Lock Washer for 2.5in GN 5x5 Hub

The Lock Washer for 2.5in GN 5x5 Hub is a precision retention component designed for use in Grand National spindle assemblies and high-performance racing applications. This tab-style lock washer is essential for preventing fastener rotation and loosening under vibration, making it critical for drag racing, circle track, and street performance builds where wheel security is paramount.

Manufactured by Diversified Machine under the CRC-2006 specification, this lock washer features a robust design that mechanically locks against the spindle nut grooves, creating a positive anti-rotation barrier. Constructed from hardened steel, it offers superior corrosion resistance compared to aluminum or composite alternatives, ensuring longevity in various climate conditions and exposure to road salt.

Racers, fabricators, and performance suspension builders rely on this component for five-lug Grand National wheel hubs, where fastener failure could lead to catastrophic wheel separation. Its straightforward installation process allows for easy positioning against the Grand National spindle nut, maximizing contact surface and load distribution for optimal performance.
