Ram 3500 Brake Rotor (1) – Rear – Timbren BES Severe-Duty with OnyxBond Coating – ’19–’26. This single rear rotor is built for heavy towing and hard-use braking where heat and durability matter.

Designed as a precision, direct-fit replacement, the BES Severe-Duty rotor manages the most common failure point in heavy-duty braking: heat. The OnyxBond coating is rated to 932°F and offers a 67% higher heat threshold than typical zinc-coated rotors, helping resist brake fade, warping, and pedal pulsation under load. Premium-grade iron and OE-spec machining deliver smooth, consistent performance, while fly-cut balancing reduces vibration. The non-directional finish promotes even pad bed-in, and the OEM-style vane design moves heat efficiently. OnyxBond also protects against road salt and moisture to help keep cooling vanes clear.
