Details

1. Compatible with High RPM Engines

As engine rpm rises, valves must open and close in a shorter time and so requires stronger Valve Springs in order to apply sufficient pressure.

2. Ensuring Close-Contact

When changing to high lift cams, proper contact between the valves and the cams can be lost which leads to valve float. HKS Valve spring use the highest quality materials, heat treatment and shot-peening to create a high durability spring with low inertia.
