  • Hot Cams Valve Shim Kit

    Hot Cams Valve Shim Kit

    Derick in MI

    Good shims - poor shipping

    I ordered one case of shims and received two cases taped together. When I removed the tape it removed the shim size numbers from the back of the case. I am still confused as to why I received two cases. Other than that, I would give 5 stars for the shim quality.

    This Kit is worth the money!

    The exhaust on this kit is perfect. Increase exhaust flow and sounds throatier, its not annoying loud. If anything this is the upgrade to get. I am excited to see how the cams are going to do once installed. Amazing how much power this kit increases the RzR. I love it!

    Stephen in CA


    Works great it fits the valves perfect. I used this with the Prox stainless steel intake valve kit. This item is a single seal, you must order one for each valve being replaced or repaired.

    Great quality

    This is a nice kit. Has every size I will ever need. All the new shims were very consistent with the measurements on the shim. They seem to hold up well with no complaints
