I have that rack on my JKU with dual tops. This past summer I had the hard top on all summer because I use the rack with my four kayaks. The reason the soft top is not on is because when taking the soft top down, it folds back. The rack has a tilt back feature to allow the soft top to fold back. When I put the rack into tilt back position on the supplied metal supports, the top would not clear the rack to open. I haven't tried it since. I can tell you that it is such a PITA to deal with the rack to tilt it back; even if I could lower the top, I don't know if it is worth it to do it. The rack is built like a brick shlt house. I love using it to put my kayaks up there. But if you purchased it for its versatility with a soft top I'd say you got it for the wrong reason. Right now I'm considering making a device to make it easy to lift the rack off of the jeep. I'd rather be running the soft top without the rack so I can use the features of the soft top than run it with the rack on. The rack is awesomely solidly built but just not versatile as they would lead you to believe in the advertisements. I think you'll have to sort this out on your decision to purchase a soft top.
