ARP 200-6228 Connecting Rod Bolt Kit Pro Series - ARP2000 2-Piece

The ARP 200-6228 Connecting Rod Bolt Kit delivers professional-grade reliability for steel connecting rods using ARP's proven ARP2000 alloy material. This 2-piece bolt set is engineered to eliminate the weakest link in high-performance connecting rods, providing superior clamping force and fatigue resistance critical for demanding racing applications.

ARP2000 Material Advantage:

ARP2000 alloy steel is heat-treated to achieve a clamp load rating of 220,000 psi, offering significantly higher strength than standard 8740 chrome moly fasteners. This advanced material is widely trusted in short track and drag racing environments where connecting rod bolt failure is not an option. ARP2000 provides excellent resistance to stress corrosion and hydrogen embrittlement when properly installed and maintained.

Superior Manufacturing Process:

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

Maintenance and Installation:

It is critically important to monitor bolt stretch during service and replace any bolt that has permanently elongated by 0.0005 inch or more. Proper installation procedures and use of ARP Ultra-Torque assembly lubricant will ensure optimal performance and longevity. Testing has demonstrated that ARP rod bolts deliver ten times the fatigue strength of competing fasteners, making them the preferred choice of connecting rod manufacturers worldwide.

Many aftermarket connecting rod manufacturers choose ARP bolts as original equipment, advertising this partnership as a mark of quality and reliability. Whether you're building a street performance engine or a full competition powerplant, ARP 200-6228 rod bolts provide the strength and durability required for maximum engine reliability.
