Race Wide 5 Outer

The Race Wide 5 Outer wheel bearing race is a precision-engineered steel component designed for high-performance racing applications, particularly classic and vintage drag racing platforms that utilize wide 5 hub assemblies. Built to exact tolerances, this outer race serves as the critical rolling surface for wheel bearings under extreme lateral and vertical loads. Whether you're restoring a vintage hot rod, building a competition drag car, or maintaining a classic muscle machine, this bearing race is essential for safe, reliable wheel operation at racing speeds.

Constructed from hardened steel and manufactured to ALLSTAR PERFORMANCE standards, the Race Wide 5 Outer is engineered to work in tandem with matching inner races and rolling elements to distribute and support dynamic loads with minimal friction. The wide 5 configuration references the classic five-lug bolt pattern common on early American performance vehicles, and the outer race profile is precision-ground to maintain concentric geometry and consistent load distribution. At just 0.31 lbs and measuring 4 x 0.6 x 7 inches, this compact component fits within tight hub assemblies while providing the durability needed for sustained high-speed operation, frequent cornering, and the thermal cycling experienced in competition environments.

Racers and restoration specialists benefit most from this outer race when rebuilding complete wheel bearing assemblies on wide 5 hubs, ensuring optimal wheel play adjustment and extending bearing service life. Installation requires proper bearing adjustment using dial indicators or feeler gauges to achieve the correct preload—typically 0.001 to 0.005 inches of end play—which maximizes contact pressure between rolling elements and races while minimizing friction. Compatibility is limited to wide 5 hub applications; verify your hub configuration before ordering. This is a single outer race; pair it with the corresponding inner race, ball or roller elements, and seals to complete a full bearing assembly.
