Product details
The anodized left front Wilwood TX6-DM is selected for the GM 2500/3500 heavy-duty conversion beginning with the documented 2020 application. Its six-piston body uses 2.00/1.88/1.88-inch differential bores and a nominal 1.50-inch rotor channel. 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.

Fitment & Compatibility
