Lamspeed Racing - Custom ARP L19 Main Stud Kit - Mitsubishi 4G63
Details:
Lamspeed Racing's Custom ARP L19 4G63 Main Stud Kit utilises ARP's L19 material (comparable to A1 Technologies H11 Tool Steel), 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 head studs) 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.
If you are after reliability while producing huge amounts of horsepower, this kit will meet the demands.
Specifications:
Our custom L19 main stud upgrade comes with Studs, Washers, and Bolts for a complete installation.
- Yield Strength: 200-230,000 PSI
- Tensile Strength: 260,000 PSI
Notes:
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.
