Wilwood Front SRP Rotor & Black Caliper Kit for Jeep Wrangler JL / Wrangler / Gladiator (2018–2025)

For Jeep Wrangler JL / Wrangler / Gladiator (2018–2025), this front AERO6-DM kit uses black Wilwood calipers and srp drilled & slotted rotors. Its 6-piston hydraulic layout and 13.38-inch rotor diameter need to be checked against the actual hub, upright and wheel arrangement. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company makes disc-brake systems for street-performance, motorsport and specialized applications. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines are selected around the demands of the complete braking installation.
