The drive belt represents one of the most critical performance links in your Polaris vehicle—the link between the engine and high performance. The drive belt, also known as a CVT belt (continuously variable transmission belt), is a key component of snowmobile transmission systems. They are developed and tested on all our engines for all environments and conditions. Our snowmobile belts are designed, engineered and tested by Polaris Engineers and field test crews to ensure they deliver a perfect fit, high performance and excellent durability. Nothing else comes close.
