ARP 200-6201 Connecting Rod Bolt Kit for Manley Rods - ARP2000

The ARP 200-6201 is a high-performance connecting rod bolt kit engineered as a direct replacement for Manley connecting rods using part numbers 14051 and 14055. This 16-piece kit includes precision-manufactured bolts with washers, constructed from ARP2000 Pro Series material for superior strength and reliability in high-performance and racing applications.

ARP2000 Material Advantage:

ARP2000 is an advanced alloy steel heat-treated to achieve a clamping load at 220,000 psi, offering significantly greater strength than standard 8740 chrome moly fasteners. This material is widely used in short track and drag racing as an upgrade for both steel and aluminum connecting rods, providing exceptional fatigue resistance while maintaining resistance to stress corrosion and hydrogen embrittlement when properly installed.

Key Features:

• Forged in-house at ARP using premium quality materials
• Heat-treated using specialized vertical racks for complete 360-degree penetration
• Threads rolled after heat-treat to provide up to 10 times longer fatigue strength
• Precision CNC-machined to exacting specifications
• Direct replacement for Manley rod bolt part numbers 14051 and 14055
• Includes washers for proper installation
• Each bolt proudly stamped with ARP name for quality assurance

Wave-Loc Technology (if applicable):

Select ARP rod bolts feature the patented Wave-Loc surface design that contacts the rod and cap for optimum alignment and reduction of fluctuating stress. This innovative design provides an interference fit of .001 to .005 inches, accommodating OEM connecting rod tolerances while eliminating galling and scoring. The Wave-Loc surface delivers superior material grain flow compared to knurled bolts, without sharp edges or built-in stress risers.

Critical Maintenance Note:

It is essential to monitor bolt stretch and replace any bolt that has permanently elongated by .0005 inches or more. Regular inspection ensures continued reliability and optimal performance in demanding racing environments.

ARP connecting rod bolts are the choice of professional engine builders and racers worldwide, offering proven reliability, superior fatigue strength, and the performance needed for high-RPM, high-stress applications.
