When building your 1989-1998 Dodge 5.9L Cummins diesel engine, the Gator Fasteners HSK5912 Heavy Duty Head Stud Kit is a critical upgrade. Unlike factory head bolts, which are prone to stretching and can lead to blown head gaskets, these heavy-duty head studs provide significantly higher strength and durability. With a tensile strength of over 220,000 PSI and a maximum load capacity of over 120KN, they are designed to keep your cylinder head securely clamped down, protecting your engine from catastrophic head gasket failure, especially in stock to moderately built engines.
