The kit's single biggest selling point is its use of XOTIC 7200 material rated at 220,000 psi, which delivers significantly more tensile strength than common chromoly studs; that strength, combined with centerless ground concentricity and rolled threads after heat treat, makes this a practical upgrade for performance or reliability-minded builders.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eDirect fit replacement:\u003c\/strong\u003e Designed specifically for 1998.5-present Dodge Cummins 5.9L and 6.7L 24V engines to simplify installation and ensure accurate fitment.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUltra strength construction:\u003c\/strong\u003e Machined from XOTIC 7200 material and rated at 220,000 psi to provide greater tensile strength and reduce the risk of head lifting under boost.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFatigue-resistant threads:\u003c\/strong\u003e Threads are rolled after heat treatment to optimize fatigue strength and maintain clamping force over time.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eEasy installation features:\u003c\/strong\u003e Broached stud ends and included installation manual with drawn diagrams make removal and installation more straightforward.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eComplete kit contents:\u003c\/strong\u003e Ships with 26 studs, 26 nuts, 26 hardened parallel washers, assembly lubricant, and an instructions manual so users have all necessary hardware.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eProtective finish and washers:\u003c\/strong\u003e Black oxide finish and hardened parallel washers help with uniform load distribution and accurate torque readings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is ideal for diesel owners and mechanics who run high-performance turbo setups, frequently tow, or otherwise place high cylinder pressures on a 24V Cummins head.
