Hey Garry. To address the sagging in your 2019 Ram 1500's rear end, I recommend the SumoSprings Solo Custom Helper Springs item # SSR-307-47. These replace your factory bump stops and have a 1,500 lbs capacity. These are quite a bit better than the Timbren item # TDRTT1500, you were looking at. They have a progressive load control that only engages when weight is put on them. When you're not towing your trailer or carrying a heavy load in your truck bed you won't notice the SumoSprings item # SSR-307-47.

What kind of trailer do you have?
