Product details
Wilwood supplies this front right AeroDM brake caliper for Toyota 4Runner with a red finish. Its 5.04-inch mounting span and 1.25-inch-wide rotor configuration are key checks when selecting a single caliper for an existing system. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking 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.
