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

This rotor is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating enhances corrosion resistance without compromising braking performance. The vented rotor design helps maintain optimal operating temperatures, reducing the risk of brake fade during extended use. The AR8390EVC rotor meets specifications for front brake replacement on Ram ProMaster City models, ensuring proper fit and function.

Technical Specifications and Features

The AR8390EVC rotor features a nominal thickness of 28.00 mm and an overall height of 45.80 mm, with a discard thickness of 0.00 mm indicating it is new and ready for installation. The rotor’s outside diameter measures 305.00 mm (12.00 inches), suitable for the front brake assembly of the Ram ProMaster City. It includes five lug holes arranged on a 98.00 mm bolt circle diameter, matching the vehicle’s mounting requirements. The vented design improves heat dissipation, which is critical for maintaining braking efficiency under load. The Geomet coating provides a protective layer against rust and corrosion, extending the rotor’s service life in various driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped front disc brake rotors on Ram ProMaster City
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore braking performance affected by rotor corrosion or rust buildup
• Improves heat management to reduce brake fade during heavy braking
• Suitable for vehicles experiencing reduced stopping power due to rotor wear

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness meets or exceeds the nominal thickness of 28.00 mm. Use proper torque specifications for the five lug nuts on the 98.00 mm bolt circle diameter. It is recommended to inspect brake pads and replace them if worn to maintain optimal braking performance. The vented design requires proper clearance in the brake caliper assembly, so confirm compatibility with the Ram ProMaster City front brake system.
