Wilwood Front 13.31-Inch SRP Rotor & Black Caliper Kit, Toyota 4Runner / Lexus GX460 (2015–2024)

For Toyota 4Runner / Lexus GX460 (2015–2024), this front AERO6-DM kit uses black Wilwood calipers and srp drilled & slotted rotors. Its 6-piston hydraulic layout and 13.31-inch rotor diameter need to be checked against the actual hub, upright and wheel arrangement. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company makes disc-brake systems for street-performance, motorsport and specialized applications. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines are selected around the demands of the complete braking installation.

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.
