products Company Differential Cover Kit Dana 60/70 9.75 Rear (Part No. 4910XKIT) is a complete aluminum differential cover assembly designed for heavy-duty truck and off-road applications. This kit provides sealed protection for your rear differential against water intrusion, debris, and contaminants—critical safeguards when operating in harsh marine, coastal, or remote terrain environments where corrosion and moisture are constant threats to drivetrain integrity.

The kit includes the aluminum cover housing, a precision gasket, and all necessary hardware for installation on Dana 60, Dana 70, and 9.75-inch rear differentials. Aluminum construction offers a balance of weight savings and corrosion resistance compared to cast iron, making it ideal for salt-air environments or vehicles regularly exposed to water crossings. The gasket is pre-fitted to ensure a tight seal on first installation, reducing the risk of improper seating and subsequent leaks. Measured at 4.75 lbs, this cover is lighter than OEM cast alternatives while maintaining structural rigidity under load.

This differential cover kit addresses a fundamental maintenance need for serious boaters, off-road adventurers, and truck owners who operate in moisture-rich or high-temperature conditions. Whether you're running a boat trailer truck through coastal terrain, towing across salt marshes, or tackling recovery operations where water crossings are unavoidable, a sealed differential cover prevents rust formation on internal gear surfaces and extends drivetrain service life. The natural aluminum finish allows for easy inspection of surface conditions and accepts protective coatings if additional corrosion resistance is desired. Installation is straightforward for users with basic mechanical skills and standard socket tools.
