The ARP 114-6001 is a high-performance connecting rod bolt kit manufactured from 8740 chrome moly steel. Designed to eliminate the weak link in connecting rod assemblies, these fasteners deliver the superior strength and reliability that professional engine builders and racers demand. Each bolt is precision-engineered to withstand extreme loads and high RPM operation while providing consistent, repeatable clamping force.

Key Features:

• Forged in-house from premium 8740 chrome moly steel for reliable tensile strength between 180,000-210,000 psi
• Threads rolled after heat-treatment to provide up to 10 times longer fatigue life compared to competitive fasteners
• Heat-treated using specialized vertical racks ensuring complete 360-degree penetration for uniform strength
• Precision CNC-machined to exacting specifications for optimal fit and performance
• Complete bolt kit with everything needed for installation
• Each bolt proudly stamped with the ARP name as assurance of quality

Available Wave-Loc Technology:

• Wave-Loc surface design contacts rod and cap for optimal alignment and reduced fluctuating stress
• Provides interference fit of .001 to .005 inches accommodating wide range of OEM rod bolt hole tolerances
• Superior material grain flow compared to knurled bolts that create stress risers
• Virtually eliminates galling and scoring with smooth contact surface
• Strengthens the connecting rod itself by improving load distribution

About 8740 Chrome Moly Material:

8740 chrome moly is a proven quench and temper steel offering excellent toughness and adequate fatigue properties for most racing applications. While considered moderate strength by modern standards, it remains a cost-effective choice that delivers reliable performance when properly manufactured with post-heat-treat thread rolling—the standard ARP production practice.

Installation Note: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches to maintain optimal connecting rod integrity and prevent failure.
