Timbren Industries BES-14RB017 BES OnyxBond Coated Severe-Duty Brake Rotor

The Timbren BES-14RB017 is a severe-duty replacement brake rotor from Timbren's Brake Enhancement System (BES) lineup, engineered specifically for trucks and SUVs that tow and haul heavy loads. Built to outperform factory brake components under the most demanding conditions, this rotor is designed for drivers who regularly push their vehicles to the limits of their towing and hauling capacity.

OnyxBond™ Protective Coating Technology:

• Extreme heat resistance — Timbren's proprietary OnyxBond™ matte black coating is rated for temperatures up to 932°F (500°C), providing a 67% greater thermal threshold than standard factory brake coatings
• Corrosion defense — The OnyxBond™ layer acts as a robust barrier against road salt, moisture, mud, and debris, keeping cooling vanes clear and extending rotor service life
• Appearance and durability — The matte black finish maintains its integrity through storage periods between trips and under repeated thermal cycling

Precision Engineering:

• Cast from high-quality iron for superior structural integrity under heavy braking loads
• Double-disc ground machining process ensures a perfectly flat rotor surface, eliminating weight variations and preventing pedal pulsation
• Designed as a precision direct-fit replacement for factory equipment — no modifications required
• OE-spec dimensions for straightforward, DIY-friendly installation

Performance Benefits:

• Engineered to combat brake fade caused by thermal stress during extended towing or hauling
• Superior thermal recovery means consistent stopping power even after repeated heavy braking events
• Works optimally when paired with Timbren BES OnyxBite™ severe-duty brake pads for a fully matched pad-and-rotor system

The Timbren BES-14RB017 brake rotor is backed by Timbren's 42-month / 42,000-mile warranty — nearly double the coverage of typical OEM brake hardware — giving truck owners confidence whether navigating steep descents, job site traffic, or long highway hauls with a loaded trailer.
