HKS Valve Spring Kit Nissan Skyline GT-R

Valve spring performance is very important for valves to follow accurate cam profile.

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.

HKS put all their know-how knowledge into engine parts from the data they have acquired from the drag race, round race, time attack and drift race. The HKS team provide Engine tuning ranging from Camshafts, Pulleys, Pistons and Rods to Timing Belts, Pump Upgrades and even Head Gaskets.
