*KPMI® performance valve spring kits are modeled using cam pro昀椀le 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
di昀昀erent spring pressure option kits to choose from, these are the ultimate setup for any Polaris RZR/Ranger tuner.
