ARP - Engine Head Stud Bolt Kit for Nissan Skyline GTR RB26DETT

ARP 202-4207 Engine Head Studs Bolts Kit Skyline GTR RB26DETT Replace your stock head bolts with ARP heavy duty head studs. The stud design helps the head and the block equalize the pressure better thereby creating a much more even and consistent seal. It is recommended to replace the head studs/bolts with a new set if the head bolts are ever loosened due to metal fatique. Reusing an old and possibly warped or stretched head bolts/studs will sacrifice the seal between the head and block and may cause head gasket leak. This is a great an easy upgrade when doing an engine rebuild or building a race motor. This kit comes with: studs, washers, nuts, and assembly lube.
