Product details
The anodized front right Wilwood AeroDM for Jeep Wrangler JK is an individual brake caliper. It combines a 5.75-inch attachment span with 1.75/1.38/1.38-inch piston bores; confirm the rotor centerline and 1.25-inch width configuration before installation. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole 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.
