DBA 4000 Series Plain Rotor (Front)

2011–2020 Jeep Grand Cherokee with 330mm Front Rotor (Excluding SRT8)

DBA42634

Overview:

The DBA 4000 Series Plain Rotor is a high-performance direct replacement brake rotor designed specifically for the front brakes of Jeep Grand Cherokee models from 2011 to 2020 equipped with 330mm front rotors, excluding the SRT8 variant. Engineered for drivers seeking enhanced braking performance beyond standard OEM levels, this rotor delivers reliable stopping power and improved heat management for everyday driving and spirited use.

Crafted to meet the demands of both street and light track applications, the 4000 Series rotor offers a balance of durability, thermal stability, and consistent braking feel. It is an ideal upgrade for Jeep owners who want to maintain OEM fitment while benefiting from advanced metallurgy and ventilation technology.

Key Features:

The DBA 4000 Series Plain Rotor incorporates innovative design and materials to optimize braking performance and rotor longevity. 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: Specially formulated cast iron alloy that improves thermal capacity, reducing the risk of warping and cracking under extreme heat.
• 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, allowing drivers to monitor peak braking temperatures and rotor condition.
• Paint Protection on Non-Friction Surfaces: Prevents corrosion and rust formation, maintaining rotor appearance and extending service life.
• OE Style Plain Rotor Finish: Smooth surface finish ideal for drivers seeking a clean, factory look while upgrading braking performance.

Construction & Design:

The DBA 4000 Series rotor is precision cast from XG-150 high carbon alloyed iron, a material known for its superior thermal conductivity and strength. This alloy is specifically engineered to withstand the intense heat generated during aggressive braking without compromising structural integrity. The rotor undergoes Thermal Stability Profiling (TSP), a heat treatment process that enhances its resistance to cracking and warping, ensuring consistent performance over time.

The patented Kangaroo Paw ventilation system is a standout design feature, incorporating a unique pattern of ventilation pillars that significantly increase airflow and heat dissipation. This design reduces brake fade and mechanical damage, contributing to longer rotor and pad life. The rotor’s non-friction surfaces are coated with protective paint to prevent rust and corrosion, preserving both function and aesthetics.

Installation & Fitment:

This rotor is a direct bolt-on replacement for the front brakes of Jeep Grand Cherokee models from 2011 through 2020 equipped with 330mm front rotors, excluding the SRT8. Installation requires no modifications and fits with existing brake pads and hardware designed for this rotor size. It is recommended to verify your vehicle’s rotor dimensions and brake package before purchase to ensure compatibility.

Due to variations in brake packages offered by manufacturers, measuring your current rotors and comparing them with DBA’s specifications is advised. This ensures the correct fitment and optimal braking performance.
