Custom set of head studs for Mitsubishi 1.8L 4G93 and 2.0L 4G94 engines. This kit is assembled using ARP hardware only.
ARP's studs are made out of premium 8740 alloy, far superior than aircraft quality alloys. They are heat treated to 200,000 psi; and thread rolled after heat treat (which results in 1000% better fatigue strength than studs that are thread rolled prior to heat treat). These studs will make it much easier to re-assemble an engine ( especially a racing power plant which must be serviced frequently and quickly!) because the cylinder head and gasket are guaranteed a proper alignment. These ARP studs also provide a much more accurate and consistent torque loading. This is a custom set that is put together by ASP using only ARP fasteners.
