Simply stated, there’s not a better stud setup on the market today. For openers, ARP uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality. Each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.\u003c\/span\u003e\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":52879515222383,"sku":null,"price":655.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/2405\/8991\/files\/image-2a2fa471_7ff92a8a-86ee-4d97-b430-482f73355449.webp?v=1776364600","url":"https:\/\/newworldoil.myshopify.com\/products\/arp260-4704-subaru-ej-series-dohc-custom-age-head-stud-kit","provider":"New World Oil","version":"1.0","type":"link"}
