Ram 4000 Brake Rotor (1) - Front - Timbren BES Severe-Duty with OnyxBond - Matte Black (2011–2026). Heavy-duty, direct-fit front rotor built for towing and work.

BES Severe-Duty targets the main brake failure—heat. OnyxBond forms a durable barrier against corrosion and extreme temps, staying stable up to 932°F (about 67% higher than typical zinc). Each rotor is fly-cut balanced for smooth, shudder-free stops and machined to OE specs for precise fit. The matte black coating also guards cooling vanes from rust and debris to preserve airflow and consistent braking. Part no. TIM-R145191.
