Fitment Notes

• Rear left (driver side) rotor only - sold individually; order AR82155XR for the right/passenger side or AR82155XPR for the complete rear pair
• Designed for Single Rear Wheel (SRW) configurations; confirm fitment on Dual Rear Wheel (DRW) applications before ordering
• 8-lug bolt pattern; compatible with all gas and diesel engine variants across all listed model years
• For the matching front rotors on the same vehicles, see PowerStop AR82153XPR

Features

• Cross-drilled holes maximize heat dissipation under heavy towing, hauling, and repeated hard braking conditions
• Rounded slots sweep gas, moisture, and debris off the pad surface every revolution for clean, consistent friction contact
• Silver Zinc Dichromate plating on all exterior surfaces guards against rust and corrosion for long-lasting appearance
• G3000 grade cast iron construction provides the thermal mass and structural strength required for HD truck applications
• 100% mill-balanced for smooth, vibration-free pedal feel and quiet braking from the first stop
• Chamfered drill holes and rounded slot edges minimize stress concentration to reduce the risk of cracking over time
• Manufactured to OE vane count and rotor weight for correct rear brake bias and heat management
• Direct bolt-on fitment to factory rear caliper brackets - no modifications, spacers, or adapters required

Product Description

The PowerStop AR82155XL is a rear left Evolution drilled and slotted brake rotor engineered for the 2011-2024 Chevrolet Silverado 2500 HD and 3500 HD, the 2016-2019 Suburban 3500 HD, and the 2011-2024 GMC Sierra 2500 HD and 3500 HD. Machined from G3000 grade cast iron to OE vane count and weight specs, it bolts directly onto the factory rear caliper bracket without any modification. Silver Zinc Dichromate plating protects all non-friction surfaces from rust and corrosion for a sharp look that holds up on the road and the worksite.

The cross-drilled and slotted design delivers meaningful performance gains for HD trucks that regularly tow and haul - drilled holes vent heat faster than smooth OE rotors under sustained load, while rounded slots keep the friction surface clean for reliable stopping power in any condition. The rotor is 100% mill-balanced to eliminate rear brake vibration and pedal pulsation. Order with AR82155XR for a complete rear axle set, or pair with AR82153XPR front rotors for a full axle-to-axle upgrade.
