GMC Sierra 3500 HD Brake Rotor (1) - Rear - Timbren - BES Severe-Duty OnyxBond - Matte Black - 2020–2026. A direct-fit rear rotor built for heavy towing, hauling, and dependable daily use.

Timbren BES Severe-Duty rotors address the core cause of braking issues: heat. The OnyxBond™ matte black coating provides a durable barrier against corrosion and extreme temperatures, rated to 932°F with a 67% higher heat tolerance than typical zinc-coated rotors. Each unit is fly-cut balanced to reduce pedal pulsation and steering vibration. An OEM-style vane design aids heat dissipation under load, while a non-directional finish supports even pad bed-in. Built from premium iron and precision machined to OE specs, this single rear rotor installs as a true replacement and is ready for demanding duty cycles.
