We recently purchased a set of these from Etrailer for our 2013 Sante Fe we use to tow the 19. We always felt the rear was too soft (other owners agree) even without the boat so we added these to stiffen things up. Well, we have tried them now with the boat the can report great results with better control and stability and they actually reduced sag by over an inch with the boat hitched up. We have about 200-300lbs of tongue weight depending on load.
