DÜHA Fas-Top® Rear Window Upgrade | Fits 2010-2018 RAM 2500 & 3500 Classic

The DÜHA Fas-Top® Window Upgrades offer the first technology that allows you to seamlessly switch the environment of your soft topper to match your immediate needs. Simply choose the Mesh Screen variant for maximum airflow or choose the Blackout Window variant for total privacy and security.

These upgrades feature the same industrial-grade zippers and reinforced stitching as the original Fas-Top® canvas. This is intentional because, although they are accessory windows, they are necessary to maintain the structural integrity and weather resistance of the topper during extended travel and highway speeds.

This modularity makes the DÜHA Fas-Top® Window Upgrades a must-have for any truck owner who uses their truck for multiple purposes. Great for camping trips where you need a bug-free cross-breeze, hunting trips with dogs, or for keeping gear hidden and secure when parked.
