What is the tensile strength of these ARP head studs?

These ARP head studs are rated at 220,000 pounds per square inch (ksi) tensile strength. This high rating ensures they can withstand significant clamping forces required for high-performance engine builds.

What is the advantage of the 12-point nuts?

The 12-point nuts require a 12-point socket for installation. This design can offer better access and engagement in tight engine compartments compared to standard 6-point fasteners, making installation easier.

What is included in this head stud kit?

This kit includes the necessary ARP head studs, the specialized 12-point nuts, and the required washers for installation. Always consult the manufacturer's instructions for the complete list and proper installation procedure.

Product Details

This is the ARP SB2-2 head stud kit, designed for specific engine blocks. These studs are crucial for securely fastening your cylinder heads to the engine block, especially when you're looking to build a strong, reliable engine that can handle increased power or demanding use. ARP is well-known for making solid engine components, and this kit is no exception. The 7/16 inch diameter studs are made from ARP's 220ksi material, which is a strong alloy that offers excellent tensile strength to keep your heads sealed under high cylinder pressures.

What sets this kit apart is the 12-point nut design. These nuts require a 12-point socket for installation and removal, which can offer better access in tight engine bays compared to standard 6-point fasteners. The 220ksi rating means these studs can withstand significant clamping force, helping to prevent head gasket leaks and ensuring consistent performance. When you're rebuilding or modifying an engine where reliability is key, using a well-built head stud kit like this from ARP is a smart move to ensure your engine stays together.

This kit includes the studs, nuts, and washers needed for installation. Always refer to the manufacturer's installation instructions for proper torque sequences and specifications to ensure the best results for your engine build.
