DESCRIPTION

EVP engineers designed and manufactured the ultimate game-changer when it comes to lowering compression for the RZR Pro R. Stock compression ratio on the N/A ProStar 2.0L engine runs high at 12.5:1, which is inadequate for any turbo upgrade/engine build running high boost and big horsepower. The new EVP Head Shim Kit for Pro R's lowers compression to 10.8:1 to help reduce air/fuel temperatures and thus prevent detonation as well as pre-ignition.

  • Lowers stock compression ratio from 12.5:1 to 10.8:1 to better support high boost/horsepower applications
  • Multi-layer steel construction designed for optimal sealing
  • Full metal construction leaves no residue behind
  • Extremely durable under high temperatures and boost pressure
  • Kit includes RZR Pro R Shimmed head Gasket, Manifold Spacer and Valve Spacer
