Centric 320.67062F Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.67062F, is a rear vented rotor built to match OE performance while adding corrosion resistance on non-mating surfaces. It is a fitment-specific rotor for select Dodge Ram 1500, Ram 2500, and Ram 3500 applications, including 2006-2008 Ram 1500 models with the Mega Cab option.

Centric’s GCX Full Coating line uses an application-specific coating pattern and OE-matched metallurgy to support consistent braking performance and long-term appearance. This rotor is fully coated, with a coated hat finish and smooth surface type for a clean, corrosion-resistant finish.

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are engineered for OE-style fit and braking characteristics, with RS200 coating applied to non-mating surfaces to help resist rust and corrosion. The GCX line also uses application-specific coating patterns and metallurgy selections to align with the brake pad friction type and the vehicle’s OEM rotor profile. Part number 320.67062F is part of this GCX Full Coating family.

Compatible Applications

• Fits 2006-2008 Dodge Ram 1500, rear; will only fit models with Mega Cab option.
• Fits 2003-2008 Dodge Ram 2500, rear.
• Fits 2003-2008 Dodge Ram 3500, rear.

This part cross-references Raybestos Brakes 780139FZN for the same application.

Common Replacement Reasons

• Rear rotor rust or corrosion on exposed surfaces
• Brake pulsation from rotor wear or thickness variation
• Reduced braking consistency from worn rear rotors
• Noise or vibration during rear brake service
• Need for an OE-style replacement rotor for Dodge Ram 1500, Ram 2500, or Ram 3500

Installation Notes and Tips

Confirm rear axle application, rotor dimensions, and lug count before installation. For 2006-2008 Dodge Ram 1500, this rotor is limited to Mega Cab models. Inspect pads, calipers, and hub surfaces during service, and verify the rotor seats correctly on the hub before final torque.

Quality Assurance

Centric designs the GCX rotor line to align with OE performance targets and vehicle-specific metallurgy requirements. The RS200-coated finish on non-mating surfaces is intended to improve corrosion resistance and maintain a cleaner appearance over time.
