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.
