Timbren BES Coated Brake Rotor OnyxBond

2009–2026 Dodge Ram 2500 / 3500 / 4000 5.7L Hemi, 6.4L 392 & 6.7L Diesel

Part #: TIM-R145192

Overview

The Timbren BES Coated Brake Rotor with OnyxBond™ technology is engineered specifically for heavy-duty Ram trucks, including the 2500, 3500, and 4000 series from 2009 through 2026. Designed to withstand the extreme demands of towing and hauling, these rear rotors address the most common failure point in heavy-duty braking systems: heat-induced wear and warping. Featuring a proprietary matte black OnyxBond™ coating, these rotors provide superior resistance to corrosion and thermal stress, ensuring consistent braking performance under the toughest conditions.

Ideal for drivers who regularly tow heavy equipment, campers, or operate in harsh environments, Timbren BES rotors deliver enhanced durability and reliability. They maintain structural integrity and thermal recovery, reducing brake fade and pedal pulsation for safer, more confident stops.

Key Features

These rotors incorporate advanced materials and manufacturing techniques to meet the rigorous demands of severe-duty applications. Key features include:

• OnyxBond™ Coating: Proprietary matte black finish rated for temperatures up to 932°F, providing a 67% higher heat threshold than standard zinc coatings.
• Severe-Duty Heat Management: Engineered to resist thermal stress that causes warping and brake fade during heavy towing and hauling.
• Fly-Cut Balanced: Precision balancing eliminates vibrations and brake shudder for smooth, stable braking performance.
• Corrosion Resistance: Robust barrier against road salt, moisture, and debris to keep cooling vanes rust-free and effective.
• Direct Fit Replacement: Designed for straightforward installation with factory specifications, ensuring compatibility and reliability.
• Heavy-Duty Construction: Built to withstand the rigors of professional-grade use and extended highway hauls.

Construction & Design

The Timbren BES rotors are crafted from high-quality cast iron optimized for thermal conductivity and durability. The OnyxBond™ coating is applied through a proprietary process that bonds a matte black finish to the rotor surface, creating a tough shield against corrosion and extreme heat. This coating not only extends rotor life but also maintains the integrity of the cooling vanes, which are critical for dissipating heat during braking.

Each rotor undergoes a fly-cut balancing process to ensure uniform weight distribution, reducing the risk of vibrations and brake pedal pulsation. This precision manufacturing results in a rotor that performs reliably under the high torque and stress typical of heavy-duty Ram trucks.

Installation & Fitment

These rotors are designed as direct-fit replacements for the rear brakes on 2009–2010 Dodge Ram 2500 and 3500 models with 5.7L Hemi and 6.7L Diesel engines, as well as 2011–2026 Ram 2500 and 3500 models including the 6.4L 392 variant. Installation requires no modifications, allowing for a straightforward swap with factory components. This ensures a hassle-free upgrade that immediately enhances braking reliability and performance.

What's Included
