Toyota 2JZ-GTE Valve Springs by SuperTech

Outer Spring ID: 20 mmInner 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 pre
