Crafted and built for racing snowmobiles used in extreme environments – such as natural or artificially-made tracks consisting of tight turns, banked corners, steep jumps and obstacles.

The Dayco Racing RPX™ Belt – the Official Belt of the CSRA for Snowcross Racing – provides maximum performance under the most extreme snowcross racing conditions. This belt features precisely pre-formed cogs that enable optimal flexibility, cooler running and extended belt life, along with high twist cords that demand intense strength under extreme tension. Not only is it the belt of choice for many professional and amateur drivers, the Dayco Racing RPX Belt is also the strongest aramid belt available on the market today. Its softer specialized polymer compound allows for quicker upshifts and downshifts and the fastest hole shot, helping racers stay ahead of the competition.
