Wilwood Front Six-Piston GT Brake Package, Red, Ford Ranger (2019–2025), 13.38-Inch Rotors

For Ford Ranger (2019–2025), this front AERO6-DM kit uses red Wilwood calipers and gt 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.

Fitment & Compatibility

The current compatibility chart lists 2019–2025 Ford Ranger Lariat, XL and XLT, as shown below; DS1565 details the 2019–2022 installation. For later production, compare the installed factory upright, hub and hose route to that drawing before assembly. These six-piston calipers and one-piece 13.38-inch rotors require the full 17-inch wheel-envelope check. Use the fitment table below to check the complete application and option notes.
