Question:
Hi, I have a 2019 gmc sierra 3500. I am currently using the double convoluted timbrens on it for towing my 5th wheel. Thinking of switching them out and giving the sumo springs a try. Timbrens still seem a little stiff. Thought maybe the sumo springs would give me a little better ride when towing. Pin weight of my 5th wheel is around 2600 pounds. Would these possibly work better?

Hey Steve, the SumoSprings kit part # SS46KJ is going to be more in the direction you are looking for as it will be smoother but if you're going to swap your Timbrens out I would actually recommend a different option. The Road Active Suspension kits as they will give you all of the support you are in need of but it actually will improve your loaded and unloaded ride quality as well as will improve handling loaded an unloaded. These are also adjustable too unlike the Timbrens and Sumosprings.
If you have a dually you would need the part # RAS3611-CHD or if you have a non-dually part # RAS3611-HD. This is for sure exactly what you are looking for.

Ok, what about the sumo springs rebel kits. I was also looking at them. My only concern was some people mentioned that there was no gap in between the two pieces when installed and your truck was unloaded so the ride was stiff when empty. My truck is a single rear wheel, standard bed
