Installed professionally in about 15 minutes on my 2020 Chevy Silverado SRT 6.2. We tow a travel trailer that weighs 7500 lbs loaded and had some porpoising issues on the miserable roads here in Nebraska. I also don't have the max towing leaf springs with the Z71 suspension (hindsight, but didn't want to wait 6 months for a truck!). All my weights are within vehicle limits. They didn't eliminate our issue but probably cut down the motion by 75%. Much better damping now. The rebound was terrible without these installed. They leave about an inch clearance unloaded so the day to day ride isn't compromised. The last tow was in a steady 25 mph crosswind with guts to 30 and there was virtually no side to side motion for the truck. I also have a weight distribution setup and the installation of these actually raised the rear of the truck 1/2 inch with the trailer attached. Our RV dealer liked the way it is setup. Call me pleased!

Easily Installed on 2018 Chevy 1/2 ton 4x4. Fits perfectly and helps to prevent the serious sagging suspension I had with the 32 ft RV hooked up to it. I'm personally not experiencing stiff or hard suspension with no load on it. Recommend this as a cheap alternative to air bags.

Although I haven’t really tested out the handling when trailering something, I just wanted to comment on the install. I have a 2020 Silverado. I did jack it up and removed the rear tires because I was installing wheel well covers also. Once you get the tire out of the way reaching the bump stop is no problem. I would say it took maybe 5 minutes each side. The product looks like it will work great for me. Can’t wait to haul a heavy load and test it.

Edit update: after a month of driving with sumo springs always touching with the spacer, the ride quality is now smoother. Seems like the sumo springs have worn in now and it feels like stock ride. No sag no roll everything perfect. Original post: My truck is leveled. It would sag in the rear when loaded a little bit and while accelerating loaded or unloaded it would sag. I installed this with the spacer on so it is touching all the time. It has fixed my issues no more sag or roll, loaded or unloaded. Even when accelerating the truck is leveled now. The ride feels the same without the extra bounce. Mind you the X31 rides stiffer than the regular ones so i don't notice it. Really happy with the purchase and best bang for your buck, we will see how it holds up in the winter in extreme cold here in Ontario, Canada. I have not seen any reviews for winter. I would highly recommend for leveled trucks or even if your not loaded all the time. It just rides better in my opinion

Bought a brand new silverado 1500 and the rear suspension is absolutely horrible for towing. I tow an 8000lb construction trailer 2-3 times a week. I have used air shocks and bags on previous vehicles, but was looking for a more simple option with less parts to fail. The sumosprings installed in 15 minutes and work awesome to stop the sag. I installed the spacers so they make contact all the time. I can't notice a difference in unloaded ride quality. Would definitely buy sumosprings again.
