Product Details

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line is built around vehicle-specific metallurgy and coating strategy. Centric matches rotor construction to OEM-style carbon alloy profiles, using enhanced carbon or high carbon formulations depending on the application. For the Ford F-350 Super Duty rear rotor, that means a direct-fit replacement focused on consistent braking feel, corrosion protection, and long service life in demanding truck use. The 320.65070F rotor measures 326.000 mm in outside diameter, 30.000 mm nominal thickness, 112.800 mm overall height, and 120.100 mm center hole diameter.

This part cross-references Raybestos Brakes (e.g., 66824FZN) for the same application. Compatible With 1999-2004 Ford F-350 Super Duty rear brake service, including heavy duty dual rear wheels. The Centric GCX line is designed for broad coverage across late-model vehicles, and this rotor is one of the application-specific options for the Ford F-350 Super Duty platform.

What It Helps Address

• Rear brake rotor rust on exposed surfaces
• Brake pulsation caused by worn or below-spec rotors
• Uneven braking performance from rotor wear
• Corrosion buildup on truck brake components
• Replacement needs for rear brake service on Ford F-350 Super Duty models

Installation Notes

Verify rotor dimensions, hub fit, and rear axle configuration before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect pads and caliper hardware for wear before completing brake service. Because this rotor is vented and fully coated, avoid damaging the coated non-mating surfaces during handling and installation. Confirm the part number 320.65070F against the vehicle’s rear brake specification before ordering.

Quality Assurance

Centric designs GCX rotors to match OE performance targets while improving resistance to rust and corrosion through its RS200 coating on non-mating surfaces. The GCX FC product line uses application-specific coating patterns and rotor metallurgy to align with the brake system’s friction requirements. For buyers searching for a rear brake rotor for 1999-2004 Ford F-350 Super Duty, part number 320.65070F provides a direct-fit, corrosion-protected replacement option.
