We've personally tested these studs to hold insane amounts of power. Talking over 700 HP to the crank and then tore down the engine just to see how they did.
Know what we found? Even after a year of running these at extreme levels, they came out like new.
ARP Head Studs are a complete part of your engine rebuilding breakfast. These are the 11mm head studs, and these are a great idea if you are rebuilding your engine back to stock specs, or if you are building your car to climb Mount Everest.
And here’s why:
These studs are constructed out of grade ARP2000 alloy that is rated far superior to “aircraft” quality. Then each stud is placed vertically In special racks and precisely heat-treated to 220,000 PSI. These studs are then rolled after the heat treatment, and this gives them about 1000% better fatigue resistance than your standard head studs.
Because of these reasons, many professional race teams of all motorsports genres trust ARP head studs to keep their motors together whether it be the drag strip, road course, or for a casual run to the grocery store.
