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.

I really like the design with the LinQ ready sides. I purchased the additional LinQ latches and this thing is rock solid. I also purchased the PRP bag to go on top. This is by far the best way to carry tools, parts, etc. while on my multi day rides or just going out for the day. With my OEM tire rack, I can see out the rear view mirror! Oh, and customer service is excellent.

Beautiful craftsmanship as always.
