Product details
A black powder-coated XRS6R housing contains six stainless pistons in this right-hand Wilwood caliper. The larger 4.86-square-inch effective area accompanies a nominal 1.10-inch rotor-width channel, distinguishing it from smaller-bore members of the same family. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977; its motorsport, street-performance and specialized range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Confirm an actual rotor width within 1.00–1.10 inches and its offset relative to the bracket. Check the wheel barrel around the caliper body and ensure the chosen inlet fitting clears adjacent hardware.
