Wilwood 270-17461C Features:

Starlite 55-XD hubs elevate performance and versatility for racing applications that require uncompromised strength without excessive additional weight. At just over 7 pounds, the 55-XD Lug Drive achieves it superior strength and modest weight through a highly efficient redesign of racing’s most popular wide 5 hub, the Starlight 55. The 55-XD employs a bolt-on Lug Drive rotor mounting plate that adds overall strength by eliminating the brake torque loading from the main hub body and adding benefits of Dynamic lug mounting rotors for less temperature induced deflection. The rotor mount plates are configured dynamic lug mounting with wear plates and snap ring. This alleviates stresses from the dissimilar thermal expansion rates of the iron rotor and the aluminum mount are fully isolated from the hub body, and the rotor mount plate as well. All 55-XD hubs feature our black e-coat finish to seal the castings and preserve their good Looks. Rotor mount plates, and the bolts to attach the plate to the hub, are included with all hubs. Front hubs include Snap Cap dust covers. Rear drive flanges, bolt-on dust caps to use a rear hub in a front location must be ordered separately.
