Product Line Details: Centric GCX Elemental Protection

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a full protective coating to resist rust and corrosion. This coating extends rotor life and maintains consistent braking performance, especially in environments prone to moisture and road salt exposure. The full coating on both the disc and hat surfaces helps preserve the rotor’s structural integrity and appearance over time.

Technical Description and Specifications

This disc brake rotor features a vented design with straight vanes to facilitate efficient heat dissipation during braking, reducing the risk of brake fade. The rotor’s nominal thickness is 1.398 inches (35.500 mm), with a discard thickness of 1.320 inches (33.530 mm), ensuring safe replacement intervals. The rotor measures 12.854 inches (326.500 mm) in outside diameter and has an overall height of 4.016 inches (102.000 mm). It includes 8 stud/lug holes with a diameter of 0.665 inches (16.900 mm) and a mounting bolt hole circle diameter of 6.500 inches (165.100 mm). The floating disc mounting design allows for slight movement to reduce stress and improve rotor longevity. The smooth surface finish supports consistent pad contact and braking efficiency.

Applications and Problem Solving

• Replacement rotor for worn or warped disc brakes on Dodge Ram 2500 and Ram 3500
• Addresses corrosion and rust issues with fully coated surfaces
• Improves heat management to reduce brake fade during heavy towing or hauling
• Restores braking performance compromised by rotor thickness below discard limits
• Suitable for trucks requiring vented rotors with floating mounting design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.320 inches (33.530 mm) before installation. Clean the hub surface to prevent uneven rotor mounting. Use proper torque specifications for the 8 lug nuts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s brake system components. The floating mounting design requires correct alignment to function properly.
