What is the main benefit of using dual valve springs?

Dual valve springs offer improved stability and control over the valve train, especially at higher engine speeds. This setup helps prevent valve float, which is when the valve doesn't close properly, and can lead to engine damage.

What material are the Supertech valve springs made from?

These valve springs are constructed from high-tensile wire. This strong material is chosen for its ability to resist fatigue and maintain consistent tension over time, ensuring reliable performance.

What should I pay attention to during installation?

It's important to follow the manufacturer's specific installation instructions closely. Pay particular attention to details like spring seat pressures and installed heights, as these are critical for achieving the correct performance and ensuring the longevity of the engine components.

Product Details

Supertech is known for making well-built engine components, and this dual valve spring kit for the Mitsubishi 420A engine is a prime example. If you're rebuilding the top end of your 420A, whether for performance or to refresh worn-out parts, a strong valve spring setup is crucial for keeping everything in sync at higher RPMs. This kit is designed to handle the demands of modified engines.

This kit includes dual springs, which means you get an inner and outer spring for each valve. This setup offers better stability and control over the valve train, especially as engine speeds increase. Dual springs help prevent valve float, that moment when the spring can't close the valve fast enough, which can lead to serious engine damage. The springs are made from high-tensile wire, a strong material that resists fatigue and maintains its tension over time, ensuring consistent performance. This is important for engines that see a lot of use or are pushed harder than stock.

When you're installing these, pay close attention to the manufacturer's instructions regarding spring seat pressures and installed heights. Getting these details right is key to achieving the intended performance and longevity. This kit is a solid choice for anyone looking to build a reliable and capable Mitsubishi 420A engine.
