ARP SB2-2 3/8in block 220ksi 12pt head stud kit

The 3/8 inch diameter studs in this ARP SB2-2 kit are forged from ARP's proprietary 8740 chrome moly steel, offering a substantial 220,000 psi tensile strength. This level of strength is crucial for maintaining consistent clamping force on your engine block, especially when you're pushing your engine beyond stock performance levels. These studs feature a 12-point external wrenching head, which makes them easier to install and remove compared to standard hex heads, particularly in tight engine bays where access can be a challenge.

When you're rebuilding or modifying an engine, especially one that will see higher cylinder pressures or increased boost, the factory head bolts can become a weak point. They can stretch under load, leading to gasket leaks and potential engine damage. This ARP head stud kit replaces those weaker factory bolts with much stronger, more reliable studs. The studs thread directly into the block, and the cylinder head is then secured with a nut and washer, providing a more even and consistent clamping load across the entire cylinder head surface. This improved clamping is key to preventing head gasket failures and ensuring the integrity of your engine build.

This kit includes all the necessary studs, nuts, and washers for a complete installation. It's a well-built component that's a popular choice for serious engine builders who demand reliability and performance. Always refer to the manufacturer's installation instructions for proper torque specifications and procedures to ensure the best results for your engine build.
