ARP 2000 Head Stud Kit Subaru EJ20 / EJ25 DOHC WRX / STI (GC / GD / GE / GH / GR / GV / VA) / Forester (SF / SG / SH) / Liberty GT (BE / BH / BL / BP)

ARP 2000 Head Stud Kit - Subaru EJ20 / EJ25 DOHC - WRX / STI (GC / GD / GE / GH / GR / GV / VA) / Forester (SF / SG / SH) / Liberty GT (BE / BH / BL / BP)

This ARP head stud kit suits the EJ20 / EJ25 DOHC engine in the Subaru WRX / STI / Forester / Liberty GT. 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: ARP2000 rated at 220,000 psi tensile strength.

Before you order: DOHC EJ engines. For SOHC non-turbo EJ engines use ARP 260-4702.

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