ARP 230-6301 Connecting Rod Bolt Kit

ARP connecting rod bolts are the industry standard for high-performance and racing engines, chosen by leading connecting rod manufacturers as original equipment. The ARP 230-6301 connecting rod bolt kit provides the strength and reliability needed to handle extreme loads and high RPM conditions while eliminating the traditional weak point in connecting rod assemblies.

Key Features:

• Forged in-house using premium quality materials for consistent strength
• Heat-treated using vertical racks to ensure complete 360-degree penetration
• Threads rolled after heat-treat for up to 10 times longer fatigue life compared to competitor fasteners
• Precision CNC-machined to exacting specifications for perfect fit
• Application-specific design optimized for maximum reliability

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts rod and cap for improved alignment and reduced fluctuating stress
• Interference fit range of .001 to .005 accommodates wide OEM rod bolt hole tolerances
• Superior grain flow compared to knurled bolts that create stress risers
• Eliminates galling and scoring through smooth contact surface
• Strengthens the connecting rod itself by optimizing load distribution

Material Options: ARP rod bolts are available in multiple material grades including 8740 Chrome Moly (180,000-210,000 psi), ARP2000 (220,000 psi), L19 (260,000 psi), Aermet (290,000-310,000 psi), Inconel 718 (210,000-230,000 psi), and Custom Age 625+ (260,000-280,000 psi). Material selection should be based on application loads, RPM range, and required safety margin.

Important: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inch. Each bolt is stamped with the ARP name as assurance of quality and authenticity.
