Hey Everyone,

After 6-8 long weeks of waiting for these bad boy studs, they are finally here. We will try our best to keep them on the shelf at all times as well.

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. 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.

Because of the many head lifting issues on 4G63 blocks running in excess of 35+ PSI, a stronger stud needed to be manufactured to meet the demands of today's top engine builders and racers alike. Typical lead time on these studs is 6-8 weeks, but we have ordered these in advance and will be shelf stocking them! The L19 head stud upgrade comes with Studs, Washers, and Bolts for a complete installation. No Modification to your cylinder head or block is required as these are a direct drop-in replacement for the OEM head stud!

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

*Note: The nuts and washers included in this kit still utilize premium grade 8740 alloy as only the stud is subjected increased pressure. ARP Moly Assembly Lubricant also included in kit.

ARP "L19" Headstud Kit: Mitsubishi Eclipse 6-Bolt = $289.95

ARP "L19" Headstud Kit: Mitsubishi Eclipse 7-Bolt = $235.50

Thanks,
Hung

Hey Cory, thanks for the kind words

These studs truely are awesome, especially being a direct bolt-on affair. Previously, racers looking for more stud holding strength meant either going with the more expensive A1 studs or getting custom ARP 1/2" L19 studs. This was very inconvenient due to the long wait time for the A1s and the custom machine work required to utilize the larger ARP 1/2" studs. Now we've pre-ordered these 8 weeks in advance so you don't have to!
