Overview
PowerStop AR8641SCR is a rear disc brake rotor built as a direct bolt-on replacement for original equipment. It is designed for vehicles that need OE-style fitment, corrosion protection, and consistent braking performance.
This rotor fits a range of Chevrolet and GMC applications, including Silverado 1500, Sierra 1500, and Tahoe rear brake setups. The coated hat and edge design helps preserve appearance behind alloy wheels while matching OE specifications.
Key Features
- Part number AR8641SCR for easy identification
- Partially coated rotor with silver epoxy on corrosion-prone areas
- Vented full cast construction for OE-style braking support
- Mill balanced for smooth operation
- Smooth surface finish with rust-resistant coating
- Matches original equipment weight and vane count
Detailed Description
PowerStop AR8641SCR is a rear brake rotor engineered to match original equipment dimensions and performance targets. The vented, full cast design uses a 324 mm outside diameter, 20.00 mm nominal thickness, and 18.50 mm discard thickness, with a 139.70 mm bolt circle and six lug holes. The coated hat, outer edge, and vanes help resist corrosion in exposed areas, making it a practical choice for Chevrolet Silverado 1500, GMC Sierra 1500, and related rear brake applications. If you are replacing a worn rear rotor on a Chevrolet Silverado 1500 or GMC Sierra 1500, AR8641SCR provides the OE-style dimensions and coating needed for a clean, direct replacement.
Common Issues This Rotor Can Address
- Brake pulsation caused by rotor wear or thickness loss
- Corrosion on the hat, edge, or internal vanes
- Uneven braking feel from a worn rear rotor surface
- Visible rust behind alloy wheels
- Fitment problems from using a rotor that does not match OE specifications
Installation Notes and Tips
Confirm rear fitment against the vehicle notes before ordering, especially for 2007 Silverado 1500 Classic, 2007 Sierra 1500 Classic, and 2000-2002 Tahoe or Yukon applications with specific brake or axle configurations. This rotor is a direct bolt-on replacement, but the brake system should be inspected for pad wear, caliper condition, and hub surface corrosion during installation. Verify the part number AR8641SCR and compare the rotor dimensions to the removed part before assembly.
Quality Assurance
PowerStop designs this rotor to match OE performance and specifications, including weight and vane count, for guaranteed fitment. The coated surfaces add corrosion resistance where exposed metal is most vulnerable, supporting long-term appearance and service consistency.
