ARP 107-6002 High Performance Chrome Moly Connecting Rod Bolt Kit - 8740

The ARP 107-6002 is a complete connecting rod bolt kit manufactured from high-performance 8740 chrome moly steel. Designed to replace the weakest link in any connecting rod assembly, these precision-engineered fasteners deliver the strength and reliability that professional engine builders and racers demand.

Why ARP Rod Bolts Are Superior:

ARP rod bolts are the industry standard for a reason—they deliver up to 10 times the fatigue strength of competitor fasteners. Every bolt is forged in-house from premium materials and heat-treated using specialized vertical racks to ensure complete 360-degree penetration. The threads are rolled after heat treatment, a critical process that dramatically increases fatigue life and ensures consistent, reliable clamping force.

8740 Chrome Moly Material:

This kit features 8740 chrome moly steel, a quench-and-temper alloy that delivers tensile strengths between 180,000 and 210,000 psi. While considered moderate strength by today's standards, 8740 chrome moly offers excellent toughness and adequate fatigue properties for most racing applications, making it the most cost-effective choice for engines where bolt strength matches anticipated loads plus a safety margin.

Key Features:

• Forged in-house using only the finest quality 8740 chrome moly steel
• Heat-treated with special vertical racks for complete 360-degree penetration
• Threads rolled after heat-treat to provide up to 10 times longer fatigue strength
• Precision CNC-machined to exacting specifications
• Complete kit with all necessary fasteners
• Each bolt proudly stamped with the ARP name as assurance of quality

Wave-Loc Technology (if equipped):

• Wave-Loc surface contacts rod and cap for optimum alignment and stress reduction
• Provides interference fit of .001 to .005 inches for all OEM connecting rods
• Superior material grain flow compared to knurled bolts with sharp edges and stress risers
• Virtually eliminates galling and scoring of the rod through smooth contact

Important Maintenance Note:

Monitor bolt stretch carefully and replace any bolt that has permanently elongated by .0005 inches. This critical maintenance step ensures continued reliability and prevents catastrophic engine failure.

Trusted by connecting rod manufacturers worldwide as original equipment, ARP fasteners represent the pinnacle of fastener engineering. Whether you're building a street performance engine or a dedicated race motor, ARP 107-6002 rod bolts deliver the strength, consistency, and reliability your engine demands.
