ARP 400-2402 Cylinder Head Stud Kit

ARP cylinder head studs provide superior clamping force and reliability for high-performance engine builds. Engineered to replace factory head bolts, these studs allow for more precise and consistent torque loading, which helps maintain optimal head gasket sealing even under extreme cylinder pressures and temperatures.

Key Features:

• Manufactured from premium 8740 chrome moly steel for exceptional strength and durability
• Rated at 190,000 psi tensile strength, far exceeding OEM fastener specifications
• Parallel ground threads ensure accurate and repeatable torque readings
• Black oxide finish provides corrosion resistance and professional appearance
• Includes premium-grade hex nuts and hardened parallel-ground washers
• Thread engagement allows for multiple installation cycles without degradation

ARP head studs are the preferred choice for racing applications, forced induction setups, and any build where engine reliability is critical. The stud design eliminates the torsional stress created when torquing head bolts, resulting in more uniform clamping loads across the head gasket surface.
