ARP 4A-GE/GZE 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
1 pack specially formulated Moly based assembly lubricant

NOTE: The stud closest to the exhaust cam gear may contact the distributor shaft. If this happens, the end of the distributor shaft must be ground down to prevent interference or catastrophic damage may result.
