Timbren BES Severe-Duty 8-Lug Rotor with OnyxBond Heat-Resistant Coating; Rear (11-26 Sierra 3500 HD SRW)

Most rotors feel fine when your truck is empty, but the second you hook up a trailer, the physics change. Heavy loads generate massive amounts of heat that can lead to dangerous brake fade. Precision-engineered specifically as a direct-fit upgrade, Timbren BES Rotors are built to master that exact stress.

• Advanced Heat Management: Features our proprietary OnyxBond™ matte black coating, which is heat-rated up to 932°F (500°C)—providing a 67% higher heat threshold than standard coatings to prevent premature thermal fade.
• Vibration-Free Stops: Each rotor is meticulously fly-cut balanced to eliminate the high-torque vibrations, shudder, and pedal pulsation common during heavy towing.
• Premium Double-Disc Ground Finish: Precision-machined on both sides simultaneously to guarantee perfectly flat surfaces and uniform thickness. This high-end process eliminates break-in variations and creates the ultimate mating surface designed specifically to pair with Timbren OnyxBite™ Severe-Duty Brake Pads.

• Robust Corrosion Resistance: The protective OnyxBond™ layer acts as a permanent barrier against rust, road salt, and moisture, keeping your cooling vanes clear of debris to ensure maximum longevity.
• Ready for Work: Designed as an exact, direct-fit replacement for your factory equipment, allowing for a straightforward, DIY-friendly installation.
• Confidence for 42,000 Miles. Every rotor is backed by our hassle-free 100-day money-back guarantee and a 42-month / 42,000-mile (67,000 km) warranty so you can run your truck hard with complete peace of mind.
