ARP 208-4307 Head Stud Kit for Honda Engine - H23A

The ARP 208-4307 head stud kit is engineered specifically for Honda Prelude H23A engines, delivering superior cylinder head-to-block sealing for high-performance and forced induction applications. These premium head studs are essential for engines running high compression pistons, turbochargers, superchargers, or nitrous oxide systems.

Premium Construction and Manufacturing:

• Manufactured from premium grade 8740 chromoly steel alloy, rated superior to aircraft quality materials
• Precision heat-treated to 200,000 psi tensile strength for exceptional durability
• Centerless ground through approximately ten precision cuts for near-perfect concentricity and straightness
• Thread rolled after heat-treat for 1000% better fatigue strength compared to pre-heat-treat threading
• Specially undercut design on shorter studs equalizes stretch for consistent clamping force

Performance Benefits:

• Exacting tolerances allow gaskets and cylinder heads to glide into perfect alignment during installation
• Consistent clamping force compensates for head gasket compression
• Prevents blown head gaskets and ensures optimum sealing under extreme conditions
• Superior strength and reliability for racing and high-performance street applications

ARP head studs are the preferred choice among Sport Compact and Import racers who demand the highest level of quality and performance from their engine fasteners.
