Nissan Main Stud Kit - L24/L26/L28 6-Cylinder

The ARP Nissan Main Stud Kit for L24/L26/L28 6-cylinder engines delivers the reliability and durability demanded by serious engine builders and performance enthusiasts. Designed for 2-bolt main cap applications, this chromoly stud kit replaces factory bolts with premium fasteners engineered to handle elevated boost pressures, high RPM operation, and the demands of forced induction builds. Whether you're rebuilding a classic Z-series engine or maximizing power in a street performance application, quality main studs are non-negotiable insurance against catastrophic engine failure.

ARP main studs are manufactured from premium chromoly steel and finished in black oxide, providing superior tensile strength compared to OEM hardware while resisting corrosion during extended storage or harsh engine bay conditions. The 12-point nut design offers superior grip geometry and torque distribution, reducing the risk of fastener stripping during installation and ensuring consistent clamping load across all main caps. Each stud in this kit is precision-manufactured to exacting tolerances and individually inspected, delivering the concentricity and surface finish that professional engine builders depend on for reproducible results and long-term reliability under stress.

This Nissan Main Stud Kit is ideal for owners of L24, L26, and L28 6-cylinder engines planning serious modifications—turbocharging, supercharging, or high-compression naturally aspirated builds where stock fasteners cannot safely contain combustion loads. Installation requires basic mechanical skill and proper torque specifications (typically achieved with an ARP fastener installation kit and torque wrench), making this accessible to experienced DIY builders or professional machine shops alike. The black oxide finish and compact dimensions (4.3 x 2.45 x 8.8 inches, weighing 2.4 lbs) ensure easy handling during engine assembly while maintaining the aesthetic of a properly finished rebuild.
