Product Details

The ARP 190-4205 head stud kit is engineered specifically for Pontiac Ram Air 5 engines, providing superior cylinder head clamping force compared to OEM bolts. This kit includes 12-point nuts for enhanced torque application and reduced risk of fastener damage during installation.

Premium Material and Manufacturing:

  • Constructed from premium grade 8740 chromoly steel alloy, heat-treated to 200,000 psi tensile strength
  • Thread rolled after heat-treat for approximately 1000% better fatigue strength than pre-heat-treat threaded fasteners
  • Centerless ground through multiple precision cuts to ensure exceptional concentricity and straightness
  • Allows cylinder heads and gaskets to align perfectly during installation

Performance Benefits:

  • Critical upgrade for high-compression builds and engines using power adders like turbochargers, superchargers, or nitrous oxide
  • Specially undercut shorter studs equalize stretch characteristics for more consistent clamping force
  • Compensates for head gasket compression to prevent blown gaskets
  • Ensures optimal head-to-block sealing under extreme cylinder pressures

ARP head studs are the preferred choice of professional engine builders and racers who demand reliable performance under the most demanding conditions. Each kit includes studs, washers, and 12-point nuts with assembly lubricant.
