Product details
Black powder coating covers the left-hand AeroDM six-piston caliper for Wilwood’s 2024–2025 Toyota Tacoma front package. The caliper uses a 7.08-inch direct lug interface and a staggered 1.62/1.38/1.38-inch bore layout. The surrounding conversion is an essential part of the application, not an optional assumption based on the vehicle name. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among its products, selected according to the complete brake system’s requirements.
