Product details
A 6-piston Wilwood TC6R for left-hand installation, this red caliper works around a nominally 1.38-inch-wide rotor. Its 1.88/1.62/1.62-inch bore configuration and 8.27-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.
Wilwood specifies front mount clocking for this left-hand caliper. This is its orientation around the spindle, not a designation of the vehicle’s front or rear axle. Match the intended rotor rotation and upper bleed position.

TC6R calipers use six differential-bore stainless pistons in a radial-mount body intended for heavy truck and SUV brake packages. Six bridge bolts join the body, and replaceable steel bridge plates protect the pad abutments.
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.
For a brake system assembled from individual components, PMB Performance brings over 20 years of experience. Contact us with the rotor, caliper and bracket information so we can help check the combination.
