This Wilwood AERO6-DM front brake kit pairs red 6-piston calipers with 13.38-inch gt slotted brake rotors for Jeep Wrangler / Wrangler JK (2007–2018). The package must match the documented mounting arrangement and wheel clearance before the original brakes are removed. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. Its disc-brake systems and components serve motorsport, street-performance and specialized applications. The range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to suit the requirements of the complete system.

Fitment & Compatibility

The 2007–2017 Jeep Wrangler and 2018 Wrangler JK rows below refer to the JK generation, not the later JL. DS1550 uses the factory front upright and hub with the JK-specific hydraulic piston sizes and included 22-inch flexlines. Verify hose travel at full steering lock and suspension articulation, and check the complete 17-inch wheel-clearance drawing. Use the fitment table below to check the complete application and option notes.

A VIN helps identify the original specification; measured hardware matters after a conversion. PMB Performance draws on more than 20 years of experience when reviewing those details.
