ARP rod bolts are the industry standard, chosen by leading connecting rod manufacturers as original equipment due to their exceptional reliability and proven performance in demanding racing applications.

Key Features:

• Constructed from 8740 chrome moly steel with tensile strength between 180,000-210,000 psi
• Forged in-house using premium quality materials for consistent performance
• Heat-treated on vertical racks to ensure complete 360-degree penetration
• Threads rolled after heat treatment for up to 10 times longer fatigue life
• Precision CNC-machined to exacting tolerances
• Each bolt proudly stamped with ARP name as assurance of quality

Wave-Loc Design Benefits:

• Wave-Loc surface contacts rod and cap for optimal alignment and reduced fluctuating stress
• Provides secure interference fit (.001 to .005 range) for all OEM connecting rods
• Superior material grain flow compared to knurled bolts that create stress risers
• Smooth contact surface virtually eliminates galling and scoring of the rod
• Accommodates wide range of factory rod bolt hole tolerances

ARP rod bolts have been proven through testing to deliver ten times the fatigue strength of competing fasteners, making them the preferred choice for racers who demand maximum reliability. The 8740 chrome moly material offers excellent toughness and adequate fatigue properties for most racing applications, providing an optimal balance of performance and cost-effectiveness.

Important: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inch to maintain peak performance and safety.
