ARP 234-6423 Connecting Rod Bolt Kit ARP2000 Pro Wave-Loc 2-Piece

The ARP 234-6423 is a 2-piece connecting rod bolt kit featuring ARP2000 material in the Pro Wave-Loc Series design. These precision-engineered fasteners provide superior clamping force and reliability for high-performance connecting rod applications.

ARP2000 Material Benefits:

ARP2000 alloy steel delivers exceptional strength with a clamp load capability at 220,000 psi, making it an ideal upgrade from standard 8740 chrome moly bolts. This material is widely used in short track and drag racing applications for both steel and aluminum connecting rods, offering superior fatigue resistance and reliability under extreme conditions.

Wave-Loc Technology:

• Patented Wave-Loc surface design provides optimal alignment between rod and cap, reducing fluctuating stress and strengthening the rod assembly
• Creates interference fit of .001 to .005 inches for secure installation despite OEM manufacturing tolerances
• Superior material grain flow compared to knurled designs that create stress risers
• Smooth contact surface virtually eliminates galling and scoring of connecting rod material
• Reduces bolt hole wear and extends service life

ARP Manufacturing Excellence:

• Forged in-house from premium quality ARP2000 alloy steel
• Heat-treated using specialized vertical racks for complete 360-degree heat penetration
• Threads rolled after heat-treatment to provide up to 10 times greater fatigue strength
• Precision CNC-machined to exacting specifications for consistent performance
• Each bolt proudly stamped with ARP name as assurance of quality

Installation and Maintenance:

Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches or more. With proper care during installation, ARP2000 material resists stress corrosion and hydrogen embrittlement. These fasteners represent the optimal balance of strength, reliability, and cost-effectiveness for high-performance racing applications.
