Wilwood Rear Drag Rotor-to-Hat Hardware, Eight 5/16-18 Hex Bolts

For a compatible rear drag rotor and threaded hat, this kit uses eight Grade 8 hex-head bolts with a 0.750-inch length. Wilwood identifies this short-profile hardware for assemblies where the rotor-to-hat bolt-head clearance must be controlled. Camarillo, California is home to Wilwood Engineering, the disc brake manufacturer Bill Wood founded in 1977. Wilwood designs and manufactures systems and components including calipers, rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized applications require parts selected for the complete brake system's demands.
