ARP 145-6402 High Performance Wave-Loc Connecting Rod Bolt Kit

The ARP 145-6402 is a complete high-performance connecting rod bolt kit featuring Wave-Loc technology and constructed from 8740 chrome moly steel. Designed to address the traditional weak link in connecting rods, these fasteners deliver superior reliability and fatigue strength for demanding racing applications.

Key Features:

• 8740 chrome moly construction with tensile strength of 180,000-210,000 psi
• Wave-Loc design provides interference fit (.001 to .005) for optimal rod and cap alignment
• Threads rolled after heat treatment for up to 10 times longer fatigue life
• Forged in-house using precision vertical rack heat-treating for complete 360-degree penetration
• CNC-machined to exacting specifications with ARP quality stamp on each bolt
• Smooth Wave-Loc surface eliminates galling and scoring while improving material grain flow
• Reduces fluctuating stress to strengthen the connecting rod itself

Material Properties:

The 8740 chrome moly material is a quench and temper steel that provides excellent toughness and adequate fatigue properties for most racing applications. When properly maintained, these bolts offer reliable performance in high-stress environments.

Installation Note: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches. Keep bolts well-oiled and protected from moisture for optimal service life.
