Nissan Head Stud Kit 12pt.

The ARP Nissan Head Stud Kit 12pt. is a premium fastening solution engineered for Nissan 4-cylinder engines requiring reliable cylinder head clamping under extreme load conditions. Head studs are preferred over traditional bolts in high-performance and turbocharged applications where cylinder pressure, temperature cycling, and vibration demand superior holding power and repeatability. This kit delivers the clamping force consistency essential for maintaining proper gasket sealing and preventing head lift in demanding driving scenarios.

Constructed from chromoly steel and finished with black oxide coating, the Nissan Head Stud Kit 12pt. offers exceptional corrosion resistance and durability in engine bay environments. The 12-point nut design provides positive engagement and reduces the risk of fastener slippage during installation and operation, ensuring consistent preload across all cylinder head mounting points. Chromoly's superior strength-to-weight ratio compared to standard steel allows engineers to achieve higher clamping loads without risk of permanent deformation, critical for maintaining long-term seal integrity in modified or high-boost applications.

This kit is ideal for Nissan 4-cylinder engine builders, turbocharged conversions, and performance enthusiasts seeking to eliminate head gasket failures caused by insufficient fastener load retention. Installation requires proper torque sequence and tension measurement to realize the full benefit of the stud design. The black oxide finish protects against surface rust during storage and extended service life, making this kit a reliable choice for both street and track applications where engine reliability is non-negotiable.
