Their Pro Series head studs for the Audi 30V 2.7T engine are crafted from ARP 2000 alloy—an exceptionally strong material designed to hold up under the extreme pressure and heat of high-boost applications. Each stud is heat-treated to 220,000 psi, then thread rolled post-treatment to dramatically increase fatigue strength—up to 20 times stronger than lower-grade alternatives.\u003c\/p\u003e\n\u003cp\u003eManufactured in the U.S.A., these studs are engineered for durability, precision, and reusability, making them perfect for high-performance and race builds. ARP's reputation for quality and precision ensures that your cylinder heads stay firmly sealed under extreme loads, reducing the risk of head lift and blown gaskets. When reliability matters most, ARP delivers unmatched performance you can count on.\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 ultra-strong ARP 2000 alloy steel\u003c\/li\u003e\n\u003cli\u003eHeat treated to an incredible 220,000 psi tensile strength\u003c\/li\u003e\n\u003cli\u003eThread rolled after heat treat for max fatigue resistance\u003c\/li\u003e\n\u003cli\u003eMaintains head seal under high boost pressure\u003c\/li\u003e\n\u003cli\u003e100% reusable—ideal for race engine rebuilds\u003c\/li\u003e\n\u003cli\u003eDesigned for precise fitment and perfect alignment\u003c\/li\u003e\n\u003cli\u003eIncludes parallel ground washers for even torque\u003c\/li\u003e\n\u003cli\u003eManufactured in the U.S.A. with strict quality control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFastener Style: Stud\u003c\/li\u003e\n\u003cli\u003eUndercut Stud: Yes\u003c\/li\u003e\n\u003cli\u003eHead Style: 12-Point Nut\u003c\/li\u003e\n\u003cli\u003eFastener Material: ARP 2000 Alloy Steel\u003c\/li\u003e\n\u003cli\u003eFastener Color: Black Oxide\u003c\/li\u003e\n\u003cli\u003eIncluded: Studs, 12-Point Nuts, Parallel Ground Washers\u003c\/li\u003e\n\u003cli\u003eQuantity: Kit (for complete cylinder head installation)\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) Head 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\u003e2000-2004 Audi A6 Quattro 2.7L Base\u003c\/li\u003e\n\u003cli\u003e2001-2005 Audi Allroad Quattro 2.7L Base\u003c\/li\u003e\n\u003cli\u003e2001-2002 Audi S4 2.7L Avant\u003c\/li\u003e\n\u003cli\u003e2000-2002 Audi S4 2.7L Base \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eLifetime Warranty  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":46671900278941,"sku":"204-4105","price":474.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/Screenshot2025-04-14153839.png?v=1744661533","url":"https:\/\/rudysdiesel.com\/products\/arp-pro-series-head-stud-kit-for-2000-2004-audi-a6-s4-2-7l-bi-turbo-v6","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
