Product details
Wilwood AeroDM calipers must be matched by width and mounting configuration. This anodized front right brake caliper for Jeep Wrangler JL/Gladiator JT has 1.75/1.62/1.62-inch bore dimensions, a 5.75-inch mounting span and the 1.25-inch-wide rotor specification. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures disc brake systems and their individual components. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood supplies a range encompassing calipers, rotors, master cylinders, valves, fittings and brake lines, all selected to match the complete 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.
