Manufactured from Gator’s proprietary HD220 alloy, these 14mm main studs deliver industry-leading tensile strength (over 220,000 PSI), outperforming ARP’s 8740 chromoly (190,000-200,000 PSI) and stock hardware. This translates to exceptional main cap retention, reduced risk of main cap walk, and bottom-end security for high-power, towing, or racing builds.\u003c\/p\u003e\n\u003cp\u003eEach stud features a corrosion-resistant black oxide finish and is precision-machined for a direct fit on 14mm 12V Cummins blocks. Installation is straightforward, but be sure to verify compatibility: this kit fits only 14mm main cap engines (1989–1997). 14mm engines have one turbo oil drain port; 12mm engines (1997.5+) have two. For 1997.5+ engines with 12mm studs, use Gator Fasteners MSK5924.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Compatibility:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFits 1989–1997 Dodge Ram 2500\/3500 trucks with 5.9L Cummins 12V Diesel engines using 14mm main cap fasteners.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHD220 High-Strength Material\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– Proprietary alloy delivers superior strength and fatigue resistance, far exceeding OEM and 8740 chromoly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e14mm Main Stud Upgrade\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– Designed specifically for 1989–1997 Dodge 5.9L Cummins 12V engines with 14mm main cap fasteners\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Clamp Load\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– Provides exceptional main cap retention, preventing main cap walk and bottom-end failure under high power\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Resistant\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– Black oxide finish protects against rust and harsh diesel environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect ARP 247-5402 Alternative\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– Outperforms ARP’s 8740 chromoly (190k-200k PSI) with HD220’s 220,000+ PSI tensile strength\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment Note\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– Will\u003cspan\u003e \u003c\/span\u003e\u003cb\u003enot\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003efit 1997.5+ trucks with 12mm studs.
