Product details
Match this black Wilwood AT6 Off-Road to a brake assembly requiring 0.72-inch rotor width and 1.75/1.38/1.38-inch pistons. The left-hand 6-piston caliper uses 6.88-inch lug mounting rather than a vehicle-specific adapter supplied as a kit. 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.
