Product details
For a brake assembly requiring the 1.25-inch rotor-width version, this Wilwood AeroDM front left brake caliper for Jeep Wrangler JK provides the red configuration. Compare its lug mount and piston area with the component being replaced. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another. 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.
