Product details
The black right front TX6-DM is a Wilwood six-piston component for the 2011–2019 GM heavy-duty truck brake arrangement. Its 2.00/1.88/1.88-inch stainless pistons and 11.22-inch direct-lug centers distinguish the configuration from the later GM spindle version. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.
