ARP 150-6424 Wave-Loc Connecting Rod Bolt Kit Chrome Moly - 8740

The ARP 150-6424 is a high-performance connecting rod bolt kit featuring Wave-Loc technology and premium 8740 chrome moly construction. This 2-piece fastener set delivers the superior strength and fatigue resistance that ARP is known for throughout the racing industry.

Why ARP Rod Bolts Are Superior:

The connecting rod bolt has traditionally been the weak link in any connecting rod assembly. ARP rod bolts have been proven through rigorous testing to have ten times the fatigue strength of competitor fasteners. This exceptional durability comes from ARP's specialized manufacturing process and commitment to quality materials. It's critically important to monitor bolt stretch and replace any bolt that has permanently elongated by .0005 inches.

8740 Chrome Moly Material:

These bolts are manufactured from 8740 chrome moly steel, a quench and temper alloy offering excellent toughness with adequate fatigue properties for most racing applications. This material delivers tensile strengths between 180,000 and 210,000 psi when properly heat-treated. Chrome moly provides a cost-effective solution with reliable performance and an appropriate safety margin for typical racing loads.

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress
• Provides snug interference fit (.001 to .005 range) for all OEM connecting rods despite wide factory tolerances
• Superior material grain flow compared to knurled bolts that have sharp edges and stress risers
• Virtually eliminates galling and scoring through smooth contact surface
• Strengthens the connecting rod itself by improving load distribution

ARP Manufacturing Process:

• Forged in-house 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
• Each bolt proudly stamped with the ARP name as assurance of quality

This kit includes 2 pieces and is designed for aftermarket connecting rod applications requiring reliable, high-performance fasteners. ARP rod bolts are chosen as original equipment by numerous connecting rod manufacturers who proudly advertise their products as being equipped with ARP fasteners.
