Product details
A 1.25-inch rotor-width specification and 1.75/1.62/1.62-inch piston bores identify this front right Wilwood AeroDM brake caliper for GM 1500 Trucks/SUVs. The black finish is applied to the exact component described below; match the mounting bracket before replacement. 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.
