Fitment & Compatibility

DS1583 documents 2020-on Chevrolet Silverado and GMC Sierra 2500/3500 HD front brake hardware, with the eight-lug rotor and factory upright. The table below also names 1987 Chevrolet V10 Pickup and V10 Suburban; those applications need direct technical confirmation and are not established by the HD-truck installation instructions. Do not order for either V10 on model/year alone. Check hub registration, stud clearance and the full 20-inch wheel drawing.

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.
