Differential Gasket Ford 9in 1/32in THICK

The Differential Gasket Ford 9in 1/32in Thick by FEL-PRO (MPN 2301) is a precision-engineered seal designed for Ford 9-inch differentials, one of the most iconic and durable rear axle assemblies in automotive history. This gasket sits between the differential case halves, creating a critical oil-tight seal that prevents gear oil from leaking out and contaminating your brake components or suspension. Whether you're rebuilding a classic muscle car, restoring a vintage truck, or maintaining a high-performance racing differential, this OEM-quality gasket is essential for any differential service or case separation job.

Manufactured from compressed fiber material at a nominal thickness of 1/32 inch (approximately 0.031 inches), this gasket offers reliable compressibility and conformability to irregular case surfaces—critical properties that prevent oil seepage under the cyclic pressure and thermal cycling that differentials experience during operation. FEL-PRO's gasket composition resists gear oil degradation and maintains its sealing integrity across a wide temperature range, from cold starts to sustained highway driving. The compact dimensions (12 x 0.3 x 16.65 inches) reflect the gasket's fit around the Ford 9-inch differential's circular case geometry, ensuring proper alignment during reassembly without excess material that could interfere with internal components or cause installation complications.

Mechanics and differential enthusiasts rebuilding Ford 9-inch rears in Mustangs, F-Series trucks, hot rods, and performance vehicles will find this gasket indispensable for leak-free reassembly. Installation requires cleaning both case halves thoroughly with solvent to remove old gasket material and oil residue, then seating the new gasket dry (without sealant) before torquing the case bolts to specification in a proper sequence. This single-unit gasket prevents costly oil loss and maintains proper differential lubrication, protecting your gears and bearings from premature wear and catastrophic failure during hard acceleration or towing.
