Get smooth, quiet rear braking with the Raybestos Specialty Truck Disc Brake Rotor 581032, a rear disc brake rotor engineered for noise-prone truck, medium-duty, and air-disc applications. It drops in as a direct-fit replacement matched to OE fit, form, and function on the listed full-size trucks and SUVs, including the 2007-2020 Cadillac Escalade and Escalade ESV, 2007-2013 Escalade EXT, 2007-2013 Chevrolet Avalanche, 2007-2018 Chevrolet Silverado 1500, 2007-2020 Chevrolet Tahoe, 2007-2020 GMC Yukon, and more (all engines) — see the Buyer's Guide tab for the complete list.
- Vehicle-specific cooling vanes: the vented casting's cooling vane configuration is matched to the OE design for optimal cooling, reduced fade, less noise, and increased pad life.
- Application-specific cast iron: follows SAE standards for tensile strength, hardness, and iron grade for structural integrity and long service life.
- Corrosion protection: fully coated for rust protection — Grey Fusion 4.0® rated at 300-hour salt spray, or a Black Fusion painted hat and edge.
- Turned finish: the smooth, non-directional braking surface gives the pads an effective surface to engage right out of the box.
This drum-in-hat rear rotor measures 345 mm (13.583 in) outside diameter, 20 mm (0.787 in) nominal thickness, and 18.5 mm (0.728 in) discard thickness, with 6 mounting bolt holes on a 139.7 mm (5.5 in) bolt circle and 6 stud/lug holes; no ABS tone ring is included. Signs a rotor may need replacing include pulsation through the pedal, grooving or scoring, and thickness worn below the discard specification. The listed applications use two rotors, one per side — sold individually, so order two and replace both sides together as a matched set for even, balanced braking. Manufacturer part number 581032. Country of origin: China.
