ARP head studs increase clamping force and reliability preventing common head gasket failures that are usually attributed to the cylinder pressure increases seen when boosting the performance of your Cummins engine.
Whether you’re already pushing the limits of the stock head bolts or simply wanting to add some reassurance to your build, these studs are a sure way to keep your head fastened to the block preventing costly repairs.
The ARP studs can be installed without removing the cylinder head making for a quick and cost effective replacement!
