The Timbren TIM-R205258 BES Severe-Duty Rear Brake Rotor is engineered for demanding towing, hauling, and heavy-duty driving applications. Designed to address heat-related brake performance issues, this rear rotor uses OnyxBond™ technology, a matte black hybrid coating that helps protect against corrosion while withstanding temperatures up to 932 degrees Fahrenheit. This enhanced thermal resistance helps reduce the risk of warping, pedal pulsation, and brake fade during repeated or high-load stops.
Constructed from premium-grade iron, the Timbren BES rotor is precision machined to OE specifications for a direct-fit replacement. Its OEM-style vane design supports efficient heat dissipation, helping maintain consistent braking performance when your Ford F-150 is working under load. Each rotor is fly-cut balanced to minimize vibration through the brake pedal and steering wheel, while the non-directional finish promotes even brake pad bed-in for smooth, predictable operation.
The OnyxBond™ coating also provides durable protection against road salt, moisture, and other environmental contaminants that can contribute to rust and premature wear. By helping keep the rotor and cooling vanes protected, this finish supports long service life and reliable thermal recovery. Intended for the rear axle, the Timbren TIM-R205258 provides a professional-grade braking upgrade for select 2015–2016 Ford F-150 applications. Verify vehicle configuration and brake fitment before installation.
