ARP 150-6005 Connecting Rod Bolt Kit Chrome Moly - 8740

The ARP 150-6005 is a high-performance connecting rod bolt kit engineered from 8740 chrome moly steel for reliable performance in demanding racing applications. This complete bolt replacement kit addresses the weakest link in any connecting rod assembly, delivering the strength and fatigue resistance needed for high-RPM engines.

Key Features:

• Forged in-house at ARP using premium quality materials for consistent performance
• Heat-treated using specialized vertical racks to ensure complete 360-degree penetration
• Threads rolled after heat-treat to provide up to 10 times longer fatigue strength compared to cut threads
• Precision CNC-machined to exacting specifications for perfect fit
• 8740 chrome moly construction offers tensile strengths between 180,000 and 210,000 psi
• Each bolt proudly stamped with the ARP name as assurance of quality

Wave-Loc Technology:

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

Important Maintenance: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 or more to maintain optimal clamping force and reliability.

ARP connecting rod bolts are the choice of leading rod manufacturers and professional racers who demand the ultimate in fatigue strength and reliability. The 8740 chrome moly material provides an excellent balance of strength, toughness, and cost-effectiveness for most racing applications.
