Product details
The anodized front right Wilwood AeroDM for Toyota 4Runner is an individual brake caliper. It combines a 5.04-inch attachment span with 1.75/1.50/1.50-inch piston bores; confirm the rotor centerline and 1.25-inch width configuration before installation. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another. 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.
