The ARP 154-6004 cylinder head fastener kit delivers the superior clamping force and reliability that engine builders demand for high-performance applications. Manufactured from premium 8740 chrome moly steel, these fasteners are engineered to withstand extreme cylinder pressures and thermal cycling while maintaining consistent torque values over repeated heat cycles.

Key Features:

• Constructed from high-strength 8740 chrome moly steel with tensile strength up to 200,000 psi
• Forged in-house at ARP facilities using aerospace-quality materials and strict quality control
• Heat-treated on specialized vertical racks ensuring complete 360-degree penetration for uniform hardness
• Threads rolled after heat treatment to provide up to 10 times greater fatigue strength compared to cut threads
• Precision CNC-machined to exacting tolerances for consistent clamping loads
• Application-specific design optimized for cylinder head retention and gasket sealing
• Each fastener proudly stamped with the ARP name as assurance of quality

Why ARP Fasteners:

ARP fasteners are the industry standard for high-performance and racing engines because they eliminate the weak link in engine assembly. Superior materials, proprietary heat treatment processes, and post-heat-treat thread rolling combine to create fasteners with exceptional fatigue resistance. Whether you're building a street performance engine or a full competition powerplant, ARP fasteners provide the reliability and consistency needed to keep your cylinder heads secure under extreme conditions.

Complete kit includes all necessary fasteners, washers, and ARP Ultra-Torque assembly lubricant for proper installation. Always follow manufacturer torque specifications and use ARP assembly lube for optimal clamping force and fastener life.
