These head studs are made from premium 8740 chrome moly steel, heat-treated to a remarkable 190,000–200,000 psi to provide superior strength and durability. The studs undergo a rigorous manufacturing process, starting with cold-forging to ensure molecular integrity, followed by heat treatment and centerless grinding to guarantee perfect concentricity. The thread rolling process after heat treatment improves fatigue strength, making them significantly stronger than those that are threaded beforehand. This attention to detail ensures these studs can handle high-boost, high-performance setups without fail.\u003c\/p\u003e\n\u003cp\u003eDesigned for the RB20DET, RB25DET, RB25DET NEO, and RB30 dual cam conversion, these head studs are a must-have for any serious engine builder. ARP’s high-quality parallel-ground washers allow for more accurate torque readings and better load distribution, while the 12-point or hex nuts provide reliable and even clamping force to prevent cylinder head lifting. With ARP’s commitment to excellence, you can trust that these studs will keep your engine sealed tight under extreme pressure, preventing blown gaskets and ensuring a long, reliable engine life. Whether you’re rebuilding an older RB engine or pushing your build to the limits, these ARP head studs are a top-tier choice for any high-performance application.\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\u003ePremium 8740 chrome moly steel construction\u003c\/li\u003e\n\u003cli\u003eHeat treated to 190,000–200,000 psi strength\u003c\/li\u003e\n\u003cli\u003eThread rolled after heat treat for max fatigue life\u003c\/li\u003e\n\u003cli\u003eCenterless ground for precision concentricity\u003c\/li\u003e\n\u003cli\u003eHardened parallel washers ensure even load\u003c\/li\u003e\n\u003cli\u003eIncludes 12-point or hex nuts for easy torque\u003c\/li\u003e\n\u003cli\u003eIdeal for RB20\/25\/30 high-boost applications\u003c\/li\u003e\n\u003cli\u003ePerfect alignment for heads and gaskets\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\u003e1990-2002 Nissan Skyline GT-R RB26DETT 2.6L Twin-Turbo\u003c\/li\u003e\n\u003cli\u003e1994-2002 Nissan Skyline GT-T RB25DET 2.5L Turbo\u003c\/li\u003e\n\u003cli\u003e1989-2002 Nissan Silvia RB20DET 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1989-2002 Nissan Silvia RB25DET 2.5L Turbo\u003c\/li\u003e\n\u003cli\u003e1989-2002 Nissan Silvia RB25DET NEO 2.5L Turbo\u003c\/li\u003e\n\u003cli\u003e1989-1998 Nissan 180SX RB20DET 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1989-1998 Nissan 180SX RB25DET 2.5L Turbo\u003c\/li\u003e\n\u003cli\u003e1989-1998 Nissan 240SX RB25DET 2.5L Turbo\u003c\/li\u003e\n\u003cli\u003e1989-1998 Nissan 240SX RB20DET 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1990-2002 Nissan Fairlady Z RB26DETT 2.6L Twin-Turbo\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":46671421112477,"sku":"202-4301","price":209.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/Screenshot2025-04-14101416.png?v=1744641011","url":"https:\/\/rudysdiesel.com\/products\/arp-pro-series-head-studs-kit-for-89-02-nissan-rb20-rb20det-rb25-rb25det-2-0-2-5","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
