Product details

For the 2013–2018 Ram 1500 Aero6-DM conversion, this is the black right front six-piston caliper. Internal fluid passages connect its opposing piston banks, and a 5.91-inch direct-lug pattern locates the forged body on the compatible spindle. Keeping the specified 6.52-square-inch effective area matters when replacing just one component in an established brake setup. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc braking systems for motorsport, street-performance and specialized applications, with a component range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines.
