Straightline Performance Polaris RZR XP 1000 Belt-Aid Kit

Straightline Performance Belt-Aid is a model-specific CVT cooling kit for Polaris RZR XP 1000, RZR XP 1000 Turbo, and RZR XP Pro 1000 Turbo side-by-sides, fitting both two- and four-seat configurations. It reads ECU data such as vehicle speed, throttle position, and fuel consumption to decide when to spray atomized coolant into the CVT system, so belt temperatures are managed without the driver having to think about it.

Developed in desert and short-course UTV racing, where CVT temperatures can climb rapidly over long races and short high-heat events, the kit typically drops peak temperatures by more than 70 degrees Fahrenheit once installed. The kit ships with all necessary hardware; you simply choose the coolant bottle that suits your application and install it.
