It is one of the first upgrades made to an engine that is going to have its power increased, as the head gasket is one of the first points to fail.\u003c\/p\u003e\u003cp\u003eThey are manufactured from 8740 chrome-moly steel, heat-treated by ARP itself to a tensile strength of approximately 190,000 psi. ARP grinds each stud after heat treatment to ensure it is straight and concentric, and rolls the threads at the end of the process; this achieves a fatigue strength about twenty times greater than that of a thread made before heat treatment.\u003c\/p\u003e\u003cp\u003eUse ARP assembly lubricant and their torque specifications, because with any other lubricant the load received by each part is not the same. If you have any doubts about whether this is the correct part number for your engine, write to us with your engine code and year.\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":53893776998734,"sku":"ARP-208-4304","price":300.48,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/208-4304.jpg?v=1790662617","url":"https:\/\/driftandgrip.com\/en\/products\/arp-head-studs-part-no-208-4304","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
