ARP 200-6003 Connecting Rod Bolt Kit High Performance 8740 Chrome Moly 16 Pieces

The ARP 200-6003 is a high-performance connecting rod bolt kit designed as a direct replacement for Manley and Elgin connecting rods. This 16-piece kit includes precision-engineered bolts and washers, manufactured from ARP's proven 8740 chrome moly alloy for superior strength and reliability in demanding racing applications.

Key Features:

• Forged in-house at ARP using premium quality 8740 chrome moly steel
• Heat-treated using special vertical racks to ensure complete 360-degree penetration
• Threads rolled after heat-treatment to provide up to 10 times longer fatigue strength
• Precision CNC-machined to exacting tolerances for consistent performance
• Includes washers for complete installation
• Each bolt proudly stamped with the ARP name as assurance of quality

Material Specifications:

The 8740 chrome moly material is a quench and temper steel heat-treated to deliver tensile strengths between 180,000 and 210,000 psi. This proven alloy offers excellent toughness and adequate fatigue properties for most racing applications, making it a cost-effective solution that balances strength with reliability.

Important Installation Notes:

It is critically important to monitor the stretch of each bolt during use. Bolts should be replaced when they have permanently elongated by 0.0005 inch to maintain optimal connecting rod integrity and prevent failure.

ARP connecting rod bolts are the choice of professional racers and leading connecting rod manufacturers worldwide, offering superior fatigue strength—testing has demonstrated up to 10 times the fatigue life compared to competing fasteners.
