This spring kit has been developed to control the valvetrain in the high manifold pressures and temperatures of turbocharged Arctic Cat 1056cc Sleds.
Our Arctic Cat kits have been raced and tested under the most brutal conditions by racers across the country.
The KPMI® spring kit includes dual springs designed with attention paid to natural frequencies to avoid cam harmonics, FEA designed lightweight titanium retainers to reduce reciprocating mass, and hardened steel bases to keep the spring where it belongs. This kit is capable of handling high RPM, up to 35PSI of boost, and up to .380 valve lift!
Coupling this kit with KPMI® Black Diamond Valves and C630 bronze guides has proven to be a race winning combination. Custom One Piece Forged Tensilite® Titanium valves and KPMI® High Performance Shim in tappets conversion systems are also available.
