Centric 320.62042F Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.62042F, is a front vented rotor built for OE-style braking performance and corrosion resistance. It is a strong match for heavy-duty Chevrolet K2500, Chevrolet K3500, GMC K2500, GMC K3500, and Dodge Ram 2500 front brake applications where rotor fit, finish, and metallurgy matter.

Centric’s GCX Full Coating line uses a fully coated disc finish and coated hat to help protect non-mating surfaces from rust while maintaining a smooth braking surface. The 320.62042F is application-specific, with rotor metallurgy and coating patterns selected to align with the brake pad friction type and OEM-style requirements.

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are engineered to match OE performance while adding corrosion protection on exposed surfaces. The GCX Full Coating design is intended for drivers who want a rotor that maintains a cleaner appearance over time and better resists rust on the hat and non-mating areas. Part number 320.62042F follows Centric’s application-specific approach to coating and metallurgy for a more precise fit to the vehicle’s original brake setup.

What This Rotor Helps Address

• Front brake rotor rust on exposed surfaces
• Brake pulsation caused by worn or out-of-spec rotors
• Reduced braking consistency from rotor wear
• Fitment issues on 8-lug heavy-duty truck and SUV brake setups
• Premature corrosion on vehicles used in wet or salted-road conditions

Installation Notes and Tips

Verify rotor dimensions, hub style, and bolt pattern before installation. This rotor uses a behind-the-hub mounting design and is intended for front axle applications only. Check pad condition, caliper operation, and hub surface cleanliness during service to help ensure even rotor contact and proper brake performance. For 1990-2000 Chevrolet K3500 and GMC K3500 applications, confirm the Single Rear Wheel configuration noted in the fitment data.

Quality Assurance

Centric designs the GCX line to align with OEM metallurgical profiles and OE-style braking requirements. The RS200 coating on non-mating surfaces is used to improve corrosion resistance and help the rotor maintain its appearance and service life over time. This part number, 320.62042F, is built as a direct-fit front rotor for the listed Chevrolet, GMC, and Dodge applications.
