ARP 116-6001 High Performance Connecting Rod Bolt Kit Chrome Moly - 8740

The ARP 116-6001 is a complete connecting rod bolt kit featuring high-performance 8740 chrome moly construction. Trusted by connecting rod manufacturers worldwide as original equipment, ARP rod bolts are engineered to eliminate the traditional weak link in connecting rod assemblies through superior material quality and precision manufacturing processes.

Key Features:

• Forged in-house at ARP using premium quality 8740 chrome moly steel
• Heat-treated using specialized vertical racks ensuring complete 360-degree penetration
• Threads rolled after heat treatment for up to 10 times longer fatigue life
• Precision CNC-machined to exacting specifications for optimal reliability
• Delivers tensile strength between 180,000 and 210,000 psi

Wave-Loc Technology:

• Wave-Loc surface contacts rod and cap for optimum alignment and stress reduction
• Provides secure interference fit (.001 to .005 range) accommodating wide OEM rod bolt hole tolerances
• Superior material grain flow compared to knurled bolts with stress-inducing sharp edges
• Eliminates galling and scoring through smooth contact surfaces
• Strengthens the connecting rod itself by reducing fluctuating stress

The 8740 chrome moly material offers excellent toughness and adequate fatigue properties for most racing applications. As a quench and temper steel, it provides a cost-effective solution when bolt strength appropriately matches anticipated loads with proper safety margins. ARP's proprietary rolling of threads after heat treatment delivers superior fatigue strength compared to competitive fasteners.

Important: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inch. Each bolt features the ARP name stamped as assurance of quality and authenticity.
