Functional but not what I wanted
My Chevy Traverse has a rail system for the factory roof rack. I wanted better bars that would use the existing rail system. These do not. They attach to the window frame. The windows are closer together so although they work they are several feet closer together than the factory bars. My kayaks are 13.5 feet long so although I have gained bar strength I feel I have lost some stability. In fairness to Rhino Rack I was unable to find any racks that work with GMs funky rail system.
