DFC High-Carbon GEOMET Rotor

2021–2023 Dodge Challenger & 2021–2022 Dodge Charger 5.7L / 6.1L / 6.2L / 6.4L Engines

Part #: 900-40128D

Overview

The DFC High-Carbon GEOMET Rotor is a premium replacement brake rotor engineered 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. Designed for enthusiasts and drivers who demand reliable, consistent braking performance, this rotor delivers enhanced strength, heat management, and corrosion resistance to meet the rigorous demands of spirited driving and daily use.

Built to OEM vane specifications, this rotor ensures optimal airflow and heat dissipation, reducing the risk of brake fade during aggressive driving or extended braking sessions. Its high-carbon alloy construction and precision balancing provide smooth, vibration-free stopping power, making it an ideal upgrade or replacement for worn factory rotors.

Key Features

Engineered for durability and performance, the DFC High-Carbon GEOMET Rotor offers the following key benefits:

• Constructed from premium G3000/G11H18 high-carbon iron castings for superior strength and stability
• Original equipment (OE) vane configuration maximizes heat dissipation to prevent overheating
• 100% precision mill-balanced to eliminate vibrations and ensure smooth braking at all speeds
• Fined turned finish (16 RMS) enhances initial rotor and pad break-in for improved pad seating and reduced noise
• GEOMET® coating provides advanced corrosion protection, extending rotor life and maintaining appearance
• Strict manufacturing tolerances with a maximum disc thickness variation (DTV) of 0.010 mm
• Maximum lateral runout limited to 0.050 mm for consistent braking performance and even pad wear

Construction & Design

This rotor is precision-engineered using a high-carbon alloy iron blend (G3000/G11H18), which enhances thermal conductivity and structural integrity compared to standard cast iron rotors. The high-carbon content improves wear resistance and reduces the risk of cracking under extreme thermal stress. The rotor’s original equipment vane design optimizes airflow through the rotor, effectively dissipating heat generated during braking to maintain consistent stopping power and reduce brake fade.

The finely turned surface finish promotes a smooth mating surface for brake pads, accelerating the break-in process and minimizing noise and vibration. The GEOMET® coating is a high-performance, environmentally friendly finish that protects the rotor from rust and corrosion without interfering with braking performance, ensuring long-lasting durability even in harsh weather conditions.

Installation & Fitment

The DFC High-Carbon GEOMET Rotor is a direct fit replacement for the left front position on the following vehicles: 2021–2023 Dodge Challenger R/T Scat Pack, SRT Hellcat, SRT Hellcat Redeye, SRT Jailbreak, and 2021–2023 Dodge Charger Scat Pack models equipped with 5.7L, 6.1L, 6.2L, and 6.4L engines. Installation requires no modifications and can be completed using standard brake service procedures. This rotor is designed to work seamlessly with factory brake pads and calipers, providing a hassle-free upgrade or replacement solution.
