{"product_id":"torquemaster-14mm-head-stud-kit","title":"TorqueMaster 14mm Head Stud Kit","description":"The OptiTorque 10398 TorqueMaster 14 mm Head Stud Kit provides a robust clamping solution for performance-built 5.9L and 6.7L 24v and Common Rail Cummins diesel engines. These fasteners are forged from vacuum-melted, micro-alloyed American HSLA steel and are fully stress-relieved before being centerless ground to achieve maximum straightness and cycle fatigue resistance. Each fastener is finished with a hot-temperature oil dip and a brilliant black oxide coating for superior corrosion protection.\n\nThis kit is specifically engineered for engines already modified to accept 14 mm head studs. Installation is streamlined by a bottoming boss on the block-side threads, which eliminates the need for specialized tools during the assembly process. The package includes high-strength 12-point nuts, precision-ground washers to optimize load distribution, TrueTorq assembly lubricant, and detailed installation procedures.\n\nCompatibility is limited to 1998.5–2022 Dodge Cummins 5.9L and 6.7L models that have been pre-machined for 14 mm studs. These studs do not fit engines configured for factory-standard fastener sizes without additional machine work. Because these parts are engineered based on OEM tolerances, custom or aftermarket engine modifications may require specific length alterations or fitment adjustments. Always verify engine block configuration before attempting installation.","brand":"Optitorque","offers":[{"title":"Default Title","offer_id":52663201005880,"sku":"OTT 10398","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687521200.jpg?v=1784324851","url":"https:\/\/store.motormia.co\/products\/torquemaster-14mm-head-stud-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
