Attitude Industries has spent a lot of time in the snow with Ski-Doo 800 ETEC. We have come up with clutching for both NA (naturally aspirated) and boosted turbo sleds. The Ski-Doo ETEC 800 Clutch Kits come with our custom helix, springs and everything needed to get your sled at the top of its game. The clutch kit offers lower belt temps, track speed gains and smoother engagement.
