Side Bell Seal Open Tube

The Side Bell Seal Open Tube is an essential maintenance component designed for high-performance rear-end assemblies, specifically those utilizing the Winters open tube side bell configuration. This inner lip seal serves as a critical barrier, ensuring that gear lubricants remain contained within the differential housing while preventing external debris from compromising internal gears. Racers and automotive technicians rely on this specific seal to maintain the integrity of their drivetrain during high-stress competition or rigorous track use.

Constructed from a durable combination of rubber and steel, the Side Bell Seal Open Tube is engineered to withstand the thermal demands and rotational friction inherent in racing environments. With a 4.125-inch outer diameter and a 2.938-inch inner diameter, this component provides a precision fit that effectively seals the interface between moving parts. The 0.375-inch thickness ensures a robust sealing surface that resists deformation, while the steel reinforcement provides the necessary structural rigidity for a secure press-fit installation.

This seal is specifically designed for use with Winters Open Tube Side Bells, making it a vital part for those looking to buy reliable replacement components for their existing quick-change setups. Proper installation of the Side Bell Seal Open Tube is necessary to prevent oil leaks that could lead to catastrophic gear failure or loss of traction on the track. Whether you are performing a routine rebuild or addressing a leak during a race weekend, this component provides the exact specifications required for a professional-grade repair.
