Ford 9in Axle Tube Seal Alum. Red w Seal & Oring

The Ford 9in Axle Tube Seal Alum. Red w Seal & Oring is a precision inner axle housing seal designed for Ford 9-inch differential applications. This seal kit is essential for builders and mechanics who need to maintain reliable axle integrity and prevent fluid leakage in high-performance or heavily-modified differentials. Whether you're rebuilding a classic hot rod, upgrading a truck's drivetrain, or servicing an existing 9-inch rear end, this complete seal assembly delivers the OEM-quality fit and durability required for long-term reliability.

Manufactured by PEM, this kit features a red anodized aluminum housing seal with integrated O-ring and complementary seal components. The seal is engineered to work with a 2.625-inch outer diameter and accommodates a 1.125-inch inner diameter, providing a precise fit for 2.600-inch ID steel axle tubes common in Ford 9-inch differentials. The 0.188-inch thickness ensures proper compression and sealing integrity under demanding conditions, while the aluminum construction with anodized finish resists corrosion and wear. The included O-ring creates a secondary seal layer, reducing the risk of differential fluid seepage and protecting bearing surfaces from contamination.

This axle tube seal kit is ideal for anyone performing differential rebuilds, axle shaft replacement, or preventive maintenance on Ford 9-inch rear ends used in street cars, race vehicles, and light-duty trucks. Installation requires standard differential tear-down procedures and familiarity with axle assembly. The complete kit (PEMF9AXTS3Kit) includes all necessary sealing components, eliminating the need for separate purchases and ensuring compatibility across your rebuild. Compact and lightweight at 0.4 lbs, the kit fits easily into a toolbox and is ready for immediate installation when your project demands superior axle sealing performance.
