Raybestos 581033FZN Element3 Grey Fusion Coated Rear Disc Brake Rotor

The Raybestos 581033FZN Element3 is a solid rear disc brake rotor engineered with Rust Prevention Technology (RPT) for superior corrosion resistance. Fully coated on every surface — including the cooling vanes — with Raybestos' proprietary Grey Fusion 4.0 coating, this rotor is built to withstand the harshest conditions including rain, road salt, and snow.

Developed from original equipment (OE) samples and manufactured using G3000-qualified cast iron, the 581033FZN delivers precise form, fit, and function as a direct OE replacement. The Grey Fusion 4.0 coating has been tested to meet or exceed the ASTM-B117 salt-spray standard, exceeding original equipment corrosion resistance requirements.

Key Features:

• Full-surface Grey Fusion 4.0 coating — covers the rotor face, hat, edges, and cooling vanes for complete corrosion protection
• G3000-qualified material — OE-matched cast iron for structural integrity and maximum service life
• Lateral runout of 0.004" or less — minimizes pedal pulsation and brake noise
• Thickness variation under 0.0005" — promotes smooth, consistent braking and extended pad life
• Mill balancing — reduces vibration for quieter, more stable stopping performance
• Non-directional ground finish — ready to install straight out of the box, no bed-in machining required
• Solid rotor construction — 10.63" outside diameter, 0.551" nominal thickness

The Element3 line is the ideal solution for vehicles in rust-prone regions such as the Rust Belt and coastal areas, where uncoated rotors are particularly vulnerable to accelerated corrosion. This rotor is sold individually (1 pack).
