  • These spring kits are compatible with the OEM tappet lash adjustment system and the KPMI® shim conversion tappets.
  • KPMI® performance valve spring kits are modeled using cam profile and simulation softwares. By utilizing FEA software, it was possible to take advantage of the increased strength and wear resistance of a heat treated steel retainer, while reducing its mass to within grams of a comparable titanium retainer. With two different spring pressure option kits to choose from, these are the ultimate setup for any Polaris RZR/Ranger tuner.
  • The seals included in these kits are intended for use with OEM guides. Please use KPMI® P/N 71016-8 when installing KPMI® guides. Some early 2013 models came from the OEM with guides that included a seal detail. These guides require the use of KPMI® seal P/N 71015-8.
