GMC Sierra 2500 Brake Rotor (1) - Front - Timbren BES Coated with OnyxBond™ - Matte Black - ’11–’26. A direct-fit heavy-duty rotor engineered for consistent braking under load.

Timbren’s BES Severe-Duty design tackles heat—the leading cause of warping and fade when towing or hauling. The proprietary OnyxBond™ matte black coating resists corrosion and is rated to 932°F, about 67% higher than typical zinc coatings. Precision OE-spec machining and fly-cut balancing curb pedal and steering vibration, while an OEM-style vane layout supports steady cooling. A non-directional surface promotes even pad bed-in on 2011–2026 Sierra 2500 HD applications.
