Fuji Racing valve springs for your Subaru!
The Fuji Racing Supreme springs are not a completely new concept and have already been tried and tested for a long time. One of the most important advantages is the damping of the springs, which can prevent valve overlap.
By using a varying diameter and a different distance, the springs act as a natural, harmonic damper when transmitting valve shocks. This results in less force, less wear and a longer service life of the installed components.
This is of course an advantage for engines that are often pushed to their physical and mechanical limits through aftermarket modifications.
The Fuji Racing springs make it possible to run higher speeds and more aggressive camshaft profiles as well as higher boost pressure.
Complete with titanium mounts and spring seats.
As usual with Fuji Racing in perfect quality!
