SuperSprings Set of Rear SumoSprings fits 2019-2025 Silverado/Sierra 1500 (New Body Style Only) | 1000 lb Capacity at 50% Compression | Simple Installation

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!

I had the Timbren bump stops on my previous truck and they worked great when towing but when not towing I was very disappointed with the ride of my truck, felt like my half ton was one ton truck. I was skeptical about the Sumo Springs but I decided to give them a try and they worked great!! When the truck is empty or not towing the ride quality did not change one bit. Had my first chance to tow with them this weekend. Towed an enclosed trailer with a full size old heavy car. Pushed the back down a little as expected but still had plenty of suspension movement with the Sumo's. Gave a nice steady drive without bottoming out the truck's suspension. Very happy with the product A+++

Very easy to Install. took me about 45 min total to install on my GMC . Made a big improvement driving my Travel trailer to Florida this past winter.

Worked perfect for my 2021 Trailboss Silverado 1500. Did an installation video on YouTube too if you want to see. Towed my trailer with quad and was literally perfect. No bumper sag and avoided all unnecessary bouncing.

Second time I've used Sumo Springs on a Silverado. First time on a 2021, 2500HD with a 2500 pound camper onboard all the time. The Sumo Springs were compressed about 3/4" with the vehicle loaded and provided leveling, roll stability and did not affect the ride quality. This time I installed them on a 2022, 1500 Silverado with 300 pounds of load in the bed all the time. The Sumo springs only have about 1/2" of free spring travel before coming into contact. With less vehicle spring travel before coming into contact, they provide a firmer ride without a heavy load (not really desired but tolerable). I have not towed our trailer since this install but expect less equalizer bar lift necessary to level out the tongue load. One thing to remember, Sumo springs will not increase the GVAR (gross vehicle axle rating) load your vehicle can carry, only assist in levelling a load and keeping your headlights aligned for night travel. I may contact the manufacturer and investigate trimming the length of the Sumo Springs to provide a little more free travel before coming in contact as I don't need 1500 pounds of support. I did not use the 1" spacer that came with the kit. This may be necessary for use on the Silverado Trail Boss which sit's 2" higher from the factory. Otherwise, these are a good option for assisting in leveling your loaded vehicle and have a smooth transition with no noise.

Love the blue ones on a 1500 truck especially since I do not pull a lot. But when I do, it doesn’t drop the truck as much. The black ones were great in my previous vehicle but were somewhat stiff. Not too bad when driving, unless u had a long day at work, then u feel every bump with the black ones.

I put these on a 22 Silverado LT. Basically i wanted to make the ride smoother and also reduce rear sag whenever I'm Towing my 26 ft Keystone travel trailer. I have had these for about 6 weeks now and just took the camper out this past weekend. I got to say, the springs definitely make the ride more comfortable. I use a weight and sway setup as well and adding these springs worked beautifully . I highly recommend.

Easy install. Done with install in about 20 minutes. Great when I am towing my travel trailer. Rides very rough without trailer when going over bumps. —UPDATE— Absolutely HATE these in the winter time. It seems like they freeze ROCK HARD.. you go over a bump and it hits so hard it is unbearable. Do NOT recommend for cold climates.

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.

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.

These are awesome! Great support without all the hassle of a bag full of air

I purchased these to improve the towing on my 2021 Silverado. I tow a 8700lb travel trailer, and with the addition of the SumoSprings, the truck was much more controlled. It seemed to stop sway side-to-side as well as front-to-back. Installation was easy. Very happy with my purchase.
