ARP 200-6208 Connecting Rod Bolt Kit Pro Series - ARP2000 8-Piece

The ARP 200-6208 is an 8-piece connecting rod bolt kit manufactured from ARP2000 alloy steel, designed as a general replacement for steel connecting rods. This Pro Series kit delivers superior strength and reliability compared to OEM fasteners, with ARP2000 material capable of achieving a clamp load at 220,000 psi tensile strength.

Key Features:

• Forged in-house at ARP using premium quality ARP2000 alloy steel
• Heat-treated using special vertical racks to ensure complete 360-degree penetration
• Threads rolled after heat-treat to provide up to 10-times longer fatigue strength than competitive bolts
• Precision CNC-machined to exacting specifications for consistent performance
• ARP name stamped on each bolt as assurance of quality

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress
• Provides interference fit of .001 to .005 inches for all OEM connecting rods despite varying factory tolerances
• Superior material grain flow compared to knurled bolts that create stress risers
• Eliminates galling and scoring of the rod with smooth contact surface

About ARP2000 Material:

ARP2000 is an alloy steel heat-treated to a higher level than traditional 8740 chrome moly, producing greater strength while maintaining excellent fatigue properties. This material is widely used in short track and drag racing applications as an upgrade from chrome moly in both steel and aluminum rods. With proper installation care, stress corrosion and hydrogen embrittlement are typically not concerns.

Important: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches or more to ensure continued reliability and safety.
