Wilwood Red AERO6 Front Brake System, 14-Inch GT Slotted Rotors and Flexlines for Listed Jeep Wrangler JL/Gladiator Applications (Listed 2018–2025 Applications)

Choose the red-caliper GT rotor configuration of Wilwood's AERO6 front Jeep package when the vehicle matches a listed JL/JT application. The 14.00 × 1.25-inch slotted rotors use separate hats, and BP-20 pads work with six-piston radial service calipers. Supplied 33-inch braided flexlines still require routing checks at steering lock and suspension travel. Nominal 18-inch wheel diameter is only the starting point for clearance. From Camarillo, California, Wilwood Engineering develops disc-brake systems for street-performance, motorsport and specialized uses. Bill Wood founded the company in 1977. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form part of its range, and must be combined to match the demands of the complete brake system.

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.

Use PMB Performance’s 20+ years of parts and fitment experience when checking a modified brake layout. The installed mounting hardware and measured wheel space are more useful than model and year alone.
