Half Scale Dragster Tru-Spin rear axle assemblies are built of one-piece billet aluminum, and include an integral sprocket hub and rotor hub mount, splined wheel hubs, and 70/75 T-6 splined aluminum rear axle (rear wheels and sprocket sold separately). The Tru-Spin assembly is set apart from a keyed rear axle because the sprocket hub and rotor hub are part of the axle—meaning the rear axle can never shift or slip. The ends of the axle are splined, allowing for a better distribution of power to the wheels, and a steel rotor is also included. This setup is recommended for anyone running in the 7.90 range.
