ARP Head Stud Kit Mitsubishi 4G63 Lancer Evolution IV–IX (CN9A / CP9A / CT9A)

ARP Head Stud Kit - Mitsubishi 4G63 - Lancer Evolution IV–IX (CN9A / CP9A / CT9A) - M11

This ARP head stud kit suits the 4G63 (M11, 1994–on) engine in the Mitsubishi Lancer Evolution IV–IX. It swaps the factory head bolts for studs, nuts and washers. The studs are wound into the block by hand and the head is clamped by torquing the nuts, which gives more even, repeatable clamping than factory stretch bolts and saves wear on the block threads each time the head comes off.

More clamping load helps the head gasket seal against high cylinder pressure, which is why head studs are one of the first parts fitted to a boosted or high-compression build.

Material: 8740 chrome moly rated at 200,000 psi tensile strength.

Before you order: Suits the M11 head-bolt 4G63 ('94 on). Not for earlier M10 engines.

See the Vehicle Fitment tab for the full list of vehicles.

Note: Installation by a professional is recommended.
