Nissan Main Stud Kit - VQ35 4-Bolt

The ARP Nissan Main Stud Kit for VQ35 4-Bolt engines delivers the reliability and precision that military and law enforcement professionals demand in high-stress applications. Designed specifically for the Nissan V6 platform, this chromoly main stud assembly replaces factory fasteners with premium-grade hardware engineered to withstand extreme loads and thermal cycling. Whether you're building a duty engine or performance platform, main studs are non-negotiable when reliability under pressure is mission-critical.

Constructed from chromoly steel and finished in black oxide, the ARP 202-5801 kit features 12-point nuts that ensure consistent clamping force and eliminate fastener slip during high-RPM operation or sustained load cycles. Chromoly material provides superior tensile strength compared to standard fasteners, critical when engine block stress increases from forced induction, high compression builds, or extended operational demands. The black oxide coating resists corrosion and oxidation, maintaining structural integrity in harsh environments. ARP's engineering guarantees precise torque specifications and load distribution across all four main bearing saddles, preventing block distortion and bearing failure.

This kit is essential for anyone rebuilding or reinforcing a VQ35 platform where engine durability is non-negotiable. Installation requires proper torque specifications and sequence protocols—ARP documentation provides exact procedures to achieve uniform clamping load. Mechanics, engine builders, and performance technicians working on Nissan V6 platforms will recognize that OEM fasteners lack the safety margin needed for modified or high-stress service. The compact kit dimensions (4.2 x 2.4 x 8.7 inches) ship complete with all studs and hardware needed for full main assembly replacement.
