The directional surface pattern helps channel gases and debris away from the contact area, reducing brake fade during demanding driving conditions. The rotor features a nominal thickness of 29 mm and a discard thickness of 27 mm, ensuring a long service life before replacement is necessary. Its zinc silver coated hat finish provides corrosion resistance, maintaining structural integrity and appearance over time. With eight bolt holes sized at 16.5 mm and a bolt circle diameter of 165.1 mm, this rotor fits securely on compatible Chevrolet and GMC models.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis rotor is compatible with a range of Chevrolet and GMC heavy-duty trucks and vans, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eChevrolet Silverado 2500, 2500 HD, 2500 HD Classic, 3500, and 3500 HD\u003c\/li\u003e\n\u003cli\u003eGMC Sierra 2500, 2500 HD, 2500 HD Classic, 3500, 3500 Classic, and 3500 HD\u003c\/li\u003e\n\u003cli\u003eChevrolet Avalanche 2500 and Suburban 2500\u003c\/li\u003e\n\u003cli\u003eGMC Yukon XL 2500\u003c\/li\u003e\n\u003cli\u003eChevrolet Express 2500, 3500 and GMC Savana 2500, 3500\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade caused by excessive heat buildup during heavy towing or hauling\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear due to poor rotor surface design\u003c\/li\u003e\n\u003cli\u003eCorrosion and rust on rotor hats reducing lifespan\u003c\/li\u003e\n\u003cli\u003eReduced braking performance from warped or worn rotors\u003c\/li\u003e\n\u003cli\u003eBrake noise and vibration from glazed or damaged rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 27 mm to maintain safety standards. Use proper torque specifications for the eight 16.5 mm bolt holes to secure the rotor firmly. The directional drilled and slotted surface must be installed following the correct rotation direction for optimal performance. It is recommended to inspect brake pads and replace if worn when installing new rotors.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM specifications for Chevrolet and GMC heavy-duty vehicles.
