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 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 rotor mount plate that adds overall strength by eliminating the brake torque loading from the main hub body, by taking the stress loads of the braking torque out of the hub body and moving it to the thicker, stronger section of the hub near the inner wheel bearing, provides a measurable decrease in stress deflection in the body.
The rotor mount plates are configured for both fixed and dynamic rotor mounting by simply changing the bolt kits. With dynamic mount t-nut rotor bolt kits, 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. For less extreme temperature applications, the rotors can be fixed mounted. 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, and all rotor bolt kits must be ordered separately
