When you invest in 5.9L/6.7L Cummins, you’re planning to keep it on the road for the long haul. At some point in the life of that engine, the factory head screws will need to be upgraded to head studs. Thoroughbred Diesel makes this easy with their premium Head Stud Kit for your 1998.5-2025 Dodge 2500/3500 as it was specifically designed to strengthen up your truck’s entire assembly without compromise. Thoroughbred Diesel’s head studs were built much stronger than the OE head screws and will not stretch like their factory counterparts. This will prevent your truck from popping head gaskets during high-pressure situations
