The Fuji Racing Supreme valve springs are not a new concept and are industry proven to provide several key advantages over traditional spring designs. A major advantage of our conical springs is the damping and removal of valvetrain harmonics. Of the three industry designs, conical springs are the front runners in valvetrain harmonic stability. Utilizing a varying coil diameter as well as coil spacing, a conical spring acts as a natural harmonic damper in the transfer of valvetrain shock. This translates to less stress, less wear, and longer life of the included components. This level of protection is needed in todays engines being pushed to their physical and mechanical limits by aftermarket modifications. Every Fuji Racing Supreme spring offers a super finished surface treatment to go along with the patented, multi-step heat treatment process. The finished product is an extremely reliable, high-performance spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures.
