Head Studs

Note: If you are running a VGT Turbocharger, the 625's are the only thing proven to hold.


Let's face it, nobody wants to be tearing apart their Cummins to do the headgasket and studs. It's expensive, meticulous, and time-consuming - so if you're already in there, make sure you do the job right with ARP Head Studs. ARP has continually proven themselves to be the only head stud you can trust with your 6.7L Cummins.
