Since 1939, KPMI� has taken great pride in our ability to design innovative performance improvements for valvetrains. This innovative ability has never been more apparent than with the development of the �high tech lightweight racing valve spring kits �for the incredibly stressed and torturous environment in today's �high revving 4-stroke engines.
The challenge to engineer a valvetrain that would outperform OEM systems, that in some cases included titanium components, was not an easy one. This task would require the concentrated efforts of every member of KPMI�'s design team. It was apparent early on that an OEM style spring with a bit more pressure was not going to be the complete answer for these engines. Working together as a team enabled KPMI� to evolve with a �"unified system" �approach. In fact, these �innovative high performance lightweight valve spring kits, �would not only outperform factory parts, but outlive them as well.
Each KPMI� spring kit is designed for its specific application, taking into account several critical parameters including; cam profiles, harmonics, natural frequency of the springs, valvetrain mass, required pressure, wire stress, fatigue life, and engine rpm, just to name a few!
Today KPMI� proudly offers �complete high performance lightweight valve spring kits �for a host of applications.
