Overview:

The DBA 4000 Series Plain Rotor is a premium direct replacement rear brake rotor designed specifically for the Dodge Durango models from 2011 to 2020 equipped with vented rear discs. Engineered for drivers seeking enhanced braking performance beyond standard OEM levels, this rotor delivers reliable stopping power and durability under demanding conditions. Ideal for daily driving and spirited use, the 4000 Series rotor offers improved heat management and longevity without compromising the original equipment appearance.

Manufactured by DBA, a leader in high-performance braking solutions, this rotor is perfect for those who want a dependable upgrade that maintains OE fitment and function while providing superior thermal stability and resistance to brake fade.

Key Features:

The DBA 4000 Series Plain Rotor incorporates advanced technology and materials to ensure optimal braking performance and durability. Key features include:

• Kangaroo Paw Ventilation System: Features 144 diamond and teardrop-shaped pillars that increase surface area by up to 30%, enhancing cooling efficiency by 20% compared to traditional straight vane rotors.
• XG-150 High Carbon Alloyed Iron: This specialized metallurgy improves thermal capacity, reducing the risk of warping and cracking under extreme heat.
• Thermal Stability Profiling (TSP): A proprietary heat treatment process that strengthens the rotor to withstand repeated high-temperature braking without degradation.
• Thermographic Temperature Monitoring: Heat-sensitive paint markings change color at specific temperature thresholds, providing a visual indicator of rotor temperature and wear.
• Paint Protection on Non-Friction Areas: Enhances corrosion resistance and maintains a clean, rust-free appearance for added value and longevity.
• OE Style Finish: Smooth, plain rotor surface ideal for drivers seeking a clean, factory look with upgraded performance benefits.

Construction & Design:

The rotor is precision cast from DBA’s proprietary XG-150 high carbon alloyed iron, formulated to optimize strength and heat dissipation. The advanced Kangaroo Paw ventilation design incorporates a unique pattern of diamond and teardrop-shaped pillars that significantly increase airflow through the rotor, reducing operating temperatures and minimizing brake fade during extended or aggressive braking.

DBA’s Thermal Stability Profiling process further enhances the rotor’s durability by relieving internal stresses and improving resistance to cracking and warping. The combination of these engineering advancements results in a rotor that maintains consistent performance and longevity even under demanding driving conditions.

Installation & Fitment:

This rotor is designed as a direct bolt-on replacement for the rear brake system of Dodge Durango models from 2011 through 2020 equipped with vented rear discs. Installation requires no modifications, ensuring a straightforward upgrade that fits precisely with existing brake components. It is recommended to verify your vehicle’s brake package and measure existing rotors to confirm compatibility before purchase.

Please note that due to multiple brake package variations offered by manufacturers, fitment should be used as a guideline. For exact fitment confirmation, consult DBA’s Part Finder tool using the provided SKU.
