Sumo spring helpers
Haven't towed anything with them yet, but they added stability to the factory ride, no sway in turns, when driving on rough roads ( I live in WV, I know what a rough road is ) they give you more control over your steering, because you have less rear bouncing and swaying.
Great springs
Love these springs!! Put these springs on my Ram 2500 before the purchase of Rugged Mountain 9RL truck camper. Loaded the camper in Boise Idaho and have driven through Idaho, , Oregon and Montana with no problems. Stops most of the sway from side to side. Love the fact that the springs are engaged before the trucks suspension' is. Got a long ways to go back to WV but springs are great and very easy to install.
