ARP Main Stud Kit - Mitsubishi 4G63 - Lancer Evolution IV–IX (CN9A / CP9A / CT9A)
This ARP main stud kit suits the 4G63 engine in the Mitsubishi Lancer Evolution IV–IX. It replaces the factory main cap bolts with studs and nuts, keeping the main caps clamped and located when rpm, boost and cylinder pressure go up.
Studs load the block threads more evenly than bolts and make it easier to line up the caps during assembly.
Material: 8740 chrome moly rated at 200,000 psi tensile strength.
See the Vehicle Fitment tab for the full list of vehicles.
