The P1 Toyota 2JZ Head Stud Kit is engineered to deliver uncompromising clamping force and long-term reliability for high-performance 2JZ builds. Designed to suit OEM Toyota blocks as well as Dart 2JZ blocks, this kit utilises 11mm thread geometry for superior thread engagement and strength under extreme cylinder pressures.

Manufactured from P1’s premium E190 Series alloy, these studs provide exceptional tensile strength and fatigue resistance, making them ideal for high-boost, high-RPM and competition-level engines. Each component features a durable black oxide finish, providing enhanced corrosion resistance and a clean, professional presentation during assembly.

Included are precision-machined 12-point nuts and washers to ensure consistent torque, even load distribution, and repeatable head sealing—critical for engines using upgraded turbo systems, aftermarket gasket solutions, or elevated combustion pressures.
