Replaces the factory head bolts with studs and nuts, a solution that distributes the load more evenly across the gasket and prevents damage to the block threads each time the cylinder head is removed.\u003c\/p\u003e\u003cp\u003eThey are manufactured from 8740 chrome-moly steel, heat-treated by ARP to a tensile strength of approximately 190,000 psi. Each stud is centerless ground after heat treatment to ensure it is perfectly concentric, allowing the gasket and head to seat in alignment, and the threads are rolled after heat treatment, which ARP states increases fatigue strength by a factor of twenty.\u003c\/p\u003e\u003cp\u003eUse ARP assembly lubricant and their torque specifications, because using a different lubricant will result in a different load on each component. Before ordering, confirm the engine code; if you are unsure, we can help you verify it.\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":53893689803086,"sku":"ARP-207-4201","price":180.48,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/207-4201.jpg?v=1790662665","url":"https:\/\/driftandgrip.com\/en\/products\/arp-head-studs-m12-part-no-207-4201","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
