2017–2020 Dodge Durango with Vented Rear Rotor

DBA42633

Overview:

The DBA 4000 Series Plain Rotor (REAR) is a high-performance direct replacement brake rotor designed specifically for the 2017 to 2020 Dodge Durango models equipped with vented rear rotors. Engineered for drivers seeking enhanced braking performance beyond standard OEM levels, this rotor delivers reliable stopping power and improved heat management under demanding conditions. Ideal for daily driving, towing, or spirited driving, the 4000 Series rotor offers a balance of durability, cooling efficiency, and consistent braking feel.

Crafted to meet the needs of enthusiasts and everyday drivers alike, this rotor provides a smooth, OE-style finish while incorporating advanced technology to reduce brake fade and extend the life of both pads and rotors. It is a perfect upgrade for those wanting dependable performance without compromising factory aesthetics.

Key Features:

The DBA 4000 Series Plain Rotor incorporates innovative design and materials to optimize braking performance and longevity. Key features include:

• Kangaroo Paw Ventilation System: Features 144 diamond and teardrop-shaped pillars that increase surface area by up to 30%, improving cooling efficiency by 20% compared to traditional straight vane rotors.
• XG-150 High Carbon Alloyed Iron: This specially formulated high carbon iron alloy enhances thermal capacity, reducing the risk of warping and cracking under extreme heat.
• Thermal Stability Profiling (TSP): A proprietary heat treatment process that improves rotor durability and resistance to thermal fatigue.
• Thermographic Temperature Monitoring: Heat-sensitive paint markings change color at specific temperature thresholds, allowing drivers to monitor brake temperatures and rotor condition.
• Paint Protection on Non-Friction Areas: Prevents corrosion and rust formation, maintaining a clean, attractive appearance over time.
• OE Style Smooth Finish: Provides a factory-like look suitable for controlled race divisions or street use.

Construction & Design:

The rotor is cast from DBA’s proprietary XG-150 high carbon alloyed iron, which is engineered to withstand the intense heat and stress generated during heavy braking. This material, combined with the Thermal Stability Profiling process, ensures the rotor maintains structural integrity and resists warping or cracking over extended use.

The patented Kangaroo Paw ventilation design enhances airflow through the rotor, significantly improving heat dissipation. This innovative venting system reduces brake fade and mechanical damage, resulting in longer service life for both the rotor and brake pads. Additionally, the rotor’s smooth, OE-style finish offers a clean appearance while maintaining high performance.

Installation & Fitment:

This rotor is a direct bolt-on replacement for the rear vented rotors on Dodge Durango models from 2017 to 2020. No modifications are required for installation, making it a straightforward upgrade for those maintaining or enhancing their vehicle’s braking system. It is recommended to verify your existing rotor and pad measurements to ensure compatibility, especially if your vehicle has a non-standard brake package.

What's Included:

• One DBA 4000 Series Plain Rear Brake Rotor (vented)
• Protective coating on non-friction surfaces
• Heat-sensitive thermographic paint markings

Ideal For:

This rotor is ideal for Dodge Durango owners who demand improved braking performance and durability over stock rotors without sacrificing the original factory appearance. It suits daily drivers, towing enthusiasts, and those who occasionally push their vehicle harder on the road or track. The rotor’s advanced cooling and material technology make it well-suited for vehicles subjected to frequent heavy braking or elevated temperatures.
