1998.5-2021 Cummins Competition Head Stud Kit.
5.9 or 6.7, the Cummins is a beloved engine among many diesel enthusiasts, and for good reason. However, there is always that looming threat whenever you want to make more power; head bolts.
While under extreme stress whether it’s stock or heavily modified, these bolts can stretch and blow your gaskets. Solution; these studs have a higher clamping capacity which gives them superior strength to withstand more stress, and won’t twist when you tighten them.
So if you want more performance upgrades, you better get some studs.
