Centric 320.67040F Disc Brake Rotor - Front

Centric GCX Front Brake Rotor for Ram Vans

Centric GCX Elemental Protection Disc Brake Rotor - Full Coating, part number 320.67040F, is a front vented rotor engineered to match OE braking performance while adding corrosion resistance on non-mating surfaces. It is built for 1998 Dodge B2500, 1998 Dodge B3500, and 1999-2003 Dodge Ram 2500 Van and Ram 3500 Van front brake applications.

The GCX rotor line uses Centric’s application-specific coating approach and metallurgy selection to align with the vehicle’s original brake pad friction profile and OEM material requirements. For Dodge Ram 2500 Van, Dodge Ram 3500 Van, Dodge B2500, and Dodge B3500 front brake service, this rotor is built for smooth operation, consistent fit, and long-term surface protection.

Product Details

Centric GCX Elemental Protection Disc Brake Rotors are built to deliver OE-level braking characteristics with added protection on exposed surfaces. This rotor measures 12.815 inches in outside diameter, 4.587 inches in overall height, and 1.248 inches nominal thickness, with a discard thickness of 1.181 inches. It uses a straight vane design and an 8-lug bolt pattern with a 6.500-inch bolt circle diameter. The fully coated finish helps resist rust on the hat and non-mating surfaces, which is useful for maintaining appearance and service life in demanding driving conditions.

Common Reasons for Replacement

• Brake pulsation or vibration from rotor wear
• Rust buildup on the rotor hat or non-contact surfaces
• Reduced braking smoothness during front brake service
• Rotor scoring, thickness loss, or heat-related wear
• ABS-related service needs where the tone ring is part of the assembly

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and bolt pattern before installation. Clean the hub mounting surface thoroughly to help prevent runout concerns, and inspect pads, calipers, and hardware condition during front brake service. For best results, follow the vehicle manufacturer’s bedding procedure after installation. Fits 1998 Dodge B2500, front. Fits 1998 Dodge B3500, front. Fits 1999-2003 Dodge Ram 2500 Van, front.
