• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• Original Equipment (OE) vane configuration designed to maximize heat dissipation and reduce brake fade
• 100% precision mill-balanced to ensure smooth stopping performance and eliminate vibration at any speed
• Fined turned finish with a 16 RMS surface texture to improve initial rotor and pad break-in for longer pad life
• Geomet® coating provides high-performance corrosion resistance, protecting the rotor from rust and environmental damage
• Strict manufacturing tolerances with a maximum disc thickness variation of 0.010 mm for precise operation
• Maximum lateral runout limited to 0.050 mm to ensure optimal fit and smooth braking performance

Construction & Design

This rotor is crafted from premium G3000/G11H18 iron castings, known for their exceptional mechanical properties that enhance strength and thermal stability. The high-carbon alloy composition improves wear resistance and reduces the risk of cracking under extreme braking conditions. The original equipment vane design promotes efficient airflow through the rotor, helping to dissipate heat rapidly and maintain consistent braking performance.

The finely turned surface finish with a 16 RMS roughness ensures better pad bedding, which contributes to improved brake feel and extended pad life. Additionally, the Geomet® coating offers a durable, environmentally friendly protective layer that prevents corrosion without compromising braking efficiency.

Installation & Fitment

The DFC Hi-Carbon Alloy Geomet Coated Rotor is a direct fit replacement for the rear brakes of 2021 through 2025 Dodge Durango models. Designed to meet OEM specifications, it installs easily without the need for modifications or special tools. This rotor is compatible with the factory brake calipers and hardware, ensuring a hassle-free upgrade that restores or enhances your vehicle’s braking capability.
