ARP 203-4705 Head Studs for Toyota Supra (2020+)

  • Brand: ARP
  • Part Number: ARP-203-4705
  • Country of Manufacture: United States

ARP Pro Series head studs are built for high-load cylinder head clamping where consistent torque and repeatable service matter, especially on competition-focused engines.

Materials & Heat Treatment

  • Manufactured from premium grade 8740 alloy and proprietary ARP2000 alloy
  • Heat-treated in vertical racks for full heat penetration
  • Rated to 190,000 psi (8740) and 220,000 psi (ARP2000)

Why Studs Instead of Bolts

  • Easier cylinder head and gasket alignment during assembly
  • More accurate, consistent torqueloading versus bolts that twist during tightening
  • Studs are intended to be installed hand-tight so they load primarily on the vertical axis when torquing the nut
  • Undercut shorter studs can provide a load rate similar to longer standard-shank studs for more even clamping force

Manufacturing Notes

  • Manufactured to tight tolerances to help heads and gaskets align and seat cleanly
  • Highlights differences versus lower-quality studs that may be rolled from bar stock (often before heat-treat) and not centerless ground
