About L19 Steel:

L19 is a premium processed steel that delivers superior strength and fatigue properties compared to standard 8740 chrome moly and ARP2000 materials. This very high strength material is capable of handling extreme inertia loads, making it ideal for short track and drag racing applications where connecting rod bolt reliability is critical. Important: L19 steel requires proper care during installation and must be kept well-oiled and protected from moisture to prevent stress corrosion.

Application Notes:

This bolt kit is specifically designed as a Carrillo connecting rod replacement. It's critically important to monitor bolt stretch during use and replace bolts when they have permanently elongated by 0.0005 inches. Regular inspection ensures maximum reliability and safety in high-performance applications.

ARP connecting rod bolts have been proven through extensive testing to provide ten times the fatigue strength of competitor fasteners, making them the trusted choice for professional racers and engine builders worldwide.
