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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eEach 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!\u003c\/p\u003e\u003cp\u003eToday KPMI® proudly offers complete high performance lightweight valve spring kits for a host of applications.\u003c\/p\u003e\u003cul style=\"box-sizing: inherit; list-style-position: inside; padding-left: 2rem;\"\u003e\n\u003cli style=\"box-sizing: inherit; list-style: inherit;\"\u003e1) These spring kits are compatible with the OEM tappet lash adjustment system and the KPMI® shim conversion tappets.\u003c\/li\u003e\n\u003cli style=\"box-sizing: inherit; list-style: inherit; margin-bottom: 0px;\"\u003e2)The seals included in these kits are intended for use with OEM guides.
