I have them on my 2017 Ram Eco Diesel. I did not install them for lift. My truck had a bit of roll with the trailer hooked up and after I installed the bags the roll pretty much went away. The bags are also good to alleviate bottoming out of the suspension when the bed is loaded. I do run my 1000# bags ~30# almost all of the time. I never expected, or wanted, any lift I just wanted to stiffen the suspension a bit.
Back in the day we used to install air shocks if we wanted an inch or three of lift.
