2008-2010 6.4L Ford Powerstroke ARP Head Studs Set
No better cylinder head studs available at any cost.
ARP fasteners makes the best and stronger engine head studs on the market today.
Your 6.4 came from the factory with head bolts.
The factory head bolts were designed to stretch but over time the bolts stretch past the designed length and allow the gaskets to leak.
With ARP head studs there is no more stretch and therefor no longer issues with blown head gaskets.
