ARP 154-6001 Connecting Rod Bolt Kit Chrome Moly - 8740

The ARP 154-6001 is a high-performance connecting rod bolt kit manufactured from premium 8740 chrome moly steel. Designed to eliminate the weakest link in any connecting rod assembly, this complete bolt kit delivers the reliability and strength that professional engine builders and racers demand.

Why ARP Rod Bolts Are Superior:

ARP rod bolts are engineered to deliver up to ten times the fatigue strength of competing fasteners. This exceptional durability comes from ARP's proprietary manufacturing process and quality control standards. Each bolt is proudly stamped with the ARP name as assurance of quality and performance.

8740 Chrome Moly Material:

The 8740 chrome moly alloy offers excellent toughness with adequate fatigue properties for most racing applications. This quench and temper steel delivers tensile strengths between 180,000 and 210,000 psi, providing a cost-effective solution for engines where bolt strength requirements align with anticipated loads plus a reasonable safety margin.

Manufacturing Excellence:

• Forged in-house at ARP using only the finest quality materials
• Heat-treated using special vertical racks to assure complete 360-degree penetration
• Threads rolled after heat-treat to provide up to 10 times longer fatigue strength
• Precision CNC-machined to exacting specifications
• Specially designed for optimum reliability in each application

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress
• Provides snug interference fit of .001 to .005 inch for all OEM connecting rods, despite wide factory tolerances
• Superior material grain flow compared to knurled bolts that have sharp edges and built-in stress risers
• Virtually eliminates galling and scoring of the rod through smooth contact with no digging
• Strengthens the rod itself by improving load distribution

Important Maintenance Note:

Monitor the stretch of each bolt regularly and replace when permanent elongation reaches .0005 inch to maintain optimal performance and safety.
