What is the main benefit of using dual valve springs?

Dual valve springs offer improved stability and control over valve motion, especially at high engine speeds. They also provide a safety margin, as the second spring can help keep the valve seated if the primary spring fails.

What kind of engine modifications are these springs best suited for?

This dual valve spring kit is designed for engines with modified camshafts and those intended to operate at higher RPMs. They are a key component for building a high-performance engine.

What should I consider before installing this valve spring kit?

Before installation, ensure you have the proper tools for valve spring replacement. It's also important to confirm that your chosen camshafts are compatible with the increased spring pressure of this kit.

Product Details

If you're building a high-performance engine for your Subaru BRZ or Toyota 86 with the 2.0L FA20 engine, a strong set of valve springs is crucial. This dual valve spring kit from Supertech is designed to handle the increased demands of modified camshafts and higher RPMs. They help ensure the valves close reliably and quickly, preventing valve float which can lead to serious engine damage at higher speeds.

Supertech uses high-tensile spring wire, heat-treated and stress-relieved for consistent performance and durability. This kit includes dual springs, which means an inner and outer spring work together. This setup offers better stability and control over valve motion, especially at high engine speeds. The dual spring design also provides a safety margin; if one spring were to fail, the other can help keep the valve seated, potentially preventing catastrophic engine failure. This kit is a well-built component for anyone looking to push their FA20 engine beyond its stock capabilities.

When installing these, it's important to have the correct tools for valve spring compression and replacement. You'll also want to ensure your camshafts are compatible with the increased spring pressure. This kit is a key piece for anyone serious about engine tuning and performance upgrades on their BRZ or 86.
