HKS 4A-GZE Strengthened Valve Spring Set
A stringent shot-peening and heat treatment process is applied to the HKS valve springs to provide durable and consistent spring rates over time. Applications with high revving engines will benefit from HKS valve springs, as the risk of valve-float and coil-bind is greatly reduced due to their specific design and construction.
