ARP 124-6001 Connecting Rod Bolt Kit Chrome Moly - 8740

The ARP 124-6001 is a high-performance connecting rod bolt kit manufactured from 8740 chrome moly steel. Designed to eliminate the traditional weak link in connecting rods, these precision-engineered fasteners deliver the reliability and strength that professional racers demand. ARP rod bolts are trusted by connecting rod manufacturers worldwide as original equipment, providing superior fatigue resistance and durability in high-stress racing environments.

Key Features:

• Forged in-house using premium 8740 chrome moly steel with tensile strength of 180,000-210,000 psi
• Threads rolled after heat treatment to provide up to 10 times longer fatigue life compared to competitors
• Heat-treated using specialized vertical racks for complete 360-degree penetration and consistent material properties
• Precision CNC-machined to exacting tolerances for optimal performance
• Complete kit with all necessary fasteners for connecting rod assembly
• ARP name proudly stamped on each bolt as assurance of quality

Wave-Loc Technology:

• Patented Wave-Loc surface design provides optimal alignment between rod and cap while reducing fluctuating stress
• Creates secure interference fit (.001 to .005 range) for all OEM connecting rods despite manufacturing tolerances
• Superior material grain flow compared to knurled designs that create stress risers
• Eliminates galling and scoring with smooth contact surface

Installation and Maintenance:

Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches or more. The 8740 chrome moly material offers excellent fatigue properties for most racing applications when properly maintained. As a quench and temper steel, this material provides adequate strength with good toughness characteristics, making it a cost-effective solution for engines operating within normal load parameters.

ARP's manufacturing process ensures superior quality through controlled forging, precise heat treatment, and post-heat-treat thread rolling. This production methodology delivers fasteners with exceptional consistency and reliability, giving racers confidence in their engine's most critical connection points.
