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 of lesser-quality studs from other manufacturers who just dump pieces in a basket and hope for the best. Following heat treatment, 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\u003eVehicle Compatibility:\u003cbr\u003e\u003cbr\u003e- Mitsubishi Lancer Evolution I CE9A\u003cbr\u003e- Mitsubishi Lancer Evolution II CD9A\u003cbr\u003e\u003cspan\u003e- Mitsubishi Lancer Evolution IV\/V\/VI CN9A\/CP9A\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Mitsubishi Lancer Evolution VII\/VIII\/IX CT9A\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Mitsubishi Lancer Evolution GTA CT9A\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Mitsubishi Lancer Evolution Wagon CT9W\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":45773499957447,"sku":"207-5401","price":169.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0508\/9312\/7879\/files\/arp-2000-main-stud-kit-fits-mitsubishi-lancer-evolution-2-9-cd9a-cn9a-cp9a-ct9a-ct9w-4g63-909.webp?v=1763094786","url":"https:\/\/justjap.com\/products\/arp-8740-main-stud-kit-fits-mitsubishi-lancer-evolution-2-9-cd9a-cn9a-cp9a-ct9a-ct9w-4g63","provider":"Just Jap","version":"1.0","type":"link"}
