ARP 206-6004 Connecting Rod Bolt Kit Pro Series - ARP2000

The ARP 206-6004 is a complete connecting rod bolt kit featuring ARP2000 Pro Series material, designed to deliver superior strength and reliability for high-performance engine builds. ARP connecting rod bolts are the standard of excellence in the racing industry, with proven fatigue strength up to 10 times greater than competing fasteners. The ARP2000 alloy steel used in this kit is capable of achieving a clamp load at 220,000 psi, making it an ideal upgrade from standard 8740 chrome moly bolts for both steel and aluminum connecting rods in short track and drag racing applications.

Key Features:

• ARP2000 alloy steel construction for superior strength and durability
• Forged in-house at ARP using premium quality materials
• 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
• Precision CNC-machined to exacting specifications
• Each bolt proudly stamped with the ARP name as your assurance of quality
• Complete kit includes all necessary fasteners for the application

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts the rod and cap for optimum alignment and reduced fluctuating stress
• Provides snug interference fit (.001 to .005) despite wide range of factory tolerances
• Superior material grain flow compared to knurled bolts with sharp stress risers
• Virtually eliminates galling and scoring of the rod with smooth contact surface

ARP connecting rod bolts are chosen as original equipment by leading rod manufacturers worldwide, representing the ultimate solution for eliminating the traditional weak link in connecting rod assemblies. For optimal performance and longevity, monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inch. When properly installed and maintained, ARP 206-6004 rod bolts deliver the reliability and peace of mind demanded by serious racers and engine builders.
