Fits

Due to their simplicity, durability, and power, the 5.9 12V will forever be a favorite for diesel enthusiasts and is considered to be the holy grail of the Cummins world. However, head bolts are a common failure point on these trucks, especially if you plan on doing a lot of power modifications. These studs, do not stretch, give you more thread engagement for more accurate torque readings and hold up to extreme stress.
