Main Stud Kit - Nissan VR38

The ARP Main Stud Kit for Nissan VR38 is a critical upgrade for builders and enthusiasts looking to enhance the performance and reliability of their twin-turbocharged engines. This kit addresses a common weakness in the factory fastening system—the main studs that secure the crankshaft to the engine block. It is suitable for various applications, including high-output street engines and competitive motorsports.

ARP studs are manufactured from premium alloy steel and feature custom-designed geometry optimized for the VR38's specific bolt pattern and clamping requirements. Unlike factory hardware, ARP studs deliver superior tensile strength and fatigue resistance, maintaining clamp load consistency across thermal cycling and repeated high-pressure events. The kit includes all necessary fasteners and hardware for a complete main stud conversion, engineered to ARP's strict tolerances.

This main stud kit is ideal for VR38 owners aiming for enhanced performance, whether for street use or competitive racing. Installation requires engine block removal and professional machine work, ensuring that the upgrade is executed correctly for optimal performance and reliability.
