MCB 570/900/1000 PROSTAR engines Shim Conversion Kit

If you are tired of having to purchase a new, different size, complete cam bucket every time you need to shim your Polaris 900 1000 and Turbo , MCB has the solution. Our Shim conversion kit lets you utilize the inexpensive 9.48 individual valve shims once you change over to our custom retainers and coated buckets/tappets. This kit is designed to be used with stock valve springs and even your OEM locks fit perfectly. The kit includes eight (or 4 if 570) HD cam tappets/Buckets that are Carbon RST coated for a massive increase in life and friction reduction. Also included are eight (or 4 if 570) Tool steel valve spring retainers machined for both OEM springs as well as HD aftermarket ones. These are Black Oxide coated to aid in cooling and reduce surface wear. All components are engineered to work together saving you the hassle and expense of sourcing individual parts.
