Cold rides and muddy trails are the point of this upper door kit, which closes the open sides of a two-seat side by side against rain, wind, snow, branches and flying debris. Panels are cut from tear-resistant Pvc sized 51.6 by 25.0 inches, a fitted shape matched to Maverick X3 two-seat models from 2017 through 2025 so the fabric pulls tight instead of flapping at speed. High-tension nylon zippers run under protective fabric flaps, keeping water and mud out of the teeth and stopping the snags that end the life of an exposed zipper. Roll-up window sections open for airflow on a warm afternoon and close down for a cold morning, while reflective strips add visibility to other traffic after dark. Clear Pvc panels preserve a wide sight line to the trail and pre-cut slots clear most side mirrors without removing them. Straps and hook-and-loop fasteners hold the 4.1 pound kit in place with no drilling or tools required.
