This Sand Dune Clutch Kit is designed and tested specifically for sand dune applications. We offer different kits for stock and paddle tires, and will help reduce belt slip and clutch heat. You will get better low end power and torque on your machine, and a quicker backshift which results in a crisper throttle response. This kit will also help hold peak power RPM when dune riding and climbing hills!
