DFC Hi-Carbon Alloy Geomet Rotor

2019–2023 Chrysler 300 Rear

Part #: 900-39020

Overview

The DFC Hi-Carbon Alloy Geomet Rotor is a premium rear brake rotor designed specifically for the 2019–2023 Chrysler 300. Engineered to deliver reliable stopping power and long-lasting durability, this rotor is ideal for drivers seeking a high-quality replacement that meets or exceeds original equipment (OE) standards. Its advanced construction ensures consistent brake performance under a variety of driving conditions, from daily commuting to spirited driving.

Built with precision and coated for corrosion resistance, the DFC rotor helps maintain optimal braking efficiency while protecting against rust and wear. This rotor is an excellent choice for Chrysler 300 owners who demand dependable braking performance combined with enhanced longevity and smooth operation.

Key Features

Designed with both performance and durability in mind, the DFC Hi-Carbon Alloy Geomet Rotor offers the following key features:

• Premium G3000/G11H18 iron castings provide superior strength, stability, and durability
• Original Equipment (OE) vane configuration maximizes heat dissipation to reduce brake fade
• 100% precision mill-balanced for vibration-free, smooth stopping at any speed
• Fined turned finish (16 RMS) promotes improved 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 ensures rotor flatness and consistent braking
• Lateral runout capped at 0.050 mm for optimal rotor alignment and performance

Construction & Design

The rotor is crafted from premium G3000/G11H18 iron castings, known for their excellent mechanical properties that enhance strength and thermal stability. This high-carbon alloy composition improves wear resistance and reduces the risk of cracking under heavy braking loads. The original equipment vane design optimizes airflow through the rotor, effectively dissipating heat to maintain cooler operating temperatures and prevent brake fade during demanding use.

Additionally, the finely turned finish with a 16 RMS surface roughness ensures a smooth mating surface for brake pads, facilitating quicker and more effective break-in. The Geomet® coating applied to the rotor surface provides a durable barrier against corrosion, extending the rotor’s service life and maintaining its appearance even in harsh weather conditions.

Installation & Fitment

This rear rotor is designed as a direct fit replacement for the 2019 through 2023 Chrysler 300 models, requiring no modifications for installation. It is engineered to meet or exceed OEM specifications, ensuring compatibility with the vehicle’s original braking system components. Installation can be performed using standard brake service procedures, making it suitable for professional mechanics and experienced DIY enthusiasts alike.
