What is the primary benefit of using a dual valve spring kit?

A dual valve spring kit offers improved stability and control over valve motion, especially at higher engine speeds. This helps prevent valve float, which is crucial for maintaining engine integrity during spirited driving or performance modifications.

What material is used for these valve springs?

These valve springs are constructed from high-tensile chrome silicon wire. This material is chosen for its strength and its ability to withstand the repeated stress and heat cycles experienced within an engine.

What other engine modifications might require this type of valve spring upgrade?

This dual spring kit is particularly beneficial when increasing engine RPM limits or installing performance camshafts with more aggressive profiles. These modifications place greater demands on the valve train than stock springs can typically handle.

Product Details

The Ferrea KT4022 dual spring kit is built with high-tensile chrome silicon wire, a material chosen for its strength and ability to withstand repeated stress cycles. This kit is specifically designed for the 2012-2015 Scion FR-S and Subaru BRZ, addressing the needs of engines that are pushed harder, whether for track use or spirited street driving. Upgrading your valve springs is a critical step when you're looking to increase engine RPMs or make significant changes to the camshaft profile, as the stock springs may not be able to keep up with the demands.

This dual spring design offers improved stability at higher engine speeds. The inner and outer springs work together to control valve motion more precisely, reducing the risk of valve float, which can lead to serious engine damage. Ferrea is known for its well-built engine components, and this spring kit is no exception. They are manufactured to tight tolerances to ensure consistent performance and reliability. When you're rebuilding the top end of your engine or installing performance camshafts, a robust valve spring setup like this is essential for harnessing the full potential of your modifications and ensuring the longevity of your engine.

This kit includes the necessary dual valve springs to replace the stock components. It's important to consult the manufacturer's installation instructions for specific details regarding installation procedures, tool requirements, and any other components that may need to be addressed during the upgrade process. Proper installation is key to achieving the performance benefits and reliability this kit offers.
