Detailed Product Description

This Centric GCX Elemental Protection Disc Brake Rotor is a vented rotor featuring a straight vane design that promotes efficient heat dissipation during braking, helping to reduce brake fade. The rotor’s fully coated disc and hat surfaces provide a protective barrier against corrosion, which is especially beneficial for Jeep Cherokee, Comanche, Wagoneer, and Wrangler vehicles often exposed to harsh environments. With a nominal thickness of 0.874 inches and a discard thickness of 0.815 inches, this rotor maintains structural integrity and performance throughout its service life. The floating disc mounting design allows for slight movement to accommodate thermal expansion, contributing to even pad wear and consistent braking feel.

About the Centric GCX Elemental Protection Disc Brake Rotors - Full Coating Line
