Product details
The black left rear Wilwood TX6 carries six stainless pistons for the documented later Ford heavy-duty truck rear brake package. A nominal 1.38-inch rotor channel and 5.04-square-inch effective area identify this configuration separately from the larger-bore front caliper. 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 2023-and-later Ford F-250/F-350 4WD rear conversion's bracket, rotor and flexline arrangement. Check rotor offset and the wheel-clearance drawing, and retain the caliper's proper left-hand piston sequence.
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.
