ARP 104-6023 Connecting Rod Bolt Kit Cap Screw - ARP2000 2-Piece

The ARP 104-6023 is a high-performance connecting rod bolt kit featuring ARP's Pro Series ARP2000 alloy steel in a cap screw design. This 2-piece kit delivers superior strength and fatigue resistance compared to standard connecting rod bolts, making it an ideal upgrade for performance and racing applications.

ARP2000 Material Advantages:

ARP2000 is an advanced alloy steel heat-treated to achieve a clamp load rating of 220,000 psi, offering significantly greater strength than traditional 8740 chrome moly bolts. This material is widely used in short track and drag racing applications as a reliable upgrade for both steel and aluminum connecting rods. ARP2000 provides excellent resistance to stress corrosion and hydrogen embrittlement when properly installed.

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 strength
• Precision CNC-machined to exacting specifications for perfect fitment
• Cap screw design for reliable clamping force
• Each bolt proudly stamped with the ARP name as assurance of quality

Why Choose ARP Rod Bolts:

ARP rod bolts are the preferred choice of connecting rod manufacturers and racers worldwide. Testing has demonstrated that ARP rod bolts deliver up to ten times the fatigue strength of competing fasteners. The connecting rod bolt has historically been the weak link in engine reliability, and ARP's advanced manufacturing processes—including post-heat-treat thread rolling and precision machining—ensure maximum durability under extreme loads and high RPM conditions.

Important: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by 0.0005 inches or more to maintain optimal safety and performance.
