Detailed Product Overview

PowerStop AR83100XPR is designed around the needs of heavy-duty rear braking. The cross-drilled pattern helps move heat away from the rotor face, while the rounded slots clear gas, dust, and moisture from the friction area to maintain consistent pad contact. With an outside diameter of 365.00 mm, overall height of 134.10 mm, nominal thickness of 38.00 mm, and discard thickness of 36.40 mm, this rotor set is built to match the listed OE dimensions for the rear axle.

Compatible With 2019-2021 Ram 3500, rear dual rear wheel 365 mm rotor applications, and 2022-2023 Ram 3500, rear dual rear wheel applications. If you are searching for a rear brake rotor replacement for Ram 3500 dual rear wheel trucks, AR83100XPR provides a direct-fit solution with a corrosion-resistant finish and a vented, slotted X drilled surface.

This part cross-references 6829 0077AA and 6829 0077AB for the same application.

What It Helps Address

• Brake fade during repeated stops or heavy-duty use
