All kits come complete with hardened parallel-ground washers and high quality nuts. Some applications have provisions for mounting windage trays and have specially designed standoff studs with serrated lock nuts to position the windage tray and lock it securely in place. The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 200,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.\u003c\/p\u003e\n\u003cdiv id=\"gmail-description\"\u003e\n\u003cdiv id=\"gmail-descriptioncontent\"\u003e\n\u003cdiv\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eMade from premium 8740 chromoly steel\u003c\/li\u003e\n\u003cli\u003eHeat-treated to 200,000 psi tensile strength\u003c\/li\u003e\n\u003cli\u003eJ-form rolled threads for extreme fatigue strength\u003c\/li\u003e\n\u003cli\u003eThreads are 1000% stronger than OEM fasteners\u003c\/li\u003e\n\u003cli\u003eIncludes aerospace-grade 12-point nuts\u003c\/li\u003e\n\u003cli\u003eHardened parallel-ground washers included\u003c\/li\u003e\n\u003cli\u003eReduces crankshaft flex and main cap fretting\u003c\/li\u003e\n\u003cli\u003eComplete hardware for main bolt-to-stud upgrade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFastener Material: 8740 Chrome Moly\u003c\/li\u003e\n\u003cli\u003eFastener Style: Stud\u003c\/li\u003e\n\u003cli\u003eFastener Finish: Black Oxide\u003c\/li\u003e\n\u003cli\u003eHead Style: 6 Point (Hex)\u003c\/li\u003e\n\u003cli\u003eMain Cap Type: 2 Bolt\u003c\/li\u003e\n\u003cli\u003eUndercut Stud\/Bolt: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Main Stud Kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e1990-1997 Mazda Miata 1.6L\u003c\/li\u003e\n\u003cli\u003e1999-2005 Mazda Miata 1.8L \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eLifetime Warranty  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":46674478792861,"sku":"218-5401","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/218-5401.png?v=1744733585","url":"https:\/\/rudysdiesel.com\/products\/arp-main-stud-kit-2-bolt-8740-chrome-moly-for-1990-2005-mazda-miata-1-6l-1-8l","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
