8639-358 Arctic Cat Hypershift Clutch Kit - 0-5000-ft - 2021 ZR 6000

For many years, had worked very hard to set the bar in performance clutch kits utilizing titanium springs. The springs and clutch kits worked perfectly but the price was hard to swallow due to the rising cost of titanium. After two years of rigorous testing, we introduced the Alloy springs in 2008. The Alloy springs have a 30,000 to 40,000 psi higher tensile strength compared to standard chrome silicon wire springs and they won’t lose rate over time, so you can get the durability and consistent performance of a titanium spring at a fraction of the cost. The Alloy springs have set the new standard in performance for trail, mountain, and racing applications! Kit is made by for Arctic Cat.
