EVP Billet Cylinder for Polaris RZR Pro XP, XPT/S, & Turbo R

If you want to make big power with your XP Turbo, Pro XP or Turbo R, one of the most important pieces to the puzzle are the cylinders. After more than a year of development and testing, EVP has the ultimate solution.  

The new EVP Polaris Billet Cylinder assembly is a direct replacement, stock bore design that’s been built to withstand the abuse high-boost power packages demand. Features that set this block apart from the cast stock unit include machined 6061 T6 billet construction with EVP-spec ductile iron liners, resulting in top-end stability and durability that the OEM cast aluminum cylinders cannot match. Additionally, this functional work of art features a closed top deck. All of these features keep the top end from “walking around” or shifting when under high boost and high cylinder pressure to provide a more stable sealing surface for improved head gasket life. These are a must for high-power packages!


Available with or without EVP BME Pistons, XR Series 625 Custom Aged Head Studs, and OEM gaskets. (NOTE: EVP BME Pistons are not compatible with Turbo R models.)
