P1 – Nissan RB26 Main Stud Kit
12-Point Nuts | S220 Series | Black Oxide Finish
PN# K053-M01S

The P1 Nissan RB26 Main Stud Kit (PN# K053-M01S) is engineered to deliver maximum bottom-end stability, superior main cap retention, and long-term reliability for high-performance and competition-grade RB26 builds. Designed to handle extreme boost, elevated cylinder pressures, and high-RPM abuse, this stud kit provides the secure foundation required for serious power production.

Each stud is manufactured from P1’s advanced S220 Series alloy, offering an exceptional 220,000 psi ultimate tensile strength. This ultra-high-strength, USA-sourced steel provides outstanding resistance to stretch, thermal fatigue, and clamp-load loss—critical for RB26 engines running large turbochargers, forged internals, or high-horsepower tuning strategies. The enhanced clamp load capability of the S220 material helps prevent main cap walk and reduces crankshaft distortion, improving bearing life and overall bottom-end integrity.

A durable black oxide finish protects the hardware from corrosion while maintaining a clean, professional appearance. The included precision-machined 12-point nuts and hardened washers ensure even torque distribution for consistent and repeatable clamping.

Engine builders will appreciate the added security and stability this kit brings to the RB26 platform, making it ideal for drag racing, roll racing, circuit use, and high-boost street applications.
