StopTech Slotted Front Brake Rotor

2009–2022 Ram 2500 / 3500 5.7L / 6.4L / 6.7L Diesel / Hemi / 392

Part #: 126.67080SR

Overview

The StopTech Slotted Front Brake Rotor is a high-performance, one-piece direct replacement rotor designed specifically for Ram 2500 and 3500 trucks from 2009 through 2022. Compatible with a variety of engines including the 5.7L Hemi, 6.4L 392, and 6.7L Diesel, this rotor offers a significant upgrade over factory discs. Ideal for truck owners seeking enhanced braking power and reliability without modifying their stock brake system or calipers, these rotors improve safety and driving confidence in both everyday and demanding conditions.

Featuring a distinctive slotted design, these rotors help dissipate heat and brake dust more effectively than standard rotors. This reduces pad glazing and maintains consistent brake bite, resulting in improved stopping power in wet and dry environments. The StopTech Slotted Rotor is engineered to deliver superior performance while maintaining quiet operation and long service life.

Key Features

StopTech’s Slotted Front Brake Rotor combines advanced engineering with durable materials to elevate your Ram’s braking system. Key features include:

• Precision-machined slots that enhance heat dissipation and brake dust removal
• Improved pad bite and reduced glazing for consistent braking performance
• Black e-coating for corrosion resistance and a sleek appearance behind wheels
• High carbon metallurgy (in most applications) for increased crack resistance and quieter operation
• Direct bolt-on replacement for factory brake systems and stock calipers—no modifications required
• Compatible with a wide range of Ram 2500 and 3500 models from 2009 to 2022
• Designed to withstand the rigors of heavy-duty use and towing

Construction & Design

Constructed from premium high carbon cast iron, the StopTech Slotted Rotor offers enhanced thermal stability and durability compared to standard rotors. The high carbon content reduces the risk of cracking under extreme heat and stress, which is common in heavy-duty truck applications. The rotor’s surface is precision-machined to exact OEM specifications, ensuring a perfect fit and smooth braking operation.

Each rotor is finished with a black e-coating that protects against rust and corrosion, extending the rotor’s lifespan and maintaining its aesthetic appeal. The unique slot pattern is engineered to optimize airflow and brake dust evacuation, helping to keep braking surfaces clean and effective during extended use.

Performance & Sound

The slotted design of these rotors improves braking responsiveness by preventing pad glazing and maintaining consistent friction levels. This results in enhanced stopping power in both wet and dry conditions, making them well-suited for trucks that tow heavy loads or operate in variable weather. Additionally, the high carbon metallurgy contributes to quieter braking by reducing vibrations and noise typically associated with heavy braking.

Installation & Fitment

StopTech Slotted Front Brake Rotors are designed as direct replacements for factory rotors on Ram 2500 and 3500 models listed below. Installation is straightforward and requires no modifications to existing brake calipers or hardware. These rotors fit stock brake systems perfectly, allowing for a hassle-free upgrade that restores or improves braking performance.
