Product Details

Power Stop’s drilled and slotted rotor line focuses on practical brake performance improvements without requiring special modifications. The AR82155XPR rotor pair uses a slotted X drilled surface to maintain a cleaner pad-to-rotor contact area, while the zinc-plated finish adds protection against surface corrosion. This makes it a strong fit for drivers looking for a rear brake rotor upgrade on Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD models.

This part cross-references Raybestos Brakes 580876 for the same application.
