For good reason that virtually every top professional engine builder relies on ARP head studs for their all-out competition power plants. Simply stated, theres not a better stud setup on the market today. ARP uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi pounds per square inch. ARP studs are thread rolled after heat-treat, which gives them about 1000% (thats ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). You wont find a better quality stud on the market from any other source.
