Wilwood TX6R Left Brake Caliper, Type III Anodized / 2.00/1.88/1.88-Inch Bore / 1.38-Inch Rotor Width

A 6-piston Wilwood TX6R for left-hand installation, this Type III anodized caliper works around a nominally 1.38-inch-wide rotor. Its 2.00/1.88/1.88-inch bore configuration and 9.63-inch radial centers are the principal dimensions to compare. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Confirm rotor diameter as well as thickness, and allow for pad and caliper clearance inside the wheel. The mount pattern is a dimensional requirement rather than a vehicle fitment guarantee.

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

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.
