Mopar Head Stud Kit - 12pt. 96-06 Viper

The ARP Mopar Head Stud Kit - 12pt. 96-06 Viper (MPN 247-4201) is a premium fastening solution engineered for serious Viper owners and high-performance Dodge V10 engine builders. Head studs replace factory bolts to provide superior clamping force and repeatability under extreme combustion pressures and thermal cycling. This kit exists to prevent head lift, gasket failure, and catastrophic engine damage in vehicles running stock boost, forced induction, or high-rpm applications where factory hardware reaches its limits.

Built from premium chromoly steel and finished in protective black oxide coating, this head stud kit delivers measurable advantages over original equipment. The 12-point nut design ensures positive engagement and reduces the risk of fastener rounding—critical when working on high-dollar engine builds. ARP's proven methodology optimizes stud diameter, length, and preload specifications for the Viper's legendary V10 architecture, allowing predictable torque values and consistent clamping pressure across all eight cylinders. The chromoly material exhibits superior fatigue resistance compared to grade-8 bolts, translating to extended service life and reliability during sustained high-load operation.

This kit is essential for 1996–2006 Viper owners preparing for turbocharging, supercharging, or nitrous oxide use, as well as engine builders restoring or modifying Mopar V10 blocks. Professional machine shops and enthusiasts alike rely on ARP studs to ensure repeatable, leak-free cylinder head sealing. Installation requires proper torque sequence and ARP-recommended preload specifications; consult your engine manual or machine shop for exact procedures. Compatible with standard Dodge Viper 8.0L and 8.3L V10 engines across the 96–06 production window.
