Product details
The 7.56-inch lug attachment distinguishes this front right Wilwood AeroDM brake caliper for GM 1500 Trucks/SUVs. This individual black unit is built for the 1.25-inch-wide rotor configuration and requires accurate alignment with the mating rotor and bracket. AeroDM is a forged six-piston caliper using a vehicle-specific direct lug mount. It is intended for the matching Wilwood rotor and conversion geometry, rather than the stock rotor by itself. Verify the package, side and lug offset before ordering a replacement. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Components must be selected to suit the complete brake system.
