Product details
The 6.88-inch lug pattern identifies the attachment layout of this Wilwood AT6 Off-Road. This right-hand red caliper has 6 pistons, 1.75/1.38/1.38-inch bores and a 0.72-inch nominal rotor-width specification. Wilwood Engineering’s disc brake range includes calipers, rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977 in California; it is based in Camarillo and serves motorsport, street-performance and specialized brake applications.
The AT6 six-piston racing caliper was developed for off-road trucks and buggies. A removable bridge gives top access to type 7516 pads, and the 6.88-inch lug pattern must align with the intended race upright or bracket.

Fitment & Compatibility
Measure the available space at both sides of the rotor, including its hat. Confirm mounting geometry and piston area; rotor width by itself cannot establish a complete brake package.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
PMB Performance has worked with parts and brake fitment for over 20 years. Supply the installed caliper identity and the rotor and bracket measurements for a practical compatibility check.
