Timbren BES Severe-Duty Rear Brake Rotor for Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD - OnyxBond Coating

Timbren BES Severe-Duty Rotors are engineered to solve the most common failure point in heavy-duty braking: heat. When hauling heavy equipment or campers, standard rotors often break down because of thermal stress, leading to warping, pedal pulsation, and dangerous brake fade. Timbren addresses this with OnyxBond™ technology, a proprietary matte black finish that provides a superior barrier against both corrosion and extreme temperatures. While typical zinc-coated rotors fail as temperatures rise, OnyxBond is rated for 932 degrees Fahrenheit, offering a 67% higher heat threshold to keep your braking performance consistent mile after mile. Beyond heat management, these rotors are manufactured for professional-grade smoothness. Each unit is fly-cut balanced to eliminate the vibrations and "shudder" that often occur during high-torque stops. The protective OnyxBond™ layer also serves as a robust defense against road salt and moisture, ensuring that the cooling vanes remain clear of rust and debris for maximum longevity. Designed as a precision, direct-fit replacement for your factory equipment, these rotors allow for a straightforward installation that immediately upgrades your truck's reliability. Whether you are navigating job site traffic or long highway hauls, the Timbren BES rotor provides the structural integrity and thermal recovery needed for the most demanding towing applications.

The Timbren 20-26 BES Severe-Duty Rear Brake Rotor for Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD is engineered to withstand the demanding conditions of heavy-duty towing and hauling. Featuring OnyxBond™ technology, this rotor offers an advanced matte black finish that provides exceptional resistance to corrosion and extreme heat. Rated to endure temperatures up to 932°F, it delivers 67% higher thermal capacity compared to standard zinc-coated rotors, ensuring consistent braking performance even during prolonged heavy loads. This increased heat tolerance significantly reduces the risk of warping, brake fade, and pedal pulsation, which are common issues in high-stress applications. Manufactured with precision, each rotor is fly-cut balanced to eliminate vibrations and shudder during high-torque stops, providing a smoother driving experience. The OnyxBond layer also acts as a robust barrier against road salt and moisture, helping to prevent rust and debris buildup that can compromise rotor longevity. Designed as a direct-fit replacement, installation is straightforward, allowing you to upgrade your truck’s braking system quickly and effectively. Whether navigating demanding job sites or extended highway trips, this rotor provides the structural integrity and thermal management needed for reliable braking performance. Built from premium-grade iron, these rotors are engineered to meet or exceed OEM specifications, ensuring a perfect fit and long-lasting durability. The non-directional finish promotes even pad bed-in, optimizing braking efficiency and pad life. Suitable for rear axle installation on compatible Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD models from 2020 and 2021, the Timbren BES rotor is an essential upgrade for heavy-duty towing and haul applications seeking enhanced safety and reliability.
