We have upgraded our Stage 2 and Stage 3 Legacy Kits! Now, our clutch kits are individually geared for specific types of riding and horsepower, from sand dunes to rocky ground. They provide the same great quality and can be used for all styles of riding, just with added improvement and more help on certain terrain! The performance is never sacrificed when you use our kits.
