About the Power Stop - Rear Genuine Geomet Coated Rotor Line

This Power Stop product line focuses on rear rotors featuring a genuine Geomet coating, which provides enhanced corrosion resistance compared to standard rotors. The coating helps maintain rotor integrity and appearance over time, especially in environments prone to rust. These rotors are designed as standard replacement parts, ensuring compatibility and performance for Ram ProMaster vehicles requiring reliable rear braking components.

Detailed Product Description

The AR83113EVC rotor is a full cast, vented disc brake rotor engineered to meet the braking demands of Ram ProMaster vans. Its vented design improves airflow, reducing heat buildup during braking and helping to prevent brake fade. The rotor measures 300 mm in outside diameter with a nominal thickness of 22.10 mm, ensuring it meets OEM specifications. The Geomet coating provides a protective layer against rust and corrosion, extending the rotor's service life. With a smooth braking surface and 5 lug holes on a 130 mm bolt circle diameter, this rotor offers a precise fit and consistent braking performance.

Common Applications and Issues Addressed

• Replacement for worn or warped rear rotors on Ram ProMaster 1500, 2500, 3500, and ProMaster EV
• Corrosion damage due to exposure to moisture and road salt
• Brake fade caused by excessive heat buildup during heavy braking
• Uneven braking or vibration from rotor surface irregularities
• Maintaining OEM braking performance and safety standards

Installation Notes and Tips

Ensure the rotor is installed on the rear axle of compatible Ram ProMaster models as specified. Verify the rotor thickness before installation; replace if below the discard thickness of 19.90 mm. Clean the rotor surface to remove any protective coating residue before mounting brake pads. Confirm the 5-lug bolt pattern with a 130 mm bolt circle diameter matches the vehicle hub. Proper torque specifications should be followed to avoid rotor warping.
