DBA 4000 Series Plain Rotor (REAR)

Dodge Durango / Jeep Grand Cherokee V6 RWD ONLY 2011 - 2026

DBA42636

Overview:

The DBA 4000 Series Plain Rotor is a high-performance direct replacement rear brake rotor designed specifically for the Dodge Durango models from 2011 to 2020 equipped with solid rear discs. Engineered for drivers who demand enhanced braking performance beyond standard OEM levels, this rotor delivers reliable stopping power and durability under a variety of driving conditions. Whether you're tackling daily driving, towing, or spirited driving, the 4000 Series rotor offers improved heat management and consistent braking feel.

Manufactured by DBA, a leader in performance braking technology, this rotor is ideal for enthusiasts seeking a balance of OE-style appearance and upgraded braking capability without the complexity of drilled or slotted designs.

Key Features:

The DBA 4000 Series Plain Rotor incorporates advanced engineering and materials to provide superior braking performance and longevity. Key features include:

• Kangaroo Paw Ventilation System: Features 144 diamond and teardrop-shaped ventilation 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 conditions.
• Thermal Stability Profiling (TSP): A proprietary heat treatment process that enhances rotor durability and resistance to thermal fatigue.
• Thermographic Temperature Monitoring: Heat-sensitive paint markings change color at specific temperature thresholds, providing a visual indicator of peak braking temperatures and rotor health.
• Paint Protection on Non-Friction Areas: Corrosion-resistant coating prevents rust formation and maintains a clean, professional appearance.
• OE Style Finish: Smooth, plain rotor surface ideal for drivers who prefer a stock look while benefiting from performance upgrades.

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. The material's increased thermal capacity minimizes the risk of rotor warping and cracking, extending the service life of both the rotor and brake pads. The Kangaroo Paw ventilation design enhances airflow through the rotor, significantly improving heat dissipation and reducing brake fade during demanding driving conditions.

Each rotor undergoes Thermal Stability Profiling (TSP), a heat treatment process that stabilizes the metallurgy to maintain consistent performance over time. The smooth, plain surface finish offers a clean appearance while providing reliable friction characteristics compatible with a wide range of brake pads.

Installation & Fitment:

This rotor is a direct bolt-on replacement for the rear solid disc brake setup on Dodge Durango models from 2011 through 2020. No modifications are required for installation when replacing compatible OEM rotors. It is recommended to verify your vehicle's brake package and measure existing rotor dimensions to ensure proper fitment, as multiple brake configurations may exist for the same model year.

For precise fitment confirmation, use DBA's Part Finder tool by entering the SKU DBA42636 under the "Part Number Search" tab. Proper installation by a qualified technician is advised to maintain optimal braking performance and safety.
