DFC High-Carbon GEOMET Rotor

2021–2023 Dodge Challenger & Charger 5.7L / 6.1L / 6.2L / 6.4L Engines

Part #: 900-40129D

Overview

The DFC High-Carbon GEOMET Rotor is a premium right front brake rotor designed specifically for Dodge Challenger and Charger models equipped with 5.7L Hemi, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 engines from 2021 through 2023. Crafted to meet the demands of both daily driving and spirited performance, this rotor delivers enhanced braking reliability, durability, and heat management. Whether you are replacing worn factory rotors or upgrading your braking system for improved stopping power and longevity, this rotor provides a direct-fit solution engineered to maintain optimal performance under aggressive conditions.

Built with high-carbon iron and advanced GEOMET coating, it offers superior corrosion resistance and structural integrity, ensuring consistent braking performance and extended service life. This rotor is ideal for enthusiasts who demand smooth, vibration-free stops and long-lasting durability from their braking components.

Key Features

Designed with precision and quality in mind, the DFC High-Carbon GEOMET Rotor incorporates several advanced features to enhance braking performance and reliability:

• Engineered from premium G3000/G11H18 high-carbon iron castings for exceptional strength and durability
• Original Equipment (OE) vane configuration optimized for maximum heat dissipation and thermal stability
• 100% precision mill-balanced to eliminate vibrations and ensure smooth, consistent stopping at all speeds
• Fined turned finish with a 16 RMS surface texture to improve initial rotor and pad break-in, enhancing braking response
• GEOMET coating provides high-performance corrosion protection, preventing rust and maintaining rotor appearance
• Strict quality control with maximum disc thickness variation of 0.010 mm and lateral runout limited to 0.050 mm for precise fitment and reliable operation

Construction & Design

The rotor is constructed using premium G3000/G11H18 iron castings, a high-carbon alloy known for its superior strength and wear resistance compared to standard cast iron. This material choice enhances the rotor’s ability to withstand the thermal and mechanical stresses generated during aggressive braking. The original equipment vane design promotes efficient airflow through the rotor, which helps dissipate heat quickly and reduces the risk of brake fade during extended use.

Additionally, the rotor’s fined turned finish ensures a smooth mating surface for brake pads, reducing noise and improving pad life. The GEOMET coating is a specialized, environmentally friendly protective layer that guards against corrosion without affecting braking performance, making it ideal for vehicles exposed to harsh weather or road conditions.

Installation & Fitment

This rotor is a direct replacement for the right front position on select Dodge Challenger and Charger models from 2021 to 2023. It fits the following engines and trims:

• 2021–2023 Dodge Challenger 5.7L Hemi
• 2021–2022 Dodge Challenger 6.1L SRT8
• 2022 Dodge Challenger 6.2L Hellcat
• 2021–2023 Dodge Challenger 6.4L 392
• 2021–2023 Dodge Charger 5.7L Hemi
• 2021–2023 Dodge Charger 6.4L 392

Installation requires no modifications and can be completed using standard brake service procedures. It is recommended to replace rotors in pairs for balanced braking performance and to inspect brake pads and hardware during installation.
