Hub Seal 5x5 2.5in Pin Low Drag

The Allstar Performance Hub Seal 5x5 2.5 inch pin low drag bearing seal is a purpose-engineered inner lip seal designed for high-performance rear axle assemblies on 5x5 bolt pattern racing hubs. This seal minimizes rotational drag while maintaining reliable sealing, making it essential for competitive drag racing, circle track, and street performance applications where reduced friction translates directly to faster acceleration and improved fuel economy.

The seal features a 3.75-inch outer diameter with a 3-inch inner bore and 0.32-inch thickness, manufactured from a rubber-steel composite construction. This design reduces bearing preload and rotational resistance compared to standard seals, a critical advantage in drag racing where every fraction of a second counts. The low-drag geometry maintains an effective barrier against grease loss and contamination while allowing wheels to spin more freely, improving quarter-mile times and reducing heat buildup during extended track sessions.

This seal is compatible with popular 2.5-inch pin 5x5 hub systems used by AFCO, Allstar, SCP, and Winters racing components, making it a direct replacement for OEM and upgrade applications. Racers upgrading from standard seals to low-drag versions typically notice improved launch characteristics and reduced tire spin, as freed-up wheel rotation allows traction control systems to work more effectively. The seal is sold as a single unit, so verify whether your application requires one or a full set before ordering.
