Wilwood Front AERO6 Brake Kit for Jeep Wrangler JL and Gladiator, Black Calipers with 14-Inch GT Rotors, Listed 2018–2025 Applications

Black AERO6 six-piston calipers and 14.00-inch GT slotted rotors provide the front conversion for the listed Jeep Wrangler JL and Gladiator applications. Separate aluminum hats and BP-20 pads are included, together with 33-inch flexlines. Wrangler and Gladiator year/trim coverage is not identical, so check the actual row for the vehicle rather than applying the overall 2018–2025 span to every model. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. It designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit is one configuration within that disc-brake-system range and must be matched to the vehicle build.

Fitment & Compatibility

The table covers Wrangler JL beginning with 2018 entries, later Wrangler applications through selected 2025 trims, and Gladiator entries beginning in 2020. Trim/year ranges differ, including 4xe and special-edition rows; read every applicable option in the table. This kit retains the documented existing hubs and is designed around the stated factory master-cylinder and ABS operation. Check the 18-inch wheel envelope and route the long flexlines for the actual suspension travel. Use the complete application table below for the individual year, submodel, brake configuration and note attached to each entry.

For fitment assistance, send PMB Performance the vehicle details together with the installed spindle or axle configuration and wheel measurements. We draw on 20+ years of parts and fitment experience to help assess the combination.
