Replacing the factory head bolts is crucial when increasing horsepower and torque in your Super Duty. The OEM head bolts often fail to handle the extra pressure in high-performance applications, leading to cylinder head lifting. The XDP head studs ensure the cylinder heads remain securely in place, preventing head gasket failures.\u003c\/p\u003e\n\u003cp\u003eConstructed from 8740 Chromoly Steel with an added proprietary element, these studs offer superior durability and will not stretch like stock bolts. The threads are rolled after heat-treating to provide maximum fatigue strength. Rated at 205,000+ psi yield strength and 225,000+ psi tensile strength, these studs guarantee a strong hold under higher combustion pressures.\u003c\/p\u003e\n\u003cp\u003eSwitching to head studs allows for more precise torque readings. Unlike bolts that twist and react to multiple forces, studs apply force along the vertical axis, ensuring even clamping force. This upgrade also simplifies engine assembly and ensures proper alignment of the cylinder heads every time. Unlike OEM Torque-To-Yield (TTY) bolts that need replacement after each use, these studs are reusable, making them ideal for high-performance applications. Manufactured in an ISO\/TS 16949 quality control facility, the kit includes 12-point nuts, washers, and installation instructions for hassle-free setup. Assembly lubricant is sold separately.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e XD3018HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e XD3018HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e XDP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 8740 Chromoly Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Diesel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 Year \/ Unlimited Mileage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProp 65:\u003c\/strong\u003e WARNING: Cancer \u0026amp; Reproductive Harm - P65Warnings.ca.gov\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Washers \u0026amp; 12-Point Nuts:\u003c\/strong\u003e Complete installation kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYield Strength:\u003c\/strong\u003e 205,000-215,000 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile Strength:\u003c\/strong\u003e 225,000-233,000 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Rolled After Heat Treatment:\u003c\/strong\u003e Enhances fatigue strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Strength Construction:\u003c\/strong\u003e 8740 Chromoly Steel with added proprietary element.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReusable Studs:\u003c\/strong\u003e Unlike Torque-To-Yield (TTY) OEM bolts, which are single-use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Load Testing:\u003c\/strong\u003e 10mm studs tested to over 120KN.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO\/TS 16949 Quality Control:\u003c\/strong\u003e Ensures high manufacturing standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEase of Installation:\u003c\/strong\u003e Provides proper alignment of cylinder heads.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitments\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e2011-2023 Ford F-250 Super Duty\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e2011-2023 Ford F-350 Super Duty\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e2011-2023 Ford F-450 Super Duty\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e2011-2023 Ford F-550 Super Duty\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"XDP","offers":[{"title":"Default Title","offer_id":45681723867293,"sku":"XD3018HS","price":539.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/1_b0c08d95-4eaf-46f8-8ec1-e0dd599f468d.jpg?v=1720778189","url":"https:\/\/rudysdiesel.com\/products\/xdp-x220-series-head-stud-kit-xd3018hs-for-2011-2023-ford-f-250-350-450-550-super-duty","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
