Stoptech Slotted Front Brake Rotors

2006–2024 Chrysler 300 / Dodge Challenger / Charger / Magnum SRT8 6.1L & 6.4L

126.63063SL / 126.63063SR

Overview:

Upgrade your braking system with Stoptech Slotted Front Brake Rotors, engineered specifically for Chrysler 300C, Dodge Challenger, Charger, and Magnum SRT8 models equipped with 6.1L or 6.4L engines from 2006 through 2024. These rotors are designed to enhance braking performance by improving pad bite and heat dissipation, delivering more consistent stopping power under demanding conditions. Ideal for enthusiasts seeking both improved safety and a sporty appearance, these rotors provide a reliable upgrade over factory components.

Stoptech’s slotted rotors help to clear away brake dust and debris from the pad surface, reducing glazing and maintaining optimal friction. Their aggressive slot pattern also aids in cooling, which minimizes brake fade during spirited driving or track use.

Key Features:

Stoptech Slotted Front Brake Rotors combine advanced engineering and quality materials to deliver superior braking performance. Key features include:

• Precision-machined slotted surface for enhanced pad bite and debris removal
• Black e-coated finish on both sides of the hat, inside cooling vanes, and outer edge for corrosion resistance
• Power Alloy metallurgy with optimized molybdenum and carbon content for increased hardness and tensile strength
• Directional slot pattern with distinct left and right side rotors to maximize cooling efficiency
• Designed to reduce lateral runout and ensure smooth, vibration-free braking
• Compatible with Stoptech Big Brake Kits for a cohesive performance upgrade
• TÜV-certified for performance, durability, and fitment quality
• Engineered specifically for 6.1L and 6.4L HEMI SRT8 engines

Construction & Design:

These rotors are crafted using Stoptech’s proprietary Power Alloy metallurgy, which enhances the casting’s microstructure by increasing molybdenum and carbon content. This process results in rotors with superior hardness and tensile strength, improving durability and resistance to cracking under extreme heat. The rotors feature a black electrostatic coating (e-coating) applied to critical areas including the rotor hat and cooling vanes, providing exceptional corrosion resistance even after prolonged exposure to road salts and moisture.

The unique directional slot design ensures that the slots never intersect with cooling vanes, preserving structural integrity and maximizing airflow through the rotor. This design promotes efficient heat dissipation, reducing brake fade and extending pad life.

Installation & Fitment:

Stoptech Slotted Front Brake Rotors are direct bolt-on replacements for the front rotors on 2006–2024 Chrysler 300, Dodge Challenger, Charger, and Magnum SRT8 models with 6.1L or 6.4L engines. No modifications are necessary, making installation straightforward for professional mechanics or experienced enthusiasts. These rotors are precision balanced and machined to factory specifications to ensure proper fitment and optimal braking performance.

What's Included:

• One left front slotted brake rotor (Part #126.63063SL)
• One right front slotted brake rotor (Part #126.63063SR)

Ideal For:

These rotors are perfect for drivers who demand improved braking performance and reliability from their Chrysler 300C, Dodge Challenger, Charger, or Magnum SRT8. Whether you are upgrading your street car for enhanced safety or preparing your vehicle for occasional track use, Stoptech slotted rotors provide a balanced solution that enhances both function and appearance. They are especially suited for owners of 6.1L and 6.4L HEMI-powered models seeking a durable, high-quality brake upgrade.

Stoptech produces brake kits, pads, rotors, and hydraulic components. For performance driving, heat management and confident stopping is key—especially when speeds rise and repeated stops generate heat. Whether you’re improving street braking feel or preparing for track duty, Stoptech components help deliver consistent, confidence-building braking performance.
