[20V Head Stud Kit]

ARP 20V 4AGE Head Stud Kit
ARP uses a premium grade 8740 alloy that is rated far superior to 'aircraft' quality. Each stud is precisely heat-treated to 200,000psi and centerless ground to make it as close to perfectly concentric as possible.

ARP studs are thread rolled after heat treat, which gives them about 1000% better fatigue strenth than studs threaded prior to heat treat. It costs a lot more to do it this way, but the results are worth the effort.

You won't find a better quality stud on the market from any other source.

Kit contains:

10 studs
10 parallel ground washers
10 compact 12 point nuts
