ARP 403-4302 Head Stud Kit

The ARP 403-4302 head stud kit delivers superior clamping force and reliability for high-performance engine builds. ARP head studs are engineered to provide more accurate and consistent torque loading compared to conventional head bolts, making them essential for engines running high boost, nitrous, or extreme compression ratios.

Key Features:

• Manufactured from premium 8740 chromoly steel for exceptional strength and durability
• Heat-treated to 200,000 PSI tensile strength for maximum clamping force
• Precision thread rolling process ensures superior fatigue resistance
• Includes black oxide finish for corrosion resistance
• Complete kit includes studs, hardened parallel-ground washers, and high-quality nuts
• ARP Ultra-Torque assembly lubricant included for accurate torque readings

ARP head studs eliminate the torsional load that occurs when using conventional head bolts, providing more even clamping force across the head gasket surface. This results in improved head gasket sealing and reduced chance of gasket failure in demanding applications. Each stud is centerless ground to ensure proper alignment and eliminate thread galling during installation.
