That’s why ARP Pro Series Head Studs are the first choice among top engine builders and racers around the world. Whether you're running a naturally aspirated setup or pushing serious boost, these head studs are engineered to provide superior clamping force, ensuring your cylinder head stays sealed tightly to the block under extreme loads. They eliminate the common issues caused by head lift and gasket failure, especially in high-horsepower or turbocharged applications.\u003c\/p\u003e\n\u003cp\u003eEach stud in this ARP kit is made from premium-grade 8740 chromoly steel, which is heat-treated to an incredible 200,000 psi tensile strength. After heat-treatment, the studs are centerless ground for perfect concentricity, ensuring easy and accurate installation every time. Unlike lower-quality alternatives, ARP studs are thread-rolled after heat-treatment, which improves fatigue strength by up to 1000%—making them exceptionally durable and reliable in the harshest conditions. This attention to detail ensures consistent torque readings, uniform clamping force, and long-term reliability for your engine build. ARP studs are the gold standard in engine fasteners and are stamped with the ARP logo as a guarantee of quality and performance.\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\u003eRated to 200,000 psi tensile strength\u003c\/li\u003e\n\u003cli\u003eMade from premium 8740 alloy steel\u003c\/li\u003e\n\u003cli\u003eCenterless ground for perfect alignment\u003c\/li\u003e\n\u003cli\u003eThread rolled after heat-treatment\u003c\/li\u003e\n\u003cli\u003eDelivers 10x fatigue strength over OEM\u003c\/li\u003e\n\u003cli\u003ePrevents blown head gaskets at high boost\u003c\/li\u003e\n\u003cli\u003eIdeal for high horsepower KA24E builds\u003c\/li\u003e\n\u003cli\u003eTrusted by top professional engine builders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTensile Strength: 200,000+ psi\u003c\/li\u003e\n\u003cli\u003eMaterial: Premium 8740 Chrome Moly\u003c\/li\u003e\n\u003cli\u003eSteel Thread Type: Metric\u003c\/li\u003e\n\u003cli\u003eFinish: Black Oxide Coated\u003c\/li\u003e\n\u003cli\u003eHead Style: 12-Point Nuts\u003c\/li\u003e\n\u003cli\u003eWasher Type: Hardened Parallel\u003c\/li\u003e\n\u003cli\u003eWashers Fastener Style: Stud\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\u003e1989–1990 Nissan 240SX S13 2.4L KA24\u003c\/li\u003e\n\u003cli\u003e1990–1994 Nissan D21 Pickup 2.4L KA24E \u003c\/li\u003e\n\u003cli\u003e1995–1997 Nissan Pickup 2.4L KA24E \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":46674818695325,"sku":"202-4307","price":194.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/202-4307-removebg-preview.png?v=1744745168","url":"https:\/\/rudysdiesel.com\/products\/arp-head-stud-kit-for-1989-1997-nissan-240sx-pickup-2-4l-ka24e-sohc-4-cycl","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
