For many years, Speedwerx 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 H5 Alloy springs in 2008. The H5 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 H5 Alloy springs have set the new standard in performance for trail, mountain, and racing applications! Kit is made by Speedwerx for Arctic Cat.
