ARP 206-6002 High Performance Chrome Moly Connecting Rod Bolt Kit - 8740

The ARP 206-6002 is a complete connecting rod bolt kit manufactured from high-performance 8740 chrome moly steel. Trusted by leading connecting rod manufacturers as original equipment, ARP rod bolts are engineered to eliminate the traditional weak link in high-performance connecting rods through superior materials and precision manufacturing processes.

Key Features:

• Forged in-house at ARP facilities using premium quality 8740 chrome moly steel
• Heat-treated on special vertical racks to ensure complete 360-degree penetration for consistent strength
• Threads rolled after heat treatment to provide up to 10 times longer fatigue life compared to cut threads
• Precision CNC-machined to exacting specifications for optimal reliability
• Each bolt proudly stamped with the ARP name as assurance of quality

Wave-Loc Technology Benefits:

• Wave-Loc surface design contacts the rod and cap for optimum alignment and reduced fluctuating stress
• Provides secure interference fit (.001 to .005 range) accommodating wide factory rod bolt hole tolerances
• Superior material grain flow compared to knurled bolts that create stress risers
• Virtually eliminates galling and scoring of the connecting rod through smooth surface contact

8740 Chrome Moly Material:

8740 chrome moly is a tough, quench-and-temper steel with excellent fatigue properties for most racing applications. Heat-treated to deliver tensile strengths between 180,000 and 210,000 psi, this proven material offers the ideal balance of strength, reliability, and cost-effectiveness for performance engines.

Installation Note: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inch to maintain optimal clamping force and prevent failure.
