HKS Valve Spring
HKS valve springs are designed for use with HKS camshafts for high revving engines reducing valve-float and providing greater durability.
HKS - Valve Spring
HKS - Valve Spring
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.
Features
1. Compatible with high rotations
As the engine speeds up, the time it takes to open and close the valves becomes shorter and the load required on the valve springs increases.
2. Ensuring close contact
When replacing with a high-lift cam, the stock valve spring may not have enough adhesion margin. HKS valve springs use the best materials, heat treatment, and shot peening to achieve both improved durability and reduced inertial weight.

About HKS
HKS was founded in October 1973 by Hiroyuki Hasegawa, a former Yamaha engineer, and Goichi Kitagawa, with start-up capital from Sigma Automotive; the name comes from Hasegawa, Kitagawa and Sigma. It began in a small shed at the foot of Mount Fuji, in Fujinomiya, Shizuoka, and is still based there.
In 1974 HKS built one of the first bolt-on turbo kits, for the Nissan L20 engine in the Skyline, raising output from 115 to 160 PS. Turbocharging made its name; today it also makes exhausts, springs, shocks and coilover suspension, and it marked its 50th anniversary in 2023.
