Product details

For a brake system using a 1.38-inch-wide rotor, this red Wilwood TX6R provides 6 pistons with 1.75/1.62/1.62-inch bores. Right-hand mounting is specified. The caliper attaches on 9.63-inch radial centers. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.

The TX6R is a six-piston radial-mount caliper developed for heavy truck, SUV and specialized severe-duty brake systems. Type 10120 pads provide its large friction package; installation still requires a matching rotor, bracket and hydraulic design.

Fitment & Compatibility

Measure rotor width before comparing calipers. Verify the mount height, rotor centerline and available wheel space; a common piston count does not establish interchangeability.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.

With over 20 years of experience, PMB Performance can help compare piston configuration and mounting geometry. Share the existing brake package and measured rotor dimensions before ordering.
