ARP 216-6301 Connecting Rod Bolt Kit Pro Series - ARP2000

The ARP 216-6301 is a complete connecting rod bolt kit featuring ARP2000 Pro Series fasteners designed to eliminate the weakest link in high-performance connecting rods. Engineered for superior reliability and fatigue strength, these bolts deliver exceptional clamping force at 220,000 psi, making them ideal for short track and drag racing applications as an upgrade from standard 8740 chrome moly fasteners.

Why ARP Rod Bolts Are Superior:

ARP rod bolts have been proven through rigorous testing to have ten times the fatigue strength of competing fasteners. This exceptional durability comes from ARP's proprietary manufacturing process and the use of ARP2000 alloy steel, which can be heat treated to higher levels than conventional materials while maintaining similar stress corrosion resistance characteristics to 8740 chrome moly.

Key Features:

• Forged in-house at ARP using premium quality materials for consistent performance
• 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 life
• Precision CNC-machined to exacting specifications for perfect fit
• ARP2000 alloy steel capable of 220,000 psi clamping loads
• Each bolt proudly stamped with the ARP name as assurance of quality

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts the rod and cap for optimum alignment and reduced fluctuating stress
• Provides secure interference fit (.001 to .005 range) despite wide OEM rod bolt hole tolerances
• Superior material grain flow compared to knurled bolts that create stress risers
• Virtually eliminates galling and scoring with smooth contact surfaces
• Strengthens the connecting rod itself by optimizing load distribution

Installation and Maintenance:

For maximum reliability, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005 inches. With proper installation care, stress corrosion and hydrogen embrittlement are typically not concerns with ARP2000 material. This complete kit provides everything needed for a professional connecting rod bolt upgrade.
