These lower door inserts are the best sealing panels on the market, and they easily attach to your factory RZR 1000/Turbo 2 seat upper door panels. We designed these to create a nice tight seal when the door is closed, helping eliminate dust from coming in from around the door. And the bonus is….they are transparent! They are constructed of virtually indestructable 1/4″ tinted polycarbonate. This is the same UV protected tinted polycarbonate that we use for our tinted roofs and rear windows. The tint is actually in the material, not a film.
