Product details
The XRZ lug-drive kit connects a 46-spline Sprint axle to the specified eight-lug rotor. A snap ring and wear plates retain the rotor without rotor-to-plate bolts; those retention parts are supplied separately. Wilwood Engineering is a Camarillo, California manufacturer founded by Bill Wood in 1977. Disc brake design and manufacturing extend across calipers, brake rotors, master cylinders, valves, fittings and brake lines. Parts for street-performance, specialized applications and motorsport must be selected to meet the requirements of the complete brake system.
