PN# K020-H01S

The P1 Toyota 2JZ Head Stud Kit (PN# K020-H01S) is engineered for extreme-performance 2JZ engines requiring maximum clamping strength, thermal stability, and long-term reliability. Designed to suit both OEM Toyota 2JZ blocks and Dart 2JZ blocks, this kit utilises 11mm thread geometry for superior block engagement—critical for high-boost, high-cylinder-pressure applications.

Each stud is manufactured from P1’s premium S220 Series alloy, delivering an outstanding 220,000 psi ultimate tensile strength. This advanced steel—sourced exclusively from USA-based mills—offers exceptional heat resistance and stability under the intense thermal cycling common in turbocharged and competition-grade 2JZ engines. The S220 material also enables significantly higher clamp load compared to competing fasteners, improving head-to-block sealing and reducing the risk of head lift under extreme boost levels.

The durable black oxide finish enhances corrosion resistance while maintaining a clean, professional appearance. Precision-machined 12-point nuts and hardened washers ensure balanced clamping, smooth torque application, and long-term head gasket integrity.

Whether the build is focused on drag racing, roll racing, high-power street performance, or full motorsport use, this kit delivers the fastening strength required to support substantial power levels with confidence.
