9in Ford Housing Seal Red

The 9in Ford Housing Seal Red from ALLSTAR PERFORMANCE is a precision-engineered axle housing seal designed for serious enthusiasts and professional mechanics rebuilding or upgrading Ford 9-inch differentials. This inner O-ring seal prevents gear oil leakage at the critical interface where the axle tube meets the differential housing, maintaining proper lubrication and preventing contamination that can compromise bearing life and differential performance. Whether you're restoring a classic muscle car, building a high-performance street machine, or maintaining fleet vehicles, this seal is essential for reliable differential operation.

Constructed from red anodized aluminum with integrated rubber O-ring technology, the 9in Ford Housing Seal Red features a 2.625-inch outer diameter and 1.125-inch inner diameter with a 0.188-inch thickness, engineered to fit 3/16-inch wall 3-inch axle tubes found in Ford 9-inch housings. The aluminum/rubber composite design provides superior sealing integrity under both street and racing conditions, resisting oil degradation and thermal cycling that can compromise inferior seals. The red anodized finish offers corrosion resistance and provides visual identification during assembly, reducing installation errors on the workbench.

This seal is indispensable for anyone performing differential maintenance, gear changes, or axle bearing service on Ford 9-inch applications—from vintage hot rods and muscle cars to modern performance vehicles featuring Ford solid-axle platforms. Proper installation requires careful cleaning of mating surfaces and correct orientation of the O-ring to ensure full contact with both the aluminum housing and axle tube. Mechanics and enthusiasts trust ALLSTAR PERFORMANCE's attention to dimensional accuracy and material quality to eliminate leaks and extend differential service life.
