ARP L19 12 Head Stud Kit, LS1 thru 2003

[FSTR-THANU]

USED

ARP's L19 material (comparable to A1 Technologies H11 Tool Steel) is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared with 8740 (standard ARP headstuds) and is capable of delivering a clamp load at 260,000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000.

Yield Strength: 200-230,000 PSI
Tensile Strength: 260,000 PSI

This kit includes exactly what you see.

Are they 1/2"
Any idea how many times they were torqued?

[FSTR-THANU]

Nope. No need for 1/2" when using l19.
