For sale ARP 256-4305 Head stud kit CA625+ for FORD Coyote 5.0L V8 2018-2020 in UAE, DubaiListing #102924

ARP studs are thread rolled after heat-treat, which gives them about 2000% (that’s twenty times) better fatigue strength than those studs that are threaded prior to heat-treat. It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort.
