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.
- HD220 High-Strength Material - Proprietary alloy delivers superior strength and fatigue resistance, far exceeding OEM and 8740 chromoly
- 14mm Main Stud Upgrade - Designed specifically for 1989-1997 Dodge 5.9L Cummins 12V engines with 14mm main cap fasteners
- Superior Clamp Load - Provides exceptional main cap retention, preventing main cap walk and bottom-end failure under high power
- Corrosion Resistant - Black oxide finish protects against rust and harsh diesel environments
- Direct ARP 247-5402 Alternative - Outperforms ARP's 8740 chromoly (190k-200k PSI) with HD220's 220,000+ PSI tensile strength
- Fitment Note - Will not fit 1997.5+ trucks with 12mm studs. For those, use MSK5924. 14mm engines have one turbo oil drain port; 12mm have two
- Gator Fasteners Quality - Backed by Gator Fasteners' commitment to strength and reliability - Nothing Bites Like Gator
