ARP Head Stud Kit 425+ for 01-17 Duramax 6.6L

Protect the head gaskets on your 01-18 Duramax LB7/LLY/LBZ/LMM/LML with the ARP Head Studs we have been using for over 8 years!
Pricing: $570.00


With the widespread use of aftermarket components and tuning now popular on diesel trucks, blown head gaskets are becoming the standard and not the exception.  The increased performance of these trucks are putting additional stress on OEM components that weren't designed to handle it.

ARP has designed their 2000 series head stud line to provide an affordable solution to building reliable protection into your cylinder heads for whatever performance upgrades you can dream up.  These studs feature 220,000 psi of tensile strength to combat the increased combustion pressures from tuning, fuel, and turbo upgrades.

We have installed the ARP 2000 series studs on thousands of 6.6L Duramax motors and have never had an issue directly related to the failure of these components.  Note! We highly recommend replacing your cylinder heads during this repair due to the high likelihood that the surface of the existing head is not flat.  This will compromise the functionality of the head studs!
