Replacing the stock bolts with studs helps keep the head gasket sealed when the engine is running with higher turbo pressure or increased compression.\u003c\/p\u003e\u003cp\u003eThey are manufactured from ARP2000, a proprietary alloy from ARP that reaches approximately 220,000 psi tensile strength and retains its properties under heat better than chrome-moly. The threads are rolled after heat treatment, which gives ARP studs superior fatigue strength, and the final grinding ensures that the head and gasket seat perfectly aligned during installation.\u003c\/p\u003e\u003cp\u003eUse ARP's assembly lubricant and their torque specifications, as the load applied to each part will not be the same with other lubricants. Before ordering, confirm the engine code; if you are not sure, we can help you check it.\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":53894435635534,"sku":"ARP-203-4705","price":545.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/generic_401ed394-5205-4669-8ef4-9ec66a598803.jpg?v=1790662322","url":"https:\/\/driftandgrip.com\/en\/products\/arp-head-bolts-part-no-203-4705","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
