Product details
The rotor and bracket determine whether this black Wilwood AeroDM front right brake caliper for Toyota 4Runner is the correct choice. Its 1.25-inch rotor-width configuration works with the lug mount and 6-piston layout detailed below. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures disc brake systems and their individual components. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood supplies a range encompassing calipers, rotors, master cylinders, valves, fittings and brake lines, all selected to match the complete system. AeroDM is a forged six-piston caliper using a vehicle-specific direct lug mount. It is intended for the matching Wilwood rotor and conversion geometry, rather than the stock rotor by itself. Verify the package, side and lug offset before ordering a replacement.

Fitment & Compatibility
Replacement caliper for the Wilwood AeroDM front conversion on Toyota 4Runner (2015–2021). The matching kit uses a 13.31 × 1.26-inch Wilwood rotor. Match the exact 5.04-inch lug mount, rotor centering and side; the caliper is not a stock 4Runner brake conversion on its own.
