ARP 254-6402 Connecting Rod Bolt Kit Pro Wave-Loc Series - ARP2000

The ARP 254-6402 is a complete connecting rod bolt kit featuring ARP2000 material with the innovative Pro Wave-Loc design. These precision-engineered fasteners deliver superior clamping force and fatigue life, making them the preferred choice for high-performance and racing applications where connecting rod reliability is critical.

ARP2000 Material Advantage:

ARP2000 alloy steel provides a significant upgrade over standard 8740 chrome moly, capable of achieving clamping loads at 220,000 psi. This advanced material is widely used in short track and drag racing for both steel and aluminum connecting rods, offering exceptional strength and resistance to stress corrosion when properly installed.

Wave-Loc Technology:

• Patented Wave-Loc surface design ensures optimal alignment between rod and cap, reducing fluctuating stress and strengthening the rod assembly
• Provides interference fit of .001 to .005 inches, accommodating wide OEM rod bolt hole tolerances
• Superior material grain flow compared to knurled bolts, eliminating sharp edges and stress risers
• Smooth contact surface virtually eliminates galling and scoring of connecting rod bores
• Snug, secure fit for all OEM connecting rods without damaging interference

ARP Manufacturing Excellence:

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

Superior Fatigue Strength:

Independent testing has demonstrated that ARP rod bolts deliver ten times the fatigue strength of competing fasteners. This exceptional durability makes ARP the preferred original equipment choice for leading connecting rod manufacturers worldwide.

Installation Note: Always monitor bolt stretch during use and replace any bolt that has permanently elongated by .0005 inches to maintain optimal clamping force and reliability.
