Upgrade the rear braking system of your heavy-duty truck with the Timbren TIM-R225328 BES Severe-Duty Brake Rotor. Designed for demanding towing, hauling, and work applications, this direct-fit replacement helps address the heat, vibration, and corrosion issues that can affect standard brake rotors. It fits select 2020 Chevrolet Silverado 3500 HD and 2020–2021 GMC Sierra 3500 HD applications, providing reliable performance for vehicles operating under heavy loads.
The rotor features Timbren OnyxBond™ hybrid corrosion protection, a matte black coating engineered to resist road salt, moisture, and extreme temperatures. Rated for temperatures up to 932 degrees Fahrenheit, OnyxBond™ offers a higher heat threshold than typical zinc coatings, helping maintain consistent braking performance during repeated high-temperature stops. The OEM-style vane design promotes efficient heat dissipation, supporting improved thermal recovery and reducing the risk of brake fade under load.
Each Timbren BES rotor is manufactured from premium-grade iron and precision machined to OE specifications for dependable fitment and smooth operation. Fly-cut balancing helps minimize pedal pulsation, steering-wheel vibration, and braking shudder, while the non-directional finish promotes even brake pad bed-in. The rear-position design and direct-fit construction support a straightforward installation using compatible factory components, making this rotor a practical reliability upgrade for towing and commercial-duty applications.
Choose the Timbren TIM-R225328 when you need durable rear braking performance for a heavy-duty Chevrolet Silverado 3500 HD or GMC Sierra 3500 HD. Professional installation is recommended, and brake system components should be inspected before installation to ensure proper operation.
