Supertech valve spring kit For Nissan GTR VR38DETT SPRK-TS1015/GTR

Supertech valve spring kit Nissan GTR VR38DETT

With the help of Supertech valve springs & titanium valve spring retainers, higher RPM's can be run. It also eliminates valve flutter at high RPM's. At high RPM's, the rocker arms can break and the valve springs can jam. This can lead to engine damage! The Supertech valve springs have an extra adjusted spring rate.

Advantages:

The valve train becomes lighter thanks to the titanium valve spring retainers
The motor revs up faster
Higher motor RPM's can be run
The valve train becomes more stable during power increases
We recommend our Supertech black nitrided intake valves and Inconel exhaust valves with all Supertech valve spring kits.
