Product Line Details: Centric GCX Elemental Protection

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating that extends rotor life by preventing rust and corrosion. This full coating covers both the braking surface and the hat area, ensuring comprehensive protection against environmental elements. This product line is engineered to maintain consistent braking performance while reducing the need for frequent rotor replacement.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes that promote efficient heat dissipation during braking, reducing the risk of brake fade. The rotor has a nominal thickness of 1.181 inches (30.000 mm) and a discard thickness of 1.122 inches (28.500 mm), indicating when the rotor should be replaced to maintain safe braking. The outside diameter measures 13.780 inches (350.000 mm), suitable for the specified Nissan and INFINITI models. The rotor mounting uses a floating disc design, which helps accommodate thermal expansion and improves rotor alignment. The smooth surface finish ensures consistent pad contact and braking performance.

Compatible Vehicles and Applications

• Replacement disc brake rotor for Nissan Armada models
• Compatible with Nissan TITAN trucks requiring vented rotors
• Fits INFINITI QX56 SUVs needing full coating rotors for corrosion resistance
• Ideal for addressing rotor wear, corrosion, and heat-related braking issues
• Suitable for vehicles experiencing brake noise or vibration due to rotor surface wear

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.122 inches (28.500 mm) before installation. Clean the hub surface thoroughly to prevent uneven rotor mounting. Use proper torque specifications on the 6 lug studs with 0.531 inch (13.500 mm) diameter holes. Since this rotor does not include bearings or ABS tone rings, verify compatibility with your vehicle’s existing components. The floating disc mounting requires careful alignment during installation to maintain optimal rotor performance.
