Product details
Wilwood AeroDM calipers must be matched by width and mounting configuration. This black front left brake caliper for GM 1500 Trucks/SUVs has 1.75/1.62/1.62-inch bore dimensions, a 7.56-inch mounting span and the 1.25-inch-wide rotor specification. 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. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another.
