Product details
A nominal 1.25-inch rotor channel pairs with the larger 4.86-square-inch piston area on this anodized Wilwood XRS6R. Its right-hand body uses six stainless pistons, with differential sizes that must follow the intended direction of rotor travel. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems for motorsport, street-performance and specialized use, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Check the rotor against the 1.19–1.25-inch width limits and confirm its friction diameter with the radial bracket. Retain the hydraulic design's intended effective piston area when replacing a caliper in an existing installation.
