ARP Head studs
Todays engines often use high comp pistons or high boost which demands optimum sealing between the cylinder head and the block.
ARP uses 8740 chrome moly steel that is rated far superior to "aircraft" quality. Each stud is precisely heat-treated to a nominal tensile strength of 14.000km/cm². The stud is then given ten slight cuts which results in an exceptionally straight part. Lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form, usually prior to heat-treatment.
ARP studs are thread rolled after heat-treat, which gives them about 1000% better fatigue strength than those studs that are threaded prior to heat-treatment.
The Undercut studs equalizes the stretch, which makes for a more consistent clamping force. These studs are only avaliable for selected applications. |
