Wilwood TX6R Left Caliper, Type III Anodized, 1.30–1.38-Inch Width and 9.63-Inch Mount

The Wilwood TX6R shown here is specified for 1.38-inch rotor width, 9.63-inch radial mounting and 1.62/1.38/1.38-inch piston bores. This left-hand Type III anodized 6-piston component is selected by brake-system geometry rather than vehicle year alone. 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

Select pads by the specified friction shape and intended operating temperature. Check the wheel template with the actual rotor, hat and bracket before finalizing the installation.

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