Wilwood Front 13.38-Inch Drilled Rotor & Black AERO6-DM Caliper Kit, Jeep Wrangler / Wrangler JK (2007–2018)

Wilwood configures this front AERO6-DM kit around 13.38 × 1.25-inch rotors for Jeep Wrangler / Wrangler JK (2007–2018). The selected black calipers use 6 service pistons each; matching the factory or specified conversion hardware is essential to the complete installation. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc-brake systems for motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must match the complete braking 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.
