Product Line Details: Power Stop - Rear Genuine Geomet Coated Rotor

This rotor is part of the Power Stop - Rear Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating enhances corrosion resistance compared to standard rotors, extending service life especially in harsh environments. The vented rotor design improves heat dissipation, helping maintain braking efficiency during heavy-duty use typical for Dodge Ram 2500 and 3500 trucks.

Technical Specifications and Features

The AR8374EVC rotor features a nominal thickness of 34.20 mm and a discard thickness of 32.40 mm, ensuring it meets OEM standards for wear limits. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup and minimizing brake fade. The overall diameter measures 358.30 mm (14.10 inches), with an overall height of 124.90 mm (4.90 inches). The rotor mounts using an 8-lug pattern with a bolt hole circle diameter of 165.10 mm and a stud/lug hole diameter of 6.50 mm.

Applications and Problem Solving

• Replacement for worn or warped rear rotors on Dodge Ram 2500 and Ram 3500
• Addresses brake noise and vibration caused by rotor surface irregularities
• Helps reduce rust and corrosion-related rotor degradation
• Improves braking consistency under heavy load or towing conditions
• Supports extended rotor life in environments prone to moisture and road salt

Installation Notes and Tips

When installing the AR8374EVC rotor, ensure the mounting surface is clean and free of debris to maintain proper rotor alignment. Verify the rotor thickness before installation to confirm it is above the discard thickness of 32.40 mm. Use appropriate torque specifications for the 8-lug mounting pattern to avoid warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
