HKS valve springs are the performance versions specifically designed to be used with HKS camshafts.

HKS valve springs are the performance versions specifically designed to be used with HKS camshafts.

As valve train dynamics change from the use of high performance cam profiles and with greater lift, stiffer springs are often needed to optimize valve movement.

When changing to a high lift cam, the stock springs often can not match the increased valve train movement, therefore HKS has specifically engineered valve springs that match the characteristics of HKS camshafts.

A stringent shot peening and heat treatment process is applied to the HKS valve springs to provide durability and consistency in the spring rates over time.

Applications with high revving engines will especially benefit from the use of HKS valve springs, as the risk of valve-float is greatly reduced due to their specific design and construction.

This part usually ships 8 days after payment.
