I just picked up JL with sky one touch roof. There is a hard rail the full side length of the jeep, front to back. The folds max out at 4-½”, so need that as minimun height clearance to the bottom of the rack bar. There are no hard ribs in the cloth roof, but would not want the cloth to keep rubbining the bottom of the rack. Suspect would void warranty. Have not yet found a roof rack with that clearance. Anyone else?I would not count on it clearing completely. Having never touched the Power Top I do not know if it is plyable or has rigid parts in it.
