Bearing and Race 2-7/8 Wide 5 (Single)

The Bearing and Race 2-7/8 Wide 5 (Single) by Winters is a precision roller bearing assembly engineered for high-performance automotive applications where axle loads demand reliable, repeatable support. This single unit serves mechanics and drag racing enthusiasts who rebuild or modify differential assemblies, demanding consistent load distribution and minimal radial play. Whether you're restoring a vintage hot rod, upgrading a competition vehicle, or repairing a worn differential, this bearing and race set delivers the durability and precision fit required for safe, efficient power transfer.

Constructed from hardened steel, the Winters bearing and race assembly features a 2-7/8-inch width profile specifically designed for Wide 5 bolt patterns—a standard found in many classic and custom rear axle housings. The roller bearing design distributes axle loads across multiple contact points, reducing stress concentration and extending service life under sustained acceleration or cornering loads. The precision-ground race surface ensures minimal runout, critical for maintaining differential geometry and preventing vibration or premature wear on adjacent components. At 0.83 lbs, this single bearing unit integrates seamlessly into matched pairs for complete differential support.

Technicians and fabricators rebuilding Winters differentials or compatible wide 5 axle assemblies will find this bearing essential for proper preload adjustment and centering. Installation requires careful seating against the race shoulder and correct preload specification to prevent excess play or binding. This single bearing is typically paired with its matching component to complete the differential carrier support system; verify your specific axle model and bearing configuration before ordering to ensure correct fitment and performance. Ideal for off-road, drag, road course, or street applications where bearing integrity directly impacts reliability and handling.
