P1 – Chevrolet LS Head Stud Kit
Gen 3 & Gen 4 (2004 & Later) | Equal-Length Studs | 12-Point Nuts | S220 Series | Black Oxide Finish
PN# K003-H02S

The P1 Chevrolet LS Head Stud Kit is engineered for maximum clamping strength, consistency, and reliability in high-performance Gen 3 and Gen 4 LS engines (2004 and later). Featuring equal-length studs for streamlined installation and precise torque loading, this kit is designed to maintain head gasket integrity under extreme cylinder pressures, high boost, and sustained high-RPM operation.

Each stud is manufactured from P1’s advanced S220 Series alloy, delivering an exceptional 220,000 psi ultimate tensile strength. This USA-sourced steel is specifically chosen for its superior heat resistance and stability—critical for LS engines exposed to aggressive tuning, forced induction, or heavy competition use. The inherent thermal robustness of S220 steel allows these studs to maintain higher clamp load than competing hardware, ensuring a tighter, more secure head-to-block seal.

This material advantage helps prevent head lift, sealing failures, and gasket fatigue, even under extreme combustion pressure or turbocharger stress. A protective black oxide finish enhances corrosion resistance while giving each component a clean, professional appearance.

The kit includes precision-machined 12-point nuts and washers for consistent torque application, even load distribution, and improved long-term reliability.

Key Features:

  • Designed for GM LS Gen 3 & Gen 4 engines (2004+)

  • All studs are equal length for simplified installation and consistent torque distribution

  • Manufactured from S220 Series alloy with 220,000 psi ultimate tensile strength
