The nuts are also designed to be used with ARP's exclusive, high-strength, low-profile, washerless, copper-compressible, ring-type head gaskets (sold separately).

The studs are installed using ARP's unique, patented, stud installation tool, which provides even torque distribution and reduces the risk of damaging the engine block or studs during installation. The kit also includes ARP's exclusive, high-strength, stud installation nuts, which are used to secure the studs during the installation process.

In summary, the ARP 202-4701 Head Stud Kit is a must-have upgrade for anyone looking to maximize the performance and reliability of their Nissan 350Z or Infiniti G35 with the VQ35DE engine.
