Trying to decide between the two. Right now, I can get by without either but figured I would add either of the two for increased stability. My sag is not that bad, an extra half inch would be nice though. My sense is that the main difference between the two is the Sumo Springs appear to have more "travel"? Meaning they can compress farther than the Timbrens. I feel like in my situation the Sumo Springs might work better since I don't need a lot of support, just a little, and the extra travel might equate to a little better ride loaded since the Sumo Springs can compress more. I could be totally wrong about all this. So what is everyones opinion of the SumoSpring vs Timbrens??

I've been running the Sumo Springs for a few years now and I really like them. They do not engage when light loaded and when I load the TC, they do exactly what I need them to do ... provide extra suspension support and cut down on sway. No maintenance was also a big attraction for me. I'm very happy with the Sumo Springs. I got the 2,800 lb. variety. If you search my posts, there is a full write-up.

We have had Sumo springs on our F350 for three years and around 30,000 miles. I chose them over Timbrens for the same reasons, more travel and a bit softer compression. I have been very happy with them.

I have been using Timbrens since 2006, and chose them over the Sumos because of the rubber construction vs the poly construction of the Sumos. I used the double convolute on my 2005 1 ton and then tried the single convolute on my 2015 dually.Didn’t like the single convolute so I talked with Timbrens, after looking at different double convolute specs, and they sent me a set double convolute that I felt would ride softer and allow the truck to set level at full load. I am very pleased with my setup and you can’t beat Timbrens for their great customer service.

Timbrens work great for me too. I agree on their after the sale service.

I added the heavy duty Timbrens after the first year with my camper to help when pulling my trailer. No weird proposing, sway, or maintenance with them like some have with air bags.
