L19 Head Studs Evo 8/9 DSM

ARP's L19 material is a premium steel that is processed to deliver superior strength and fatigue properties comparable to A1 Technologies H11 Tool Steel. 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. These come packaged individually wrapped in a special wax paper to prevent contact with moisture until ready to be used. 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. 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

Great studs and worth the upgrade

These head studs are the best option if you're going to install any kind of studs on your 4g63 motor. The quality of these studs are amazing and hold very good. I'm glad my evo 9 motor has these installed on them and they have not cause me any problems at all. The guys at MAP even wrote on the package, the proper torque I should torque it to as well! Very helpful and very easy to installed.
