Detailed Product Description

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating (part number 320.42111F) are engineered to meet the braking demands of full-size SUVs such as the Nissan Armada and Infiniti QX56 and QX80. These rotors feature a fully coated disc and hat finish that protects against rust and corrosion, which is critical for vehicles exposed to harsh weather or road conditions. The vented rotor design with straight vanes enhances airflow, helping to dissipate heat efficiently and reduce brake fade during extended use.

With a nominal thickness of 1.181 inches and a discard thickness of 1.122 inches, these rotors maintain structural integrity and performance throughout their service life. The smooth surface finish ensures consistent pad contact and braking response. The floating disc mounting system allows for slight movement to reduce stress and improve rotor longevity. The rotor’s dimensions, including a 13.780-inch outside diameter and 6 lug holes, are specifically designed for compatibility with Nissan Armada and Infiniti QX56 and QX80 models.
