ARP 300-6601 Connecting Rod Bolt Kit Super Alloy - ARP3.5 16-Piece

The ARP 300-6601 is a premium connecting rod bolt kit engineered as a direct replacement for Carrillo, Lentz, and Ferrea connecting rods. Manufactured from ARP3.5 super alloy material, this 16-piece kit delivers exceptional strength and reliability for high-performance and racing applications where extreme loads and sustained high RPM operation demand the ultimate in fastener technology.

ARP3.5 Super Alloy Material

ARP3.5 (AMS5844) represents the pinnacle of fastener materials, featuring a high-cobalt super alloy commonly found in jet engine and aerospace applications. This advanced material provides tensile strength in the 260,000-280,000 psi range with superior fatigue characteristics that far exceed conventional chrome moly or even ARP2000 fasteners. Most importantly, ARP3.5 offers complete immunity to hydrogen embrittlement and corrosion, making it ideal for Formula 1, NASCAR, IRL, and other professional racing applications where component failure is not an option.

Key Features:

• ARP3.5 super alloy construction for maximum strength and fatigue resistance
• Tensile strength rating of 260,000-280,000 psi
• Complete immunity to hydrogen embrittlement and atmospheric corrosion
• Forged in-house using premium quality materials
• Heat-treated on special vertical racks for complete 360-degree penetration
• Threads rolled after heat-treat for up to 10 times longer fatigue life
• Precision CNC-machined to exacting tolerances
• 16 pieces included (washers not included)
• Direct replacement for Carrillo, Lentz, and Ferrea connecting rods

Application Notes

This kit is designed for connecting rods in extreme high-performance applications where loads, RPM, and endurance requirements exceed the capabilities of standard materials. It is critical to monitor bolt stretch and replace any bolt that has permanently elongated by 0.0005 inches or more. Each bolt is proudly stamped with the ARP name as assurance of quality and authenticity.

Note: This listing shows "Cylinder Head Fasteners" in the product category, but this is actually a connecting rod bolt kit. Please verify the correct application before ordering.
