Gasket - Ford 9in Center Section

The Strange Gasket for Ford 9-inch Center Section (H1111S) is an OEM-specification replacement seal designed for high-performance differentials and drag racing applications. It is essential for those who are rebuilding a stock 9-inch rear end or maintaining a modified differential housing. This gasket acts as a critical barrier between the center section cover and the main housing, effectively preventing gear oil seepage and maintaining system integrity under load.

Manufactured from premium composite material, this gasket is engineered to withstand shock loads, thermal cycling, and high-pressure conditions typical of performance differentials. Its engineered thickness and sealing surface geometry ensure a consistently leak-free installation across repeated assembly cycles, which is crucial for custom-built or race-prepared rear axles. Strange Engineering's rigorous manufacturing process guarantees flatness and material consistency, preventing premature degradation from gear oil exposure or vibration-induced separation.

This replacement gasket is ideal for differential rebuilds and post-service maintenance, making it suitable for street, strip, or competition environments. Anyone running a Ford 9-inch rear end will benefit from the reliability and performance this gasket provides. Its design allows for seamless integration with all 9-inch center section configurations, ensuring no clearance issues arise during installation.
