{"product_id":"xd3004hs","title":"XDP X220 Series Head Stud Kit XD3004HS","description":"\u003cp\u003eReplace the OEM head bolts in your 2008-2010 Ford 6.4L Powerstroke with the XDP X220 Series Head Stud Kit XD3004HS. 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.\u003c\/p\u003e\n\u003cp\u003eThe 8740 Chrome Moly 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.\u003c\/p\u003e\n\u003cp\u003eThese heavy-duty, reusable head studs are rated at 220,000 plus psi tensile strength and 210,000 plus yield strength to ensure better clamping force under higher combustion pressures to help prevent a lifted cylinder head or a failed head gasket.\u003c\/p\u003e\n\u003cp\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.\u003c\/p\u003e\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\u003cp\u003eAnother benefit of studs is they provide for easier engine assembly and proper alignment of the cylinder heads every time. To ensure maximum quality the studs are manufactured in an ISO\/TS 16949 quality control facility. For a hassle-free installation, each set includes installation instructions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes Washers and 12 Point Nuts\u003c\/li\u003e\n\u003cli\u003eYield Strength: 210,000-230,000 PSI\u003c\/li\u003e\n\u003cli\u003eTensile Strength: 220,000-236,000 PSI\u003c\/li\u003e\n\u003cli\u003eThreads Rolled After Heat Treatment\u003c\/li\u003e\n\u003cli\u003eReusable Studs, Unlike TTY OEM Bolts\u003c\/li\u003e\n\u003cli\u003e10mm Studs Test Out At Max Load Of Over 120KN\u003c\/li\u003e\n\u003cli\u003eManufactured In ISO\/TS 16949 Quality Control Facility\u003c\/li\u003e\n\u003cli\u003e8740 Chrome Moly Construction With Added Proprietary Element\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eXDP Thread Cleaning Chasers (Sold Separately):\u003c\/strong\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\/p\u003e","brand":"XDP Xtreme Diesel Performance","offers":[{"title":"Default Title","offer_id":47077777572124,"sku":"XD3004HS","price":750.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0092\/1619\/6665\/products\/XD3004HS-HVCD.jpg?v=1697812652","url":"https:\/\/holdersdiesel.com\/en-ca\/products\/xd3004hs","provider":"Holders Diesel Performance","version":"1.0","type":"link"}
