DFC Slotted Hi-Carbon Alloy Rotor

2005–2023 Chrysler 300 Rear

Part #: 910-39020

Overview

The DFC Slotted Hi-Carbon Alloy Rotor is a premium rear brake rotor designed specifically for Chrysler 300 models from 2005 through 2023. Engineered to deliver enhanced braking performance, this rotor is ideal for drivers seeking improved stopping power, durability, and heat management. Whether you are replacing worn-out rotors or upgrading your braking system, the DFC rotor offers reliable, consistent braking under daily driving or more spirited conditions.

Built with high-quality materials and advanced manufacturing techniques, this rotor ensures smooth, vibration-free stops while maintaining long-term resistance to wear and corrosion. Its slotted design aids in debris removal and heat dissipation, helping to reduce brake fade and maintain optimal braking efficiency.

Key Features

Designed with precision and performance in mind, the DFC Slotted Hi-Carbon Alloy Rotor includes the following key features:

• Constructed from premium G3000 and G11H18 iron castings for superior strength, stability, and durability
• Original Equipment (OE) vane configuration ensures proper airflow and maximum heat dissipation
• 100% precision mill-balanced to provide smoother stops and eliminate vibration at any speed
• Fined turned finish with 16 RMS surface smoothness improves initial rotor and pad break-in
• Geomet® coating offers high-performance corrosion protection against rust and environmental damage
• Disc thickness variation (DTV) limited to 0.010 mm maximum for consistent braking surface
• Lateral runout controlled to 0.050 mm maximum for reliable, vibration-free operation
• Slotted rotor design enhances heat dissipation and helps remove brake dust and gases

Construction & Design

The rotor is expertly crafted using a blend of G3000 and G11H18 high-carbon iron castings, materials known for their excellent thermal conductivity and mechanical strength. This combination provides enhanced resistance to warping and cracking under high heat conditions, ensuring long-lasting durability. The original equipment vane design promotes efficient airflow, which is critical for maintaining lower operating temperatures and preventing brake fade during heavy use.

Each rotor undergoes precision mill balancing to eliminate vibrations and ensure smooth braking performance. The finely turned surface finish with a 16 RMS rating facilitates optimal pad bedding, reducing noise and improving initial braking response. Additionally, the Geomet® coating protects the rotor surface from corrosion, extending the rotor’s service life even in harsh weather conditions.

Performance & Sound

The slotted design of this rotor not only improves heat dissipation but also helps evacuate brake dust and gases generated during braking. This results in more consistent brake pad contact and reduced brake fade, especially during aggressive driving or towing. The precision balancing and smooth finish contribute to quieter operation and eliminate the vibrations commonly associated with lower-quality rotors.

Installation & Fitment

The DFC Slotted Hi-Carbon Alloy Rotor is designed as a direct replacement for the rear rotors on Chrysler 300 models from 2005 to 2023. It fits precisely without the need for modifications, making installation straightforward for professional mechanics and experienced DIY enthusiasts alike. Proper installation ensures optimal rotor performance and longevity.

What’s Included

• One rear slotted hi-carbon alloy rotor (driver or passenger side)
• Protective Geomet® corrosion-resistant coating
• Installation instructions (where applicable)

Ideal For

This rotor is ideal for Chrysler 300 owners who demand reliable, high-performance braking with enhanced durability. It suits daily drivers looking to maintain factory-level braking quality as well as enthusiasts who require improved heat management and fade resistance for spirited driving or towing applications. The rotor’s corrosion protection also makes it a great choice for vehicles exposed to wet or salty environments.
