Raybestos 66565FZN Element3 RPT Coated Disc Brake Rotor with Integrated Parking Brake

The Raybestos 66565FZN is a Element3 Rust Prevention Technology (RPT) coated disc brake rotor featuring an integrated drum-in-hat (DIH) parking brake design. Engineered as a direct OE replacement, this rotor is built for drivers who demand long-lasting corrosion protection and consistent stopping performance — especially in rust-prone climates.

Grey Fusion 4.0 Full-Surface Coating:

• Entire rotor surface is coated — including the cooling vanes — with a proprietary Grey Fusion 4.0 coating that resists corrosion and significantly delays rust-induced performance degradation
• Subjected to 300+ hours of salt spray testing to validate durability in harsh environments
• Ideal for vehicles driven in rust belt regions, coastal areas, and cold-weather climates where road salt and moisture accelerate rotor corrosion

OE-Matched Engineering:

• Developed from OE samples and manufactured with G3000-qualified gray iron to guarantee proper form, fit, and function
• Lateral runout of 0.0004" or less and thickness variation of less than 0.0005" for smooth, vibration-free braking
• Mill balanced and 100% validated to minimize thickness variation and rotor-induced pedal pulsation
• Integrated drum-in-hat (DIH) parking brake design for vehicles with rear disc brakes and a separate mechanical parking brake

Key Features:

• Proprietary RPT (Rust Prevention Technology) full-surface coating
• Grey Fusion 4.0 coating on all surfaces including internal cooling vanes
• G3000 gray iron construction
• Drum-in-hat integrated parking brake
• Sold as a single (1 pack) rotor
• Meets or exceeds OE specifications
