{"product_id":"cylinder-head-stud-kit-1","title":"Cylinder Head Stud Kit","description":"The ARP 256-4702 is a specialized head stud kit engineered for the Ford 5.0L Coyote engine. Built with ARP 2000 material, these studs undergo heat treatment before thread rolling and machining, achieving a tensile strength rating of 220,000 psi. This provides significantly increased strength and reliability compared to standard head bolts.\n\nIt features a durable black oxide finish for corrosion resistance and comes complete with 12-point nuts and hardened parallel washers. The washers ensure even load distribution across the cylinder head deck, contributing to more accurate torque readings during installation.\n\nARP head studs are cold-forged to guarantee molecular integrity throughout the fastener. This process, combined with the ARP 2000 material, makes this kit suitable for forced induction and nitrous applications, as well as engines operating with over 20lbs of boost. Installation instructions are available for download from ARP's website.","brand":"ARP Cylinder","offers":[{"title":"Default Title","offer_id":52686968717624,"sku":"ARP-256-4702","price":409.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660676433.jpg?v=1784879058","url":"https:\/\/store.motormia.co\/products\/cylinder-head-stud-kit-1","provider":"MOTORMIA","version":"1.0","type":"link"}
