Product Line Details

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating to resist rust and corrosion. This full coating extends the rotor's service life and maintains consistent braking performance, especially in environments prone to moisture and road salt exposure. The 320.58018F rotor benefits from this coating technology, making it suitable for Jeep Wrangler and Wrangler JK owners seeking durable replacement rotors.

Technical Specifications and Features

This disc brake rotor features a vented design with 47 straight vanes, which enhances airflow and heat dissipation during braking. The rotor's nominal thickness is 1.102 inches (28.000 mm), with a discard thickness of 1.039 inches (26.400 mm), ensuring safe replacement intervals. The rotor measures 13.071 inches (332.000 mm) in outside diameter and has an overall height of 2.173 inches (55.200 mm). The floating disc mounting system helps reduce stress and improve rotor longevity. Both the disc and hat are fully coated to protect against corrosion, and the smooth surface finish supports consistent pad contact and braking performance.

Compatible Applications and Common Issues Addressed

• Replacement rotor for Jeep Wrangler and Wrangler JK models
• Resolves rotor corrosion and rust buildup
• Addresses brake pulsation caused by uneven rotor wear
• Improves heat dissipation to reduce brake fade
• Restores braking performance after rotor thickness falls below discard limits

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness specifications. The 320.58018F rotor requires a 5-lug wheel hub with a 5.000 inch (127.000 mm) bolt circle diameter. No ABS tone ring or bearings are included, so verify compatibility with your vehicle's existing components. Proper torque specifications should be followed when mounting the rotor to avoid warping. Cleaning the rotor surface before installation is recommended to remove any protective coatings or residues.
