2005–2024 Dodge Magnum, Chrysler 300, Dodge Challenger, Dodge Charger 5.7L Hemi

Part #: DBA42439XS

Overview

The DBA XS 4000 Series Rear Brake Rotors are engineered to deliver superior braking performance for a range of Dodge and Chrysler vehicles equipped with the 5.7L Hemi engine from 2005 through 2024. Designed for enthusiasts who demand enhanced stopping power and reliability, these rotors feature a drilled and slotted design that improves heat dissipation and reduces brake fade during aggressive driving or towing scenarios.

Ideal for daily drivers and performance enthusiasts alike, the XS 4000 Series rotors provide a noticeable improvement in brake pedal feel and overall braking confidence. Their aggressive styling also adds a visual upgrade to your vehicle’s braking system, complementing the muscular aesthetics of Dodge and Chrysler muscle cars and sedans.

Key Features

DBA’s XS 4000 Series rotors incorporate advanced technology and design elements to ensure consistent performance and durability:

• Constructed from High Carbon Alloyed Iron (XG-150) for enhanced strength and thermal conductivity
• Drilled and slotted surface pattern improves heat dissipation and reduces brake fade
• Thermal Stability Profiling (TSP) process minimizes warping and cracking under extreme heat cycles
• Improved brake pedal feel for more precise control and modulation
• Corrosion-resistant coating extends rotor life and maintains appearance
• Sold individually; recommended to purchase two for a complete rear axle upgrade
• Designed specifically for rear brake applications on 5.7L Hemi-powered vehicles
• Compatible with OEM brake pads and calipers for straightforward installation

Construction & Design

The XS 4000 Series rotors are manufactured using DBA’s proprietary High Carbon Alloyed Iron (XG-150), which combines the durability of cast iron with enhanced carbon content to improve heat tolerance and reduce cracking. This material choice ensures the rotors maintain structural integrity even under repeated high-temperature braking events.

Each rotor undergoes Thermal Stability Profiling (TSP), a specialized heat treatment process that stabilizes the rotor’s internal structure. This reduces the risk of warping and extends the rotor’s service life, making it ideal for both spirited street driving and occasional track use.

The drilled holes and precision-machined slots are strategically placed to optimize airflow and brake pad cleaning, which helps maintain consistent friction and reduces the buildup of brake dust and gases.

Installation & Fitment

These rear brake rotors are designed as direct replacements for the factory rotors on compatible Dodge Magnum, Chrysler 300, Dodge Challenger, and Dodge Charger models equipped with the 5.7L Hemi engine from 2005 to 2024. Installation requires no modifications and fits with existing OEM brake pads and calipers.

Note that rotors are sold individually; it is recommended to purchase two rotors to replace both rear wheels for balanced braking performance. Professional installation is advised to ensure proper torque specifications and brake system safety.
