On a Wrangler JK, the door surrounds help fill the gap between your Jeep's doors and the sports bar roof rails. If you don't have them or they aren't in good condition, there is no way to seal your interior from the elements. Rampage JK Door Surrounds are a direct replacement for your worn or damaged originals and will work with OE and most aftermarket soft tops. Installation is easy using the factory mounting locations with no tools needed.
