Safety hubs, which were originated by Strange Engineering, are required by drag racing rules for good reason. C-clip type axles are retained by a clip above the spline portion of the axles. When the stock axle or differential breaks, the entire axle/brake/wheel assembly can slide completely out of the housing. Strange's safety hubs eliminate wheel loss and worn bearing areas. The bearings are retained and the axles are held securely in place by the safety hubs, which are bolted to the stock axle housing through the existing backing plate holes.
