ord Powerstroke 6.0L 625+ Head Stud Kit P/N 250-4205
ARP® has provided an extra measure of security in the form of extra-strong head studs manufactured from the firm’s proprietary Custom Age 625+® material that has a minimum rating of 260,000 psi tensile strength. They are engineered to provide the clamping force required to keep cylinder heads from lifting due to exceptionally high combustion pressures. This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness with complete resistance to atmospheric corrosion and oxidation.
ARP fasteners have been the standard in street and race performance since the late 1960’s and we trust their products on all our builds, from daily driver sleepers to drag strip monsters. We use these studs on all our higher horsepower street and racing builds and have never been let down. If you are pushing the 600 rwhp mark, this is definitely the way to go when it comes to keeping your heads in place.
