Replace those noisy and leak prone soft upper doors with the new Rugged Ridge Hard Door Sliders. Constructed of durable steel, uv treated plastic, tough vinyl soft top material and DOT approved glass, these upper door sliders are designed to last. Each Upper door is designed to securely fit into your factory hard lower half doors creating a weather tight seal while looking like a soft upper door- provides a quiet ride and great looks. The DOT approved locking glass windows are "dual sliders" for maximum ventilation and easy access to toll booths.
