ARP SBC Dart LS Next 15-Bolt Head Stud Kit

If you're building a high-performance 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 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 head studs are no exception.

These studs are made from ARP's proprietary 8740 chromoly steel, heat-treated to a tensile strength of 200,000 psi. This material choice means they are strong and durable enough to withstand the significant clamping forces required in performance builds. The kit includes the necessary studs, nuts, and washers, all manufactured to ARP's tight tolerances. Using head studs instead of bolts generally offers more consistent clamping force, which is critical for preventing head gasket leaks in boosted or high-compression engines.

When installing these studs, it's important to follow ARP's recommended procedure for cleaning the block and head bolt holes, as well as using their thread sealant and torque-down method. This ensures you achieve the correct clamping force and a reliable seal for your engine build.
