About the Element3; Coated Rotor Product Line
The Element3; Coated Rotor line by Raybestos features rotors with a protective coating designed to resist corrosion and extend rotor life. This coating helps maintain rotor surface integrity and reduces the risk of rust, which is particularly beneficial for trucks like the Dodge Ram 2500 and 3500 that may be exposed to harsh driving conditions.
Technical Specifications and Features
This disc brake rotor is vented to improve heat dissipation during braking, reducing the risk of brake fade under heavy loads. The drum-in-hat design integrates a parking brake drum within the rotor, providing a compact and efficient braking solution. With eight mounting bolt holes and stud/lug hole quantity, the rotor ensures secure attachment to the vehicle hub. The precise dimensions, including the nominal and discard thicknesses, help maintain braking performance and safety standards.
Applications and Problem Solving
- Replacement for worn or warped rotors on Dodge Ram 2500 and Ram 3500
- Addresses brake fade caused by overheating during heavy towing or hauling
- Solves issues related to rotor corrosion and surface degradation
- Restores proper parking brake function with integrated drum-in-hat design

Installation Notes and Tips
Ensure the rotor is installed on compatible Dodge Ram 2500 or 3500 models matching the specified bolt pattern and dimensions. Verify the mounting bolt hole circle diameter and center hole diameter for proper fitment. It is recommended to measure the existing rotor thickness and compare it to the discard thickness of 1.118 inches (28.400 mm) to determine if replacement is necessary. Proper torque specifications should be followed during installation to maintain safety and performance.
