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

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating on both the disc surface and the hat. This full coating helps prevent rust and corrosion, which can degrade braking performance and rotor longevity. The rotors in this line are designed to meet or exceed OEM specifications, making them suitable replacements for heavy-duty Ford trucks like the F-250 Super Duty, F-350 Super Duty, and Excursion.

Product Details and Specifications

This vented disc brake rotor features a smooth surface finish and pillar-style vanes that enhance airflow to reduce heat buildup during braking. The rotor measures 13.031 inches in outside diameter and 5.65 inches in overall height, with a center hole diameter of 4.921 inches (125 mm) to ensure proper hub fitment. The rotor thickness is nominally 1.496 inches, with a discard thickness of 1.417 inches, indicating when replacement is necessary. The rotor includes an ABS tone ring, ensuring compatibility with factory ABS systems on compatible Ford models. The stud thread diameter is 14 mm with a bolt thread pitch of 1.5 mm, and the rotor mounts to the hub and rotor assembly using 8 lug holes arranged on a 6.693-inch bolt circle diameter.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Excursion and Super Duty trucks
• Addresses rotor corrosion and rust issues with full coating protection
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Restores ABS sensor functionality with included tone ring
• Ensures proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor is installed on compatible Ford Excursion, F-250 Super Duty, or F-350 Super Duty models. Verify the rotor thickness before installation and replace if below discard thickness. Clean the hub surface before mounting to prevent runout. Use proper torque specifications on lug nuts to avoid rotor warping. The included ABS tone ring should be handled carefully to maintain sensor accuracy.
