ARP 245-6402 Cylinder Head Fasteners for Ford Applications

The ARP 245-6402 cylinder head fastener kit provides premium fastening solutions engineered for high-performance Ford engine builds. These precision-manufactured fasteners deliver superior clamping force and reliability compared to OEM hardware, making them essential for engines running increased boost, higher compression ratios, or elevated RPM.

Key Features:

• Manufactured from ARP2000 alloy steel for exceptional strength and fatigue resistance
• Heat-treated to achieve 220,000 psi tensile strength for maximum clamping load
• Threads rolled after heat treatment to provide up to 10 times longer fatigue life
• Precision CNC-machined to exacting tolerances for consistent torque values
• Black oxide finish for corrosion resistance and professional appearance
• Complete kit includes all necessary fasteners, washers, and assembly lubricant

ARP2000 Material Advantages:

ARP2000 is a premium alloy steel capable of safely achieving higher heat treatment levels than standard chrome moly materials. This results in superior clamping loads at 220,000 psi, making it ideal for both steel and aluminum cylinder head applications in street performance, drag racing, and short track environments. When properly installed with the included ARP Ultra-Torque lubricant, these fasteners provide consistent and reliable clamping force.

Installation Note:

Always follow ARP's torque specifications and use the provided assembly lubricant for accurate torque readings and optimal performance. Fasteners should be inspected regularly in racing applications and replaced if any permanent elongation is detected.
