ARP 234-6402 Pro Wave-Loc Connecting Rod Bolt Kit - ARP2000

The ARP 234-6402 is a complete connecting rod bolt kit featuring ARP2000 alloy steel fasteners with the patented Wave-Loc design. ARP2000 is an advanced alloy steel capable of achieving a clamp load at 220,000 psi, offering superior strength compared to standard 8740 chrome moly while maintaining excellent fatigue resistance. This makes it an ideal upgrade for short track and drag racing applications in both steel and aluminum connecting rods.

Wave-Loc Technology Benefits:

• Patented Wave-Loc surface contacts the rod and cap for optimal alignment and reduced fluctuating stress
• Provides secure interference fit (.001 to .005 range) for all OEM connecting rods despite factory tolerance variations
• Superior material grain flow compared to knurled bolts that create stress risers
• Eliminates galling and scoring with smooth contact surface
• Strengthens the connecting rod itself by reducing stress concentrations

ARP Manufacturing Excellence:

• Forged in-house using premium quality materials
• Heat-treated with special vertical racks ensuring complete 360-degree penetration
• Threads rolled after heat-treat providing up to 10 times longer fatigue life
• Precision CNC-machined to exacting specifications
• ARP name stamped on each bolt as assurance of quality

About ARP2000 Material: ARP2000 alloy steel can be safely heat treated to higher levels than 8740 chrome moly, producing greater strength while sharing similar handling characteristics. With proper installation procedures, stress corrosion and hydrogen embrittlement are typically not concerns. This material is widely trusted in demanding racing environments where reliability and consistent clamping force are critical.

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