Valve spring NISSAN 350 Z 3.5 L - V-6 - DOHC 24 VALVE (VQ35) - 2003-2008

In all race engines there is harmonic high-frequency fatigue, which usually destroys the drive system if it is not controlled.

Properly designed valve springs ensure the required stability and reduce component wear.

Ferrea valve springs have been developed from high strength alloys, including premium grade chrome-silicon steel.

Our springs are heat treated and stress relieved, which radically increases the life span of the spring.

Our valve springs provide the stability needed for high-speed motors while minimizing load losses for today's aggressive valve combinations.
