ARP - The world leader in fastener technology has released a new Custom Age 625+ head stud kit for 2008 and later Mitsubishi Lancer Evolution X (10) 4B11T Turbo applications.
207-4207 kit includes a set of ten Custom Age 625+ head studs, ten parallel ground washers, ten 8740 chrome moly steel 12 point nuts and 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant.
All Custom-Age 625+ studs are centreless ground, heat treated prior to thread rolling and machining, and are nominally rated at 270,000PSI. These fasteners deliver a 55% increase in tensile strength over the OEM Torque To Yield (TTY) head bolts.
