Product details
A red forged TX6-DM housing supports the six dust-booted pistons in this right front Wilwood caliper. The selected mounting pattern is 11.22 inches, used for the documented 2011–2019 GM 2500/3500 brake conversion rather than the later truck arrangement. 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.

Fitment & Compatibility
Use the matched Wilwood 15.00-inch-diameter rotor with 1.50-inch width package and line fittings for the truck. The exact spindle interface, pad contact track and wheel clearance all need verification when replacing an individual caliper.
With 20+ years of experience, PMB Performance can help assess the brake hardware. Provide the caliper number, rotor dimensions and bracket measurements when asking about compatibility.
