I have these on my 2014 Ram 2500 with air suspension. I had Tembrens on my rear axle befor, but after about 8000k miles they were colapsed and right rear came apart due to bad roads, a heavy Truck camper, and the fact that they have no bottom piece , as in a guide or cup for the top mounted Tembrenair/rubber ''spring'' to fit into. So when suspension is ''unloaded'' and then comes back down [ as in going over bridge ,railroad tracks, or just our wonderful potholes, there is nothing to keep the tembren from slipping off the lower landing pad! These Sumo springs Have a bottom piece that the top fits into, and are much larger and rated for 4600lb [I think]..but work much better...less sway and, not a great ride empty, but better that the Tembrens when they were set up to do the job loaded. Too much $$$, but what isnt? Made in USA too!
