Product details
This black Wilwood AeroDM front left brake caliper for Jeep Wrangler JK uses a 5.75-inch lug mount and the 1.25-inch rotor-width configuration. It is sold as one caliper, with its piston and mounting specification selected for the complete brake assembly. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking 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.
