Simply stated, there’s not a better stud setup \u003cbr\u003e on the market today. \u003cbr\u003e For openers, ARP only uses premium grade 8740 alloy and \u003cbr\u003e a proprietary ARP2000® alloy that are rated far superior to “aircraft” \u003cbr\u003e quality alloy steels. Secondly, each stud is placed vertically \u003cbr\u003e into special racks and precisely heat-treated to 190,000 psi for \u003cbr\u003e the 8740 material and 220,000 psi for the ARP2000® material. \u003cbr\u003e This procedure ensures complete heat penetration and the results \u003cbr\u003e are far superior to those lesser quality studs from other manufacturers \u003cbr\u003e who just dump pieces in a basket and hope for the best. \u003cbr\u003e Following heat-treat, each stud is centerless ground to make \u003cbr\u003e it as close to perfectly concentric as possible. This procedure \u003cbr\u003e involves about ten very slight cuts and results in an exceptionally \u003cbr\u003e straight part. It’s important to note that lesser quality studs \u003cbr\u003e are not even centerless ground – the material is thread rolled in \u003cbr\u003e bar stock form (mostly before heat-treat, when the material is \u003cbr\u003e easier to machine). Because ARP studs are manufactured to such \u003cbr\u003e exacting tolerances, you will note that gaskets and cylinder heads \u003cbr\u003e literally glide into position and are perfectly aligned – something \u003cbr\u003e that won’t happen with inferior quality head studs. \u003cbr\u003e ARP studs are thread rolled after heat-treat, which gives them \u003cbr\u003e about 2000% (that’s twenty times) better fatigue strength than \u003cbr\u003e those studs that are threaded prior to heat-treat (a very common \u003cbr\u003e industry practice). It costs a lot more to do it this way, because it’s \u003cbr\u003e tough on tooling, but the results are well worth the extra effort. \u003cbr\u003e You will also note that ARP offers specially undercut studs for \u003cbr\u003e several engines. This procedure (done only to the shorter studs) \u003cbr\u003e more equalizes the “stretch” of both studs, which makes for a \u003cbr\u003e more consistent clamping force – and one that compensates for \u003cbr\u003e head gasket compression when the cylinder heads are installed. \u003cbr\u003e This helps prevent blown head gaskets, and assures optimum \u003cbr\u003e engine sealing! \u003cbr\u003e Premium quality 8740 and ARP2000® head stud kits are available \u003cbr\u003e for most domestic and import applications. You won’t find a \u003cbr\u003e better quality stud on the market from any other source. Look for \u003cbr\u003e ARP stamped on each stud as your assurance of quality. \u003cbr\u003e Clearly, they are the best on the market today, and the favorite \u003cbr\u003e of leading professional engine builders in all forms of racing.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eMaterial: Custom Age 625+\u003c\/li\u003e\n\u003cli\u003eFinish: Natural\u003c\/li\u003e\n\u003cli\u003eMaterial 2: \u003c\/li\u003e\n\u003cli\u003eFinish 2: \u003c\/li\u003e\n\u003cli\u003eOrigin: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":46243956621508,"sku":"ARP 203-4301","price":674.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/6216\/6212\/files\/arp_203-4301_001.jpg?v=1781275769","url":"https:\/\/wktuning.com\/products\/cylinder-head-stud-kit-for-toyota-3-0l-2jzge-gte-inline-6-1993-98-supra-custom-age-625","provider":"WK Performance","version":"1.0","type":"link"}
