Product details
The rotor and bracket determine whether this black Wilwood AeroDM front right brake caliper for Jeep Wrangler JK is the correct choice. Its 1.25-inch rotor-width configuration works with the lug mount and 6-piston layout detailed below. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement. 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.
