Description
Upgrade the durability and reliability of your 1989–1997 Dodge 5.9L Cummins 12V Diesel engine with the Gator Fasteners HD220 Heavy Duty Main Stud Kit (MSK5912). 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.
Each 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.
Vehicle Compatibility: Fits 1989–1997 Dodge Ram 2500/3500 trucks with 5.9L Cummins 12V Diesel engines using 14mm main cap fasteners.
