Product details
Wilwood supplies this front right AeroDM brake caliper for Jeep Wrangler JK with a red finish. Its 5.75-inch mounting span and 1.25-inch-wide rotor configuration are key checks when selecting a single caliper for an existing system. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Components must be selected to suit the complete brake 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.
