Product Details

The Centric GCX line is engineered around vehicle-specific metallurgy and coating coverage to match original equipment requirements. For this rotor, Centric uses its RS200 finish on non-mating surfaces to help protect the rotor from rust and corrosion while preserving braking surface contact where needed. The GCX FC design is a practical choice for drivers servicing Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, or GMC Savana 3500 front brakes and looking for a direct-fit replacement with a coated appearance.

This part number, 320.66049F, is listed for 2001-2002 Chevrolet Express 2500, front; 2001-2002 Chevrolet Express 3500, front; 2001-2002 GMC Savana 2500, front; and 2001-2002 GMC Savana 3500, front. It cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front brake rotor rust on exposed surfaces
• Corrosion buildup on vehicles used in wet or salted-road conditions
• Brake pulsation caused by worn or below-spec rotors
• Uneven rotor wear from replacement parts that do not match OE metallurgy
• Loss of braking consistency on high-use Chevrolet Express and GMC Savana vans

Installation Notes

Verify rotor dimensions, hub fitment, and 8-lug bolt pattern before installation. This rotor is for front use and is listed for hub-and-rotor mounting with no ABS tone ring and no bearings included. Confirm the vehicle configuration matches the listed applications, including the 8-lug brake setup on Chevrolet Express 2500 and GMC Savana 2500, and the single rear wheel configuration noted for Chevrolet Express 3500 and GMC Savana 3500.

Quality Assurance

Centric designs GCX rotors to align with OE performance targets and vehicle-specific metallurgy profiles. The fully coated finish and application-specific coating pattern are intended to support long-term corrosion resistance and consistent fitment across the listed applications.
