HOT ROD SLED SHOP INC. SKI-DOO REV GEN4 850 ETEC 129" CLUTCH KIT. This is
the hardest, quickest accelerating, highest top mph drop-in clutch kit on the snow. Put lengths on a stock sled and lengths on your buddies clutch kit no matter what stage they have and it never quits pulling. One year in the making and worth the wait with hours of testing and tuning to get it done right. Wicked acceleration and on/off throttle backshift ---this is a really unbelievable difference in corner to corner acceleration. This kit includes our newest HRSS-PDM2 billet hardened and electroless nickel plated weights with drop-in rare earth nb52 magnets to adjust weight in 4 positions, H5 primary spring, H5 secondary spring and progressive helix. Our weights eliminate the oem Ski-doo clicker sytem and ramp completely with a more precise fit, superior weight system that is more efficient than the factory stuff. Our kits are very tuneable for various levels of riding style and horsepower and come with instructions for stock calibration, and setup instructions for Jaws Pipes, Bikeman Pipes, Dynoport pipes, and the new D&D pipe. Call if you want to chat about why we change to this style weight but the proof is in the performance. Check out the head to head reviews on dootalk.com and see why you need our clutch kit. New calibrations starting January 13, 2020 for the HRSS-PDM2 ramps and our 205-305 secondary spring for the hardest acceleration and speed WITH THE LOWEST BELT TEMPS yet.
