DBA 4000 Series Rotor

2009–2022 Dodge Challenger 5.7L

DBA42438

Overview:

The DBA 4000 Series Rotor is a premium front brake rotor designed specifically for the Dodge Challenger models equipped with the 5.7L engine from 2009 through 2022. Engineered as a direct replacement for your factory rotors, this rotor offers enhanced braking performance and durability for drivers seeking an upgrade beyond standard OEM components. Whether you are a daily driver, weekend enthusiast, or participate in controlled race events, the 4000 Series delivers reliable stopping power with improved heat management and longevity.

Constructed with advanced materials and innovative design features, this rotor is ideal for those who demand consistent braking performance under high-stress conditions without compromising on fitment or appearance.

Key Features:

The DBA 4000 Series Rotor incorporates cutting-edge technology to maximize braking efficiency and rotor lifespan. Key features include:

• Kangaroo Paw Ventilation System: Utilizes 144 diamond and teardrop-shaped pillars to 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 material that withstands extreme heat and stress, reducing warping and cracking for extended rotor life.
• Thermal Stability Profiling (TSP): A proprietary heat treatment process that improves rotor durability and performance under repeated heavy braking.
• Thermographic Temperature Monitoring: Heat-sensitive paint markings change color at specific temperature thresholds, providing visual feedback on rotor temperature and fatigue.
• Paint Protection on Non-Friction Areas: Prevents corrosion and rust formation, maintaining a clean, attractive appearance over time.
• Smooth OE Style Finish: The 4000 Series HD variant offers a factory-like appearance, ideal for drivers who want upgraded performance without altering the vehicle’s original look.

Construction & Design:

The rotor is cast from DBA’s proprietary XG-150 high carbon alloyed iron, which is engineered to handle the intense heat generated during aggressive braking. This material, combined with the Thermal Stability Profiling process, ensures the rotor maintains structural integrity and resists warping and cracking over extended use. The innovative Kangaroo Paw ventilation design optimizes airflow through the rotor, significantly improving heat dissipation and reducing brake fade. This advanced engineering results in a rotor that not only performs better but also lasts longer than standard OEM rotors.

Installation & Fitment:

This rotor is designed as a direct bolt-on replacement for the front brakes of Dodge Challenger models with the 5.7L engine from 2009 to 2022. While vehicle fitment is provided as a guide, it is recommended to verify compatibility by measuring your existing brake discs and pads and comparing them with DBA’s specifications via their Part Finder tool. Installation requires standard brake service procedures and no modifications to the vehicle’s braking system. Proper installation ensures optimal performance and safety.

What's Included:

• One front DBA 4000 Series Rotor (Part # DBA42438)

Ideal For:

This rotor is perfect for Dodge Challenger owners looking to upgrade their braking system with a high-performance, durable rotor that offers improved heat management and reduced brake fade. It suits daily drivers who want enhanced safety and reliability, as well as enthusiasts who participate in spirited driving or controlled racing events where consistent braking performance is critical.
