ARP 200-6219 Connecting Rod Bolt Kit Pro Series - ARP2000

The ARP 200-6219 is a high-performance connecting rod bolt kit featuring ARP's renowned ARP2000 alloy material. This 2-piece kit is designed as a general replacement for steel connecting rods, providing superior strength and reliability compared to OEM fasteners. ARP2000 alloy steel is heat-treated to achieve a tensile strength of 220,000 psi, making it an excellent upgrade from standard 8740 chrome moly bolts for demanding racing applications.

Why Choose ARP Connecting Rod Bolts:

ARP rod bolts are the preferred choice of connecting rod manufacturers and engine builders worldwide. Testing has demonstrated that ARP rod bolts deliver ten times the fatigue strength of competing fasteners, making them the industry standard for reliability. The connecting rod bolt is traditionally the weakest link in a connecting rod assembly, which is why serious racers and engine builders trust ARP for critical applications.

Key Features:

• 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
• ARP name proudly stamped on each bolt as assurance of quality
• Designed for optimum reliability in steel connecting rod applications

About ARP2000 Material:

ARP2000 is an advanced alloy steel capable of achieving substantially higher clamping loads than traditional 8740 chrome moly. With a safe operating tensile strength of 220,000 psi, ARP2000 is widely used in short track and drag racing as an upgrade from standard materials in both steel and aluminum connecting rods. When properly installed with appropriate lubrication, ARP2000 fasteners resist stress corrosion and hydrogen embrittlement.

Important Maintenance Note:

It is critically important to monitor bolt stretch and replace any bolt that has permanently elongated by 0.0005 inches. Regular inspection ensures continued reliability and prevents potential failure.
