When pushing the limits of your 2003-2007 Dodge 5.9L Common Rail Cummins, the last thing you want to worry about is a catastrophic bottom-end failure. Your engine's main studs are a critical weak point, and under the immense pressure of high horsepower, towing, or racing, the factory hardware can simply give way. This leads to main cap walk and devastating damage. The Gator Fasteners Main Stud Kit is the ultimate upgrade, meticulously engineered to provide superior clamp load and protect your investment. With our proprietary HD220 alloy, these main studs deliver over 220,000 PSI tensile strength, significantly outperforming standard ARP 8740 chromoly studs.
This comprehensive kit is a direct-fit solution that will transform the reliability of your engine.
