The L19 rod bolts are manufactured with a premium steel that is processed to deliver superior strength and fatigue properties. The L19 bolts are very high strength material compared to 8740 and ARP2000 and are capable of delivering a clamp load at 260,000 psi. It is primarily used in short track and drag racing applications where extremely high cylinder pressure inertia loads exceed the clamping capability of ARP2000 and 8740. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.
