What is the main benefit of using dual valve springs?

Dual valve springs provide better control and stability for the valvetrain, especially at higher engine speeds. This setup helps prevent valve float, which is crucial for maintaining engine performance and preventing damage in modified or high-RPM applications.

Do I need special tools to install this valve spring kit?

Yes, installing valve springs typically requires specialized tools such as a valve spring compressor. You will also need a method to keep the valves from falling into the cylinder during installation. Always refer to the manufacturer's installation instructions for specific tool requirements.

What other components might I need when installing these springs?

While this kit includes the dual valve springs, you may need to consider compatible retainers, valve seals, and potentially upgraded camshafts depending on your engine build. It's recommended to consult your engine build guide or a professional mechanic to ensure all necessary parts are accounted for.

Product Details

This is the Supertech 16V Dual Valve Spring Kit for Subaru WRX and STi models. If you're building a high-performance engine or pushing your Subaru's engine beyond stock limits, especially with a more aggressive camshaft, these dual valve springs are a critical component to ensure your valvetrain stays stable at higher RPMs. They help prevent valve float, which can lead to serious engine damage.

Supertech is known for making well-built valvetrain components, and this kit is no exception. It includes dual springs, which means you get an inner and outer spring for each valve. This setup offers better control and stability compared to single springs, especially under demanding conditions. The springs are made from strong materials designed to handle the increased stress and higher operating speeds you'll encounter in a modified engine. This kit is designed to work with the stock retainers and seats in many applications, simplifying installation, but it's always a good idea to check compatibility with your specific cylinder head setup.

When installing a performance valve spring kit like this, it's important to have the right tools and knowledge. You'll typically need a valve spring compressor and a way to keep the valves from falling into the cylinder. This kit is a solid option for anyone looking to upgrade their Subaru's valvetrain for increased reliability and performance. Make sure to consult your engine build guide or a trusted mechanic to confirm all necessary components and procedures for your specific application.
