ARP SBC Dart LS Next 15-bolt 1/2in head stud kit

If you're building a high-performance small-block Chevy engine using a Dart LS Next block with a 15-bolt pattern, you need head studs that can handle the increased cylinder pressures. This ARP head stud kit is designed specifically for that application, ensuring your cylinder heads stay securely seated under demanding conditions. ARP has a solid reputation for making well-built engine components, and these studs are no exception.

These studs are made from ARP's proprietary 8740 chromoly steel, which is heat-treated to a tensile strength of 200,000 psi. This material choice means they are strong enough to withstand the significant clamping forces required for high-horsepower builds. The 1/2-inch diameter studs provide a substantial grip, and the kit includes the necessary nuts and washers, all made to ARP's exacting standards. Using studs instead of bolts makes future cylinder head removal and installation much easier, as you don't have to worry about stretching the fasteners.

When installing these studs, it's important to follow ARP's recommended torque-to-yield procedure and use their assembly lubricant. This ensures the studs stretch properly to achieve the correct clamping force without being overstressed. This kit is a well-built option for anyone serious about building a reliable and powerful LS Next engine.
