Found exclusively on the 2017 Arctic Cat Thundercat models is the new TEAM Rapid Response II drive clutch. The TEAM Rapid Response II features an industry exclusive auto-adjusting belt tension design that delivers consistent performance without manual adjustments, always maintaining the proper sheave-to-belt side clearance. It also features a 12.5 percent lower effective starting ratio (while maintaining the top ratio) for smoother engagement and reduced belt wear at drive-away speed, with more evenly distributed force for lower belt pressure.
