DBA XS 4000 Series Rear Gold Brake Rotors (Drilled & Slotted)

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

Part #: DBA42439BLKXS

Overview

The DBA XS 4000 Series Rear Gold Brake Rotors are engineered for drivers who demand superior braking performance and reliability from their 5.7L Hemi-powered Chrysler and Dodge vehicles. Designed specifically for models including the Chrysler 300, Dodge Challenger, Dodge Charger, and Dodge Magnum from 2005 through 2024, these rotors enhance stopping power while maintaining excellent durability under extreme conditions.

Featuring a drilled and slotted design, these rotors improve heat dissipation and reduce brake fade during aggressive driving or towing scenarios. Ideal for enthusiasts and daily drivers alike, the DBA XS 4000 Series rotors deliver consistent pedal feel and enhanced braking confidence, all while adding a striking gold finish that complements your vehicle’s performance look.

Key Features

DBA’s XS 4000 Series Rear Gold Brake Rotors incorporate advanced technology and design elements to optimize braking efficiency and longevity:

• Constructed from High Carbon Alloyed Iron (XG-150) for superior strength and thermal conductivity
• Drilled and slotted surface pattern improves water, dust, and gas evacuation for cleaner pad contact
• Thermal Stability Profiling (TSP) process ensures consistent rotor geometry after repeated extreme heat cycles
• Gold zinc plating provides corrosion resistance and a distinctive appearance
• Designed to reduce brake fade and improve pedal feel during high-performance or heavy-duty use
• Sold individually; recommended to purchase two for complete rear axle replacement
• Precision balanced and machined for smooth operation and minimal vibration
• Compatible with factory brake pads and calipers for straightforward installation

Construction & Design

DBA’s XS 4000 Series rotors are manufactured using a proprietary High Carbon Alloyed Iron blend known as XG-150. This material offers enhanced tensile strength and improved thermal conductivity compared to standard cast iron, allowing the rotors to withstand the intense heat generated during aggressive braking without warping or cracking.

The Thermal Stability Profiling (TSP) process is a critical engineering step that subjects each rotor to controlled heat cycles, stabilizing the metal’s internal structure. This ensures the rotor maintains its flatness and performance characteristics even after repeated heavy braking events. The drilled and slotted design further aids in heat dissipation and helps maintain clean pad surfaces for consistent braking power.

To protect against corrosion and extend service life, the rotors feature a durable gold zinc plating that also enhances the visual appeal of the braking system.

Installation & Fitment

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

Each rotor is sold individually; it is recommended to purchase two rotors to replace both sides of the rear axle for balanced braking performance and safety. Professional installation is advised to ensure proper torque specifications and brake system function.
