Product details
Check the 7.56-inch mounting centers before fitting this anodized Wilwood AeroDM front left brake caliper for GM 1500 Trucks/SUVs. The component is sold individually and uses 1.75/1.62/1.62-inch bores in its 1.25-inch rotor-width configuration. 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. Based in Camarillo, California, Wilwood Engineering has its origins in the company Bill Wood founded in 1977. Its designs and manufactured disc brake products cover calipers and rotors alongside master cylinders, valves, fittings and lines. Motorsport, street-performance and specialized installations each require components selected for the complete system.
