Product details
An individual Wilwood AeroDM front right brake caliper for GM 1500 Trucks/SUVs, finished in anodized, is specified here. Use the 1.75/1.62/1.62-inch piston bores, 7.56-inch mounting centers and 1.25-inch rotor width to compare it with the existing brake assembly. 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. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking system.
