Timbren BES Severe Duty Semi-Metallic Brake Pads OnyxBite (REAR)

2019–2026 Ram 2500/3500 6.4L 392 / 6.7L Diesel

Part #: TIM-D2225SD

Overview

The Timbren BES Severe Duty Semi-Metallic Brake Pads OnyxBite are engineered specifically for heavy-duty applications on Ram 2500 and 3500 trucks equipped with 6.4L 392 HEMI or 6.7L diesel engines from 2019 through 2026. Designed for the 1% of truck owners who push their vehicles to the limit, these brake pads provide a severe-duty upgrade that excels under maximum Gross Vehicle Weight Rating (GVWR) conditions.

Unlike conventional ceramic pads that focus on low dust and quiet operation, the OnyxBite™ compound prioritizes stopping power and pedal responsiveness. This makes them ideal for drivers who tow trailers, boats, or haul heavy loads, delivering a firm, confident brake feel and significantly reduced stopping distances. These pads are built to withstand the intense heat and stress of demanding work environments without fading or glazing.

Key Features

The Timbren BES OnyxBite brake pads combine advanced materials and design to meet the rigorous demands of severe-duty braking. Key features include:

• High-friction, low-metallic semi-metallic compound for superior stopping power
• Thermally stable formulation resists glazing and brake fade under heavy use
• Multi-layer rubber shims and precision chamfers reduce harmonic vibration and eliminate squeal
• Fully compliant with 2025 copper-free environmental standards
• Designed specifically for rear brake applications on Ram 2500/3500 6.4L 392 and 6.7L Diesel models
• Durable construction optimized for towing and hauling heavy loads
• Includes a complete stainless steel hardware kit for professional, noise-free installation
• Backed by Timbren’s 42-month or 42,000-mile warranty for long-term reliability

Construction & Design

The OnyxBite brake pads utilize a semi-metallic compound that balances high friction with thermal durability. This compound is engineered to maintain consistent performance even when exposed to the extreme heat generated during heavy braking. The pads feature multi-layer rubber shims that act as vibration dampers, reducing brake noise and harshness commonly associated with heavy-duty friction materials.

Precision chamfering on the pad edges further minimizes noise and ensures smooth engagement with the rotor. The stainless steel hardware kit included with each set enhances installation quality and helps maintain pad alignment and retention, contributing to consistent braking performance over time.

Performance & Sound

OnyxBite brake pads deliver a firm and responsive pedal feel, providing drivers with confidence when hauling or towing heavy loads. The high-friction compound ensures a strong initial bite, which is critical for reducing stopping distances in demanding conditions. The advanced shim and chamfer design effectively suppresses brake squeal and vibration, resulting in a quieter, more comfortable driving experience without sacrificing performance.

Installation & Fitment

These brake pads are designed as a direct fit replacement for the rear brakes on 2019–2026 Ram 2500 and 3500 models equipped with 6.4L 392 HEMI or 6.7L Diesel engines. Installation requires no modifications and can be completed using standard brake service procedures. The included stainless steel hardware kit ensures a secure, professional installation that maintains proper pad positioning and reduces noise.
