Wilwood Front AERO6-DM Conversion, Red Calipers & Drilled Rotors, Toyota 4Runner / Lexus GX460 (2015–2024)

Red AERO6-DM calipers provide the hydraulic service braking in this Wilwood front conversion for Toyota 4Runner / Lexus GX460 (2015–2024). They work with 13.31 × 1.26-inch srp drilled & slotted rotors; the vehicle designation must be considered together with the mounting details below. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. Its work covers the design and manufacture of disc-brake systems and components for specialized vehicles, motorsport and street-performance use. The product range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines; compatibility depends on the complete system.

Technical Details

Fitment & Compatibility

Toyota 4Runner applications extend through 2024 and Lexus GX460 through 2023 in the table below; check the individual trim/year row. DS1551 requires clearancing the dust shield for caliper mounting. These are the later factory front-upright applications and their specified piston area, not every six-lug Toyota/Lexus hub. Compare the rotor register and 17-inch wheel template before installation.

With more than 20 years of parts experience, PMB Performance can help compare your VIN and installed hardware with the required configuration. Include any suspension, wheel or axle changes.

Review Installation instructions for the complete installation and clearance requirements.
