Seal Axle Tube

The Frankland Racing Seal Axle Tube (QC0300) is an inner axle housing seal engineered for quick-change rear end systems. This seal assembly features a 2.625-inch outer diameter with a 1.985-inch inner diameter and 0.65-inch thickness, combining rubber and steel construction to contain differential fluid while minimizing rotational resistance. Built for the Frankland Superlite quick-change platform, this seal delivers the precision fit and durability required in high-performance racing applications where gear oil retention and bearing protection are critical.

The lip-design seal creates a positive contact surface against the rotating shaft, preventing fluid migration while accommodating the thermal expansion cycles inherent to racing environments. The rubber-to-steel construction provides resilience against pressure fluctuations and maintains elasticity across wide temperature ranges—essential for drivers pushing gear oil temperatures beyond street-use parameters. At 0.06 pounds, the seal's compact profile integrates seamlessly into the quick-change assembly without adding unnecessary rotating mass to the drivetrain.

This seal is designed for bracket racers, off-road competitors, and track enthusiasts who operate Frankland Superlite quick-change housings. Quick-change rear ends are standard in drag racing, circle track, and performance off-road setups where rapid gear ratio changes between rounds require accessible, modular construction. The seal's precise dimensional tolerances ensure compatibility with the quick-change spline interface, preventing gear oil weepage that could compromise differential function or contaminate the vehicle's chassis. Replacement seals are necessary maintenance items as part of periodic quick-change servicing or after extended high-RPM operation.
