Product details
The 5.75-inch lug attachment distinguishes this front left Wilwood AeroDM brake caliper for Jeep Wrangler JK. This individual anodized unit is built for the 1.25-inch-wide rotor configuration and requires accurate alignment with the mating rotor and bracket. 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. 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.
