Timbren Industries BES-56FB057 BES OnyxBond Coated Severe-Duty Brake Rotor

The Timbren Industries BES-56FB057 is a severe-duty brake rotor engineered as part of Timbren's BES (Brake Enhancement System) — a purpose-built brake upgrade for trucks and pickups that regularly tow and haul heavy loads. This rotor is a precision, direct-fit replacement for factory brake hardware, delivering significantly upgraded thermal performance and corrosion resistance over standard OEM rotors.

OnyxBond™ Proprietary Coating Technology:

• 932°F (500°C) heat rating — a 67% higher thermal threshold than standard factory brake coatings
• Proprietary matte black OnyxBond™ finish protects against rust, road salt, mud, and moisture
• Keeps cooling vanes clear of debris for sustained airflow and rotor longevity
• Maintains its protective finish during storage between towing seasons

Precision Manufacturing:

• Cast from high-quality iron for structural integrity under heavy braking loads
• Double-disc ground machining process ensures a perfectly flat rotor surface
• Fly-cut balanced to eliminate vibration, shudder, and pedal pulsation during high-torque stops
• OE-spec dimensions for straightforward, direct-fit installation

Performance Benefits:

• Resists warping and brake fade caused by thermal stress during extended towing or hauling
• Eliminates spongy pedal feel common under heavy load conditions
• Designed to pair with Timbren BES OnyxBite™ severe-duty brake pads for a fully matched system

Warranty: Backed by a 42-month / 42,000-mile warranty — nearly double the coverage of standard OEM brake hardware — plus a 100-day money-back guarantee.

The Timbren BES-56FB057 is built for truck owners who demand reliable, consistent stopping power when the stakes are highest. Whether navigating steep descents with a loaded trailer or managing job-site stop-and-go, this rotor delivers the thermal resilience and precision finish required for severe-duty braking applications.
