Product details
Match this red 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.
Fitment & Compatibility
Identify the existing mounting bracket and compare its caliper centerline, hole spacing and radial position. Verify the piston configuration against the hydraulic system specification.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
With over 20 years of experience, PMB Performance can help compare piston configuration and mounting geometry. Share the existing brake package and measured rotor dimensions before ordering.
