ARP Custom Age 625+ Head Stud Kit Nissan VR38DETT GT-R (R35)

ARP Custom Age 625+ Head Stud Kit - Nissan VR38DETT - GT-R (R35)

This ARP head stud kit suits the VR38DETT engine in the Nissan GT-R R35. 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: Custom Age 625+ super-alloy rated at 260,000–280,000 psi tensile strength.
