OEM main bolts often fail under the pressure of high-horsepower engines. This kit, constructed from 8740 Chromoly with an added proprietary element, provides superior durability and ensures the studs won't stretch like factory bolts. The threads are rolled after heat-treatment to deliver optimal fatigue strength. Rated at 210,000-230,000 psi yield strength and 220,000-236,000 psi tensile strength, these studs guarantee a strong hold under higher combustion pressures.\u003c\/p\u003e\n\u003cp\u003eReplacing the main bolts with studs allows for more precise torque readings. Unlike bolts that get twisted and react to two different forces simultaneously, studs apply force to the vertical axis, resulting in an even clamping force. This kit is a must-have for high-performance applications and offers reusable studs, unlike OEM Torque-To-Yield (TTY) bolts that must be replaced after each use. Additionally, the studs make engine assembly and proper alignment of the main bearing caps easier and more accurate. Manufactured in an ISO\/TS 16949 quality control facility, this kit includes 12-point nuts, washers, and installation instructions for a hassle-free installation. 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 XD3007MS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e XD3007MS\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 12-Point Nuts \u0026amp; Washers:\u003c\/strong\u003e Complete installation kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYield Strength:\u003c\/strong\u003e 210,000-230,000 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile Strength:\u003c\/strong\u003e 220,000-236,000 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\u003eReusable Studs:\u003c\/strong\u003e Unlike TTY OEM bolts, which are single-use.\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\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\u003c\/ul\u003e\n\u003ch3\u003eFitments\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e2001-2005 Chevrolet Silverado 2500 HD\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e2001-2005 Chevrolet Silverado 3500\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e2001-2005 GMC Sierra 2500 HD\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e2001-2005 GMC Sierra 3500\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"XDP","offers":[{"title":"Default Title","offer_id":45681539121309,"sku":"XD3007MS","price":234.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/1_03443234-f0b0-4734-b8d4-34df65499e3e.jpg?v=1720773750","url":"https:\/\/rudysdiesel.com\/products\/xdp-x220-main-stud-kit-for-2001-2005-chevrolet-gmc-silverado-sierra","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
