Product details
For a brake system using a 1.50-inch-wide rotor, this black Wilwood TX6R provides 6 pistons with 2.00/1.88/1.88-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
Check pad depth against the rotor’s usable friction annulus. Rotor-hat clearance, mounting offset and the wheel’s inner profile must also be checked with the caliper drawing.
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.
