ARP Nissan GTR RB26DETT ARP2000 Head Stud Kit

Ensure maximum cylinder head sealing and prevent catastrophic head gasket failure in your high-performance Nissan RB26DETT engine with this premium ARP Head Stud Kit. Specifically engineered for the legendary Skyline GT-R platform, these studs are a mandatory upgrade for engines running increased boost levels, large turbochargers, or high-octane fuels. By providing significantly higher clamping force than factory head bolts, this kit eliminates cylinder head “lifting” and protects the engine block threads under extreme combustion pressures.

Key Features

• ARP2000 Alloy: Manufactured from proprietary ARP2000 material, which is capable of achieving a higher clamp load than standard 8740 chrome moly, making it ideal for high-boost RB26 applications.
• Superior Strength: Heat-treated to a 220,000 psi tensile strength—providing a massive safety margin over OEM hardware and standard performance fasteners.
• Consistent Preload: Studs allow for more accurate torque readings because the fastener does not twist during the tightening process, ensuring uniform pressure across the entire head gasket surface.
• Enhanced Fatigue Life: Threads are rolled after the heat-treating process, providing vastly superior fatigue strength and resistance to thread stripping compared to standard cut-thread fasteners.
• 12-Point Nut Design: Features compact 12-point nuts that provide superior tool engagement and easily clear the valvetrain components in the RB26’s twin-cam cylinder head.
