ARP 153-6002 Connecting Rod Bolt Kit High Performance Chrome Moly - 8740

The ARP 153-6002 is a complete connecting rod bolt kit featuring high-performance 8740 chrome moly construction. Designed to eliminate the traditional weak link in connecting rods, these precision-engineered fasteners deliver the reliability and strength that professional racers and engine builders demand.

Key Features:

• Forged in-house at ARP using premium quality materials for consistent performance
• Heat-treated using special vertical racks to ensure complete 360-degree penetration
• Threads rolled after heat-treat to provide up to 10 times longer fatigue strength
• Precision CNC-machined to exacting specifications for perfect fitment
• 8740 chrome moly steel delivers tensile strengths between 180,000 and 210,000 psi

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts the rod and cap for optimum alignment and stress reduction
• Provides snug interference fit (.001 to .005 range) for all OEM connecting rods despite varying factory tolerances
• Superior material grain flow compared to knurled bolts that create stress risers
• Smooth contact surface virtually eliminates galling and scoring of the rod
• Strengthens the connecting rod itself by reducing fluctuating stress

Installation and Maintenance:

It is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005 inch. This maintenance practice ensures continued reliability and safety in high-performance applications.

ARP's 8740 chrome moly material offers a cost-effective solution with adequate fatigue properties for most racing applications. The combination of quality materials, proprietary manufacturing processes, and post-heat-treat thread rolling results in connecting rod bolts with superior fatigue strength compared to competing products. Each bolt is proudly stamped with the ARP name as your assurance of quality and performance.
