6.6L Duramax 
 
Let's face it, nobody wants to be tearing apart their Duramax to do the head gaskets 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 itself to be the only head stud you can trust with your 6.6L Duramax. 

The Custom Aged 230-4202 Studs add another layer of security to your 6.6L Duramax build with extra-strong studs with the Custom Aged 625+ material that has a minimum rating of 260,000 PSI tensile strength. This ensures that even with abnormally high combustion chamber pressure the 230-4202 Custom Aged Studs will provide the clamping strength necessary to keep your cylinder head from lifting.
