ARP, the world leader in fastener technology, has just released a new Custom Age 625+® head stud kit for 1994-2007 Mitsubishi 2.0L (4G63) DOHC (EVO) applications.
Includes a set of ten Custom Age 625+® head studs, ten parallel ground washers, ten 8740 chrome moly steel 12 pt nuts and a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant.
All Custom Age 625+® studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated at 270,000 psi.
These fasteners deliver a 55% increase in tensile strength over the OEM Torque to Yield (TTY) head bolts.
