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 \u003cp\u003ePart No. 65-726  (oro2u.com)\u003c\/p\u003e \u003cp\u003e  \u003c\/p\u003e \u003cp\u003e  \u003c\/p\u003e","brand":"ORO2U","offers":[{"title":"Default Title","offer_id":57196962775413,"sku":"65-726","price":135.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/5011\/6136\/files\/stock63482_1.jpg?v=1779064314","url":"https:\/\/www.smxoffroad.com\/es\/products\/valve-spring-kit-84-96-honda-xl-xr-r-l-rfvc-200-250-kibblewhite-30-30077-0-355-lift","provider":"SMXOFFROAD Ltd","version":"1.0","type":"link"}
