The ARP Diesel Head Stud Kit 230-4201 is a must-have in any high-performance 2001-2016 GM 6.6L Duramax. To overcome head gasket failures that can occur in diesel engines in these high-performance applications, industry leader ARP has introduced extra heavy-duty head studs for the popular GM LB7, LLY, LBZ, LMM, LML Duramax powerplants.
 
The 230-4201 ARP studs are rated at 220,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures.
