SuperTech High Performance Valve Spring Kit, Toyota 2JZ-GTE

Outer Spring ID: 20 mm
Inner Spring ID: 20 mm

SuperTech dual interference springs are a popular choice for high-performance engines, including the Toyota 2JZ-GTE, for several reasons:

1. Improved Valve Control: Dual interference springs provide better control over the valves, reducing the likelihood of valve float at high RPMs. This is crucial for high-performance engines like the 2JZ, which are often pushed to their limits.

2. Enhanced Durability: These springs are designed to withstand higher pressures and temperatures, making them more durable than standard single springs. This durability is essential for the 2JZ engine, which is known for its ability to handle significant power increases.

3. Better Load Distribution: Dual springs distribute the load more evenly across the valve train components, reducing wear and tear. This even load distribution helps in maintaining the reliability of the 2JZ engine over time.

4. High-Quality Materials: Supertech uses high-quality materials and precise manufacturing processes to produce their springs. This ensures that they can handle the stresses of a high-performance environment, which is critical for the 2JZ engine, especially in turbocharged applications.

5. Compatibility: SuperTech dual interference springs are specifically designed to be compatible with the Toyota 2JZ engine, ensuring a perfect fit and optimal performance.

6. Increased Lift Capability: These springs can handle higher lift camshafts, allowing for more aggressive cam profiles. This is beneficial for 2JZ engines that are modified for higher performance, as it can lead to improved airflow and power output.

7. Reliability in High-Boost Applications: For 2JZ engines running high levels of boost, dual interference springs offer the reliability needed to prevent valve-related issues that can arise under extreme conditions.

 Installation requires the expertise of an engine builder.
