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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEach 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. Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground; the material is thread rolled in bar stock form (mostly before heat-treat when the material is easier to machine).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBecause ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned, something that won’t happen with inferior-quality head studs.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eEngine Compatibility: \u003cbr\u003e\u003cbr\u003e- Subaru WRX VAG 2015-2021 (FA20E)\u003cbr\u003e- Subaru Forester SJ 2013-2018 (FA20E)\u003cbr\u003e- Subaru Levorg VMG 2014-2020 (FA20E)\u003cbr\u003e- Subaru BRZ 2012-2021 ZC6 (FA20C\/FA20D)\u003cbr\u003e- Toyota 86 2012-2021 ZN6 (FA20D)\u003cbr\u003e\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":39306184982727,"sku":"260-4301","price":529.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0508\/9312\/7879\/files\/arp-8740-head-stud-kit-fits-subaru-wrx-va-levorg-vm-forester-sj-brz-toyota-86-fa20-842.jpg?v=1782192484","url":"https:\/\/justjap.com\/products\/arp-8740-head-stud-kit-fits-subaru-wrx-va-levorg-vm-forester-sj-brz-toyota-86-fa20","provider":"Just Jap","version":"1.0","type":"link"}
