Replacement Rod Bolt Kit

Rod Bolts - 7/16˝, 16-piece set

Material L19
1) Thread Size 7/16˝
2) UHL 1.725˝
3) Thread Length 0.650˝
4) Grip Length 0.300˝
5) Head Height 0.380˝
6) Socket Size 1/2 12pt, 3/16 Allen
7) Collar Dia. 0.655˝

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.

How does L19 compare to ARP2000?

L19 differs from ARP2000 in that it is a vacuum melted alloyed steel with sufficient chro
mium and carbon to achieve high hardness (but below the level of a stainless steel). L19 is air-cooled from the hardening temperature in a way that does not require an oil quench to achieve full hardness and is tempered to assure full conversion to martensite between 1025°F and 1075˚F. L19 is a proprietary material capable of achieving strengths of 220,000/230,000 or 260,000/270,000 psi as may be required. Both L19 and ARP2000 steels are modified bcc (martensite) at room temperature. L19 has the same advantage as ARP2000 in that a high strength is obtained at a high tempering temperature. This alloy is easily contaminated and requires special handling.
