Product Details
ARP makes this Stainless Steel Head Stud Kit for the Porsche 911 and 930 turbo engines. If you're building or rebuilding a turbocharged 911 engine, especially one that will see higher boost pressures, you need head studs that can handle the extra stress. These ARP studs are a solid upgrade over the factory head bolts, ensuring your cylinder heads stay sealed under demanding conditions.
This kit uses ARP's 8740 alloy steel, heat-treated to 200,000 psi tensile strength. The threads are rolled after heat treatment, which makes them stronger and less prone to fatigue than threads that are cut. The kit includes the necessary nuts and washers, all made from quality materials to match the studs.
