Product Details

The ARP 145-4005 Head Stud Kit is specifically engineered for World Products Hemi cylinder heads, providing superior clamping force and reliability for high-performance engine builds. ARP head studs are the preferred fastener choice for serious engine builders who demand maximum strength and consistent torque loading.

Key Features:

  • Custom-designed for World Products Hemi head applications
  • Manufactured from premium 8740 chromoly steel for exceptional tensile strength
  • Heat-treated to 200,000 PSI tensile strength rating
  • Precision-rolled threads after heat treatment to prevent fatigue failure
  • Includes hardened parallel-ground washers for even load distribution
  • ARP Ultra-Torque assembly lubricant included for accurate torque readings
  • Studs allow for more accurate and consistent clamping force than conventional bolts

ARP studs are designed to stretch within their elastic range, maintaining optimal head gasket compression even under extreme cylinder pressures. This kit provides the ultimate insurance against head gasket failure in naturally aspirated, supercharged, or turbocharged applications.
