Jeep does it stand for Just Empty Every Pocket? Well we here at Roof Rack & Box just don’t know but what we do know is that you can fit a set of Yakima Whispbar S25W roof bars on a K624 fitting kit (or S17W + K624)to your Grand Cherokee and instantly add the ability to carry long things. Yes such long things might include skis and snowboards or a SUP maybe even a ladder, you never know because the sky is the limit and with roof bars not only will your stuff be closer to the sky but you’ll also have a higher limit. (no actual limits will be increased). Another Grand Cherokee mounted Tiber basket TIB-90305.
