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.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Rotor Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation caused by rotor wear or thickness loss\u003c\/li\u003e\n\u003cli\u003eCorrosion on the hat, edge, or internal vanes\u003c\/li\u003e\n\u003cli\u003eUneven braking feel from a worn rear rotor surface\u003c\/li\u003e\n\u003cli\u003eVisible rust behind alloy wheels\u003c\/li\u003e\n\u003cli\u003eFitment problems from using a rotor that does not match OE specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm 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.
