Supertech Toyota 2JZ Dual Valve Spring Kit

This kit includes a full set of Supertech dual valve springs and matching retainers specifically for the Toyota 2JZ engine. These are designed to handle the increased demands of performance camshafts and higher engine speeds, ensuring your valvetrain stays stable and reliable when you push the engine hard. If you're building a high-performance 2JZ, getting the valvetrain right is crucial for power and longevity.

Supertech uses high-tensile chrome-silicon wire for these springs, which offers excellent fatigue resistance and consistent performance over time. The dual spring design provides superior dampening and higher seat and open pressures compared to stock springs. This helps prevent valve float, especially at higher RPMs, and ensures the valves close securely. The included retainers are made from strong, lightweight materials to reduce overall valvetrain mass, which can help improve engine response. This kit is a well-built component for serious 2JZ engine builds where reliability and performance are key.

When installing these, it's important to follow the manufacturer's specifications for spring height and any required machining. This kit is intended for performance applications, so ensure your camshafts are compatible with the spring pressures and lift ratings. Proper installation is key to unlocking the full potential and durability of this valvetrain upgrade.
