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.

PMB Performance has over 20 years of parts experience. Share the VIN and any changes to the axle, upright or wheels before ordering if the brake configuration is uncertain.
