Our SBB geometry is often imitated but certianly not duplicated. The ZRP spindles are the only Ski-doo spindles on the market that truly allow the ski to "pivot" instead of "swing". This translates to ultimate control even when hitting old tracks or other terrain features, giving unmatched rider confidence SUSPENSION SETUP While suspension setups will vary depdending on your specific application, we have found a good baseline for machines with a stock rear suspension is letting the limiter strap out to the next looser setting and adding about 1/2-3/4'' of preload to the front track shock. In some cases adding tension to the rear torsion spring may also be required. If you have any questions reguarding suspension setup or you are not running a factory rear suspension please call the shop. This comes with a set of 2 spindles, with bushings pre-installed, and is compatible with all factory hardware.
