Engineered specifically for the 2.4L, 2.6L, and 2.8L inline-six motors found in the iconic 240Z, 260Z, 280Z, and 280ZX models, these studs are built to handle high compression, forced induction, and extreme stress. Each stud is precision-crafted from premium-grade 8740 chromoly steel, heat-treated to 200,000 psi tensile strength, and centerless ground for exceptional straightness. Whether you're building a high-revving NA setup or a turbocharged beast, ARP studs deliver the strength and precision you need for maximum sealing and reliability.\u003c\/p\u003e\n\u003cp\u003eARP’s commitment to performance and durability is evident in every aspect of this Pro Series kit. Unlike inferior studs that can warp or fail under pressure, ARP studs are thread-rolled after heat treatment for superior fatigue resistance—up to 20 times stronger than cheaper alternatives. The kit includes 12-point nuts and parallel-ground hardened washers to ensure even load distribution and consistent torque readings. Designed to eliminate head lift and prevent blown head gaskets, ARP Pro Series head studs are the trusted choice of professional engine builders and racers alike. If you’re serious about power and reliability, this is the head stud kit your L-series engine deserves.\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 alloy\u003c\/li\u003e\n\u003cli\u003eHeat-treated to 200,000 psi tensile strength\u003c\/li\u003e\n\u003cli\u003eCenterless ground for perfect concentricity\u003c\/li\u003e\n\u003cli\u003eThread rolled after heat treatment for strength\u003c\/li\u003e\n\u003cli\u003eIncludes 12-point nuts and hardened washers\u003c\/li\u003e\n\u003cli\u003eEnsures precise head-to-block alignment\u003c\/li\u003e\n\u003cli\u003eResists stretching under high-performance loads\u003c\/li\u003e\n\u003cli\u003eTrusted by pro engine builders worldwide\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: No\u003c\/li\u003e\n\u003cli\u003eHead Style: 12-point\u003c\/li\u003e\n\u003cli\u003eFastener Material: 8740 chromoly\u003c\/li\u003e\n\u003cli\u003eFastener Color: Black\u003c\/li\u003e\n\u003cli\u003eWashers Included: Yes\u003c\/li\u003e\n\u003cli\u003eQuantity: Sold as a kit\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\u003e1970–1973 Datsun\/Nissan 240Z 2.4L L24\u003c\/li\u003e\n\u003cli\u003e1974-1975 Datsun\/Nissan 260Z 2.6L L26\u003c\/li\u003e\n\u003cli\u003e1975–1978 Datsun\/Nissan 280Z 2.8L L28\u003c\/li\u003e\n\u003cli\u003e1979–1983 Datsun\/Nissan 280ZX 2.8L L28E\/L28ET\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\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":46671505424541,"sku":"202-4206","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/Screenshot2025-04-14101416_9813e755-fdf1-4b52-bf72-278e9a1144dc.png?v=1744643964","url":"https:\/\/rudysdiesel.com\/products\/arp-pro-series-head-studs-kit-for-70-83-240z-260z-280z-280zx-2-4l-2-6l-2-8l","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
