It replaces the stock head bolts with studs and nuts, a solution that distributes the load more evenly across the gasket and avoids damaging the block threads every time the cylinder head is removed.\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. The threads are rolled after heat treatment, which gives ARP studs superior fatigue resistance, and the final grinding ensures the cylinder head and gasket sit perfectly aligned during assembly.\u003c\/p\u003e\u003cp\u003eUse ARP assembly lubricant and their torque specifications, as the load received by each component varies with other lubricants. Before ordering, confirm your engine code; if you are unsure, we can help you check it.\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":53893809307982,"sku":"ARP-206-4203","price":114.94,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/206-4203.jpg?v=1790662596","url":"https:\/\/driftandgrip.com\/en\/products\/arp-head-studs-part-no-206-4203","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
