Element3; Coated Rotor Product Line Details

The Element3; Coated Rotor line by Raybestos focuses on corrosion resistance and extended rotor life through a proprietary coating process. This coating helps protect the rotor surface from rust and environmental damage, which is particularly beneficial for vehicles like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 that operate in demanding conditions. The 56999FZN rotor maintains structural integrity while providing consistent braking performance over time.

Technical Specifications and Features

This disc brake rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade. The nominal thickness of 1.500 inches (38.100 mm) ensures sufficient material for durability, while the discard thickness of 1.437 inches (36.500 mm) indicates when replacement is necessary. The rotor’s overall height of 3.510 inches (89.150 mm) and outside diameter of 12.795 inches (325.000 mm) are engineered for exact fitment on compatible Chevrolet and GMC heavy-duty trucks. The eight mounting bolt holes and corresponding bolt circle diameter of 6.500 inches (165.100 mm) provide secure installation, and the center hole diameter of 4.650 inches (118.100 mm) ensures proper alignment.

Applications and Problem Solving

• Replacement for worn or warped rotors on Chevrolet Avalanche 2500 and GMC Sierra 3500
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves braking consistency in heavy-duty Silverado 2500 HD and Express 3500 trucks
• Helps prevent rust-related rotor degradation in vehicles exposed to harsh environments
• Supports safe braking performance under heavy load conditions

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness to confirm it meets or exceeds the discard thickness of 1.437 inches (36.500 mm). Use proper torque specifications for the eight mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. The vented design requires proper clearance, so confirm compatibility with your specific Chevrolet or GMC model.
