Aluminum Seal

The Aluminum Seal from Winters Performance is a precision-engineered component designed for high-performance axle assemblies where fluid containment is critical. This inner axle housing seal serves as a vital barrier, preventing gear oil from migrating through the axle tube during intense racing conditions or heavy-duty use. For builders and racers looking for a reliable solution to maintain drivetrain integrity, this component offers a professional-grade fit for custom rear-end setups. It ensures that lubricants stay where they are needed most, protecting expensive internal components from premature wear.

Constructed from high-grade aluminum, this Aluminum Seal features a gold anodized finish that provides superior resistance to corrosion and wear in harsh racing environments. The seal incorporates a specialized O-ring design to create a secure, leak-proof interface between the housing and the axle shaft. With an outer diameter of 2.525 inches and an inner diameter of 1.19 inches, the unit is machined to exacting tolerances to ensure a tight press fit within the housing. The 1.625-inch thickness provides ample surface area for stability within the tube, preventing the seal from shifting under mechanical stress or vibration.

This specific Aluminum Seal is optimized for use with 2.500-inch internal diameter aluminum axle tubes, making it a staple for sprint cars and other competitive racing platforms. Whether you are performing a routine maintenance overhaul or building a new rear-end from scratch, this seal provides the technical specifications required for professional applications. Each unit is sold individually, allowing for precise inventory management when servicing multi-axle setups or individual housing ends. Installing these seals is a standard procedure for any team prioritizing drivetrain longevity and consistent performance on the track.
