Product Details

The ARP 202-4702 head stud kit is engineered specifically for the Nissan CA18DET engine found in 1989-1993 Nissan 180SX models. These premium head studs are essential for maintaining optimal cylinder head-to-block sealing in high-performance applications, especially when running high compression pistons, turbochargers, superchargers, or nitrous oxide systems.

Superior Materials and Manufacturing:

  • Constructed from premium grade 8740 chromoly steel alloy, exceeding aerospace quality standards
  • Heat-treated to 200,000 psi tensile strength for maximum clamping force
  • Centerless ground through approximately ten precision cuts to ensure near-perfect concentricity
  • Thread rolled after heat-treat for approximately 1000% better fatigue strength compared to pre-heat-treat threading
  • Features 12-point head design for improved torque application and reduced stripping risk

Performance Benefits:

  • Precision tolerances allow cylinder heads and gaskets to align perfectly during installation
  • Specially undercut shorter studs equalize stretch between studs for consistent clamping force
  • Compensates for head gasket compression to prevent blown gaskets
  • Provides superior clamping force compared to factory bolts for extreme performance applications

ARP head studs are the choice of professional Sport Compact and Import racers who demand reliability under extreme cylinder pressures. The kit includes all necessary studs, washers, and premium ARP assembly lubricant for proper installation.

Happy with the purchase! The lowest price and fast shipment.

Would not take my promo code....

I ordered a water pump from them and that Amazon was advertising as a Chrome pump. When I discovered it was not chrome, I asked to cancel the order which was prior to shipping notification. I was told by customer service it had already been sent and I would have to wait until the item was sent for a return to be processed. The return was sent back and all money was credited to my account as promised.
