Product Details

The Power Stop rear drilled, slotted and zinc plated brake rotor pair is engineered for consistent braking performance in everyday driving and demanding conditions. Precision cross-drilling and rounded slots work together to maintain a cleaner pad-to-rotor contact patch, while the vented construction helps move heat away from the braking surface. AR82137XPR is a practical choice for rear brake service on the Chevrolet Caprice, Chevrolet SS, and Pontiac G8 when OE-style fitment and a corrosion-resistant finish are priorities.

This part cross-references Raybestos Brakes 580724 for the same application.

Common Brake Issues It Can Address

• Rear rotor wear that requires replacement
• Surface rust and corrosion on exposed brake components
• Brake dust buildup affecting rotor contact consistency
• Heat-related brake fade during repeated stops
• Uneven braking feel caused by worn or damaged rear rotors

Installation Notes and Tips

Verify rotor dimensions before installation, including the 324 mm outside diameter, 20 mm nominal thickness, 20 mm discard thickness, and 55.5 mm overall height. Confirm rear position fitment and 5-lug, 120 mm bolt circle specifications before service.
