Wilwood Front Right AeroDM Brake Caliper, Anodized, 1.25-Inch Rotor Width for GM 1500 Trucks/SUVs (1999–2018)

Wilwood supplies this front right AeroDM brake caliper for GM 1500 Trucks/SUVs with an anodized finish. Its 7.56-inch mounting span and 1.25-inch-wide rotor configuration are key checks when selecting a single caliper for an existing system. 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. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures disc brake systems and their individual components. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood supplies a range encompassing calipers, rotors, master cylinders, valves, fittings and brake lines, all selected to match the complete system.
