ARP 234-6403 Connecting Rod Bolt Kit Pro Wave-Loc Series - ARP2000

The ARP 234-6403 is a complete connecting rod bolt kit featuring ARP2000 alloy steel with the innovative Wave-Loc design. This professional-grade fastener kit delivers superior clamping force and reliability for high-performance engine builds, with ARP2000 material capable of achieving clamp loads at 220,000 psi.

Wave-Loc Technology Benefits:

• Precision-machined wave surface contacts rod and cap for optimal alignment and reduced stress
• Provides interference fit of .001 to .005 inches to accommodate factory tolerance variations
• Superior material grain flow compared to knurled designs eliminates stress risers
• Smooth contact surface prevents galling and scoring of connecting rod bores
• Strengthens the connecting rod itself by reducing fluctuating stress

ARP2000 Material Specifications:

• Heat-treated alloy steel with 220,000 psi tensile capability
• Ten times the fatigue strength of conventional rod bolts
• Forged in-house using premium quality materials
• Threads rolled after heat treatment for maximum fatigue resistance
• Vertical rack heat-treating ensures complete 360-degree penetration

Manufacturing Excellence:

• Precision CNC-machined to exacting specifications
• ARP name stamped on each bolt as quality assurance
• Specifically engineered for optimum reliability in demanding applications
• Resistant to stress corrosion and hydrogen embrittlement with proper installation

This complete kit is ideal for short track and drag racing applications requiring an upgrade from standard chrome moly fasteners. The ARP2000 alloy provides the perfect balance of strength, fatigue resistance, and cost-effectiveness for both steel and aluminum connecting rods. Regular inspection is recommended—replace bolts when permanent elongation exceeds .0005 inches.
