ARP 204-6002 Connecting Rod Bolt Kit Pro Wave-Loc Series - ARP2000

The ARP 204-6002 is a complete connecting rod bolt kit featuring ARP2000 material with the innovative Pro Wave-Loc design. These premium fasteners are engineered to eliminate the weak link in high-performance connecting rods, delivering superior strength and reliability for demanding racing applications.

ARP2000 Material Advantage:

ARP2000 is an advanced alloy steel capable of achieving clamping loads at 220,000 psi, significantly stronger than standard 8740 chrome moly. This material is widely used in short track and drag racing as an upgrade for both steel and aluminum connecting rods, offering exceptional strength while remaining resistant to stress corrosion and hydrogen embrittlement when properly installed.

Wave-Loc Technology Benefits:

• Patented Wave-Loc surface contacts rod and cap for optimal alignment and reduced fluctuating stress
• Provides interference fit of .001 to .005 inches for OEM connecting rods, compensating for factory tolerance variations
• Superior material grain flow compared to knurled designs that create stress risers
• Eliminates galling and scoring through smooth contact surface
• Strengthens the connecting rod assembly itself by improving load distribution

ARP Manufacturing Excellence:

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

Important Maintenance Note:

Monitor bolt stretch carefully and replace any bolt that has permanently elongated by .0005 inches to maintain safety and performance.

ARP rod bolts have demonstrated ten times the fatigue strength of competitor fasteners in independent testing, making them the choice of professional engine builders and connecting rod manufacturers worldwide.
