ARP 250-4201 Ford 7.3L Powerstroke diesel ft93- ft02 head stud kit

In stock

When does the 7.3 Powerstroke need ARP head studs? A general rule is around the 500hp mark or with hybrid injectors at 238cc and above you should consider installing head studs. What's the best way to prevent blow head gaskets? The first step and only step in prevention are install ARP head studs in place of the factory head bolts . 

Arp Fasteners are the leader in head studs in the diesel performance industry. 7.3 head studs can prevent or eliminate head gasket failures in high performance or high horsepower engines. If you use the factory head gaskets with these studs you can run up to 750 hp+ with proper installation. What are head studs? Head studs are a much stronger solution to the factory head bolts. They are threaded on each end and are made from much strong chrome moly hardened steel. 

The factory head bolts hold up find up to around 450hp then they will stretch allowing cylinder gasses to escape past the head gaskets. That ecaped gas causes a "blow head gasket" which once it's been damage it can't be repair without removing the head and installing new gaskets. Head studs can be installed in the place of the head bolts one at a time (if the heads aren't disturbed) and increase the head clamping force substantially. Head studs don't stretch like the factory head bolts therefore can stand much more pressure. A great upgrade for high power. Head studs are recommended with stage 3 injectors or above.
