Upgrading to these head studs helps avoid the common head gasket failure issues that arise when you start adding more horsepower and torque to your Super Duty. The 8740 Chromoly Steel construction with an added proprietary element is more durable and will not stretch like the factory bolts. The threads are rolled after heat-treating to provide optimum fatigue strength. These heavy-duty, reusable head studs are rated at a 220,000 PSI tensile strength to ensure better clamping force under higher combustion pressures to help prevent a lifted cylinder head or a failed head gasket.\u003cbr\u003e\u003cbr\u003eIn addition to the increased strength, replacing the factory head bolts with studs also allows you to obtain a more precise torque reading. A conventional bolt gets twisted as it is tightened, so it's reacting to two different forces at the same time. With a stud the force gets applied to the vertical axis, resulting in a more even clamping force. These studs are a must-have for high-horsepower applications and are reusable, unlike the OEM Torque-To-Yield (TTY) bolts which must be replaced after each use. Another benefit of studs is they provide for easier engine assembly and proper alignment of the cylinder heads every time. For a hassle-free installation, each set includes installation instructions.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003ch5\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e220K PSI Tensile Strength\u003c\/li\u003e\n\u003cli\u003eThreads Rolled After Heat Treating\u003c\/li\u003e\n\u003cli\u003eWill Not Stretch Like The Factory Studs\u003c\/li\u003e\n\u003cli\u003e10mm Studs Test Out At A Max Load: Over 120KN\u003c\/li\u003e\n\u003cli\u003eHigh-Strength 8740 Chromoly Steel Construction With Added Proprietary Element\u003c\/li\u003e\n\u003cli\u003eStuds Are Reusable, Unlike Torque-To-Yield (TTY) Bolts Which Much Be Replaced After Each Use\u003c\/li\u003e\n\u003cli\u003eIncludes Washers \u0026amp; 12-Point Nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003eTECH TIPS:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eXDP Thread Cleaning Chasers (Sold Separately):\u003c\/span\u003e\u003cbr\u003eThe XD40127TC (for head studs) and XD40128TC (for inner row bolts) are a great add-on that will be critical during installation. Thread Cleaning Chasers are an excellent tool to have on-hand to ensure you have properly cleaned the threads in your engine block before the installation of any fasteners. Clean threads provide accurate torque readings and will help give you peace of mind during your engine build or head gasket repair.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003eFastener Assembly Lubricant (Sold Separately):\u003c\/span\u003e\u003cbr\u003eThe use of assembley lubricant is highly recommended during engine assembly. Apply lubricant to head studs, head bolts, main studs, main bolts, connecting rod bolts, and any other fasteners used during engine assembly. Using a proper assembly lubricant during fastener installation reduces friction and torque pre-load scatter in the torquing sequence, while also helping to prevent thread galling and seizing.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cmp-product-force-font\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"cmp-product-force-font\"\u003e\n\u003ca href=\"https:\/\/www.xtremediesel.com\/xtreme-diesel-performance-xdp-product-warranty-availability#warranty\"\u003e\u003cspan\u003e\u003cstrong\u003e\u003cu\u003eManufacturer Warranty*:\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003cbr\u003e2 Year \/ Unlimited Mileage\u003c\/div\u003e\n\u003cdiv data-hook=\"variant_changed__data\" data-contentsection=\"render_carb_restriction\" class=\"cmp-product-force-font\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv id=\"product-application-note\" class=\"cmp-product-force-font\"\u003e\n\u003cspan\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003eAssembly lubricant sold separately.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"XDP MFG","offers":[{"title":"Default Title","offer_id":51303185023264,"sku":"XD3004HS","price":484.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3043\/6640\/files\/xdp-xd3004hs-x220-series-head-stud-kit-2008-2010-power-stroke-3713523.jpg?v=1779541690","url":"https:\/\/www.southerndieselsupply.com\/products\/xdp-xd3004hs-x220-series-head-stud-kit-2008-2010-power-stroke","provider":"Southern Diesel Supply","version":"1.0","type":"link"}
