Product details
An individual Wilwood AeroDM front right brake caliper for Jeep Wrangler JL/Gladiator JT, finished in red, is specified here. Use the 1.75/1.62/1.62-inch piston bores, 5.75-inch mounting centers and 1.25-inch rotor width to compare it with the existing brake assembly. 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.
