Great product. Have put them on 2 of my 2500hd trucks. Makes a big difference hauling heavy.

They fit but are a pain to get seated. I’d go with real air bags next time

All things considered, I can't say they did what I was hoping for. The installation took less than 20 minutes, it really was very easy. The price for a set of Sumo Springs I thought was a little high given what they are. Once installed, I attached my fifth wheel to my 3500 SRW truck. I want to be optimistic and say they put an inch or so back in the rear suspension. My goal was only to help level the truck when loaded, I didn't have outrageous goals. The ride was comfortable and stable but still noise high. All the hype I heard about these "springs" I had higher expectations.

Works great for for the right person. I have a 2021 GMC 2500. It took me 5 minutes to pop out the stock bump stops and put the super springs in. I loaded the bed with 2400 pounds of concrete bags, and I only had 2 inches of total squat. (1.25 inch gap between the super springs and axle... And then about 1 inch of compression on the springs with 2400 loaded). The truck drove like it had nothing loaded in the bed. These are perfect for me, but if you're looking for fancy air bags then go ahead and get them!

Super easy install. Have them on 2 2022 3500 silverados. Work great with or without loads.

This product didn't work as advertised for a 2023 Chevy Silverado 2500 HD. Once installed you could easily remove it with your hand. Could have falling off while driving.

For my particular application 2015 Silverado 2500hd with a 35’ 5th wheel cargo trailer. They installed in about 11 min including jacking up each side. Nothing fancy, jacked up on the front leaf spring mount, popped the old ones out with a thin long flathead screwdriver, added just a little soapy water to the install side, pushed them into place and dropped the jack. They got pushed all the way in when it landed.It only helped ride height by about an inch, but overall it doesn’t dip and bounce down the freeway and even cut down on the rear hopping down the freeway.Relatively cheap, extremely easy, and effective for both towing and not towing.

I think for the money these are a no brainer. The ride quality is good with no load and with a load, there is more support. Instead of spending $1,000 on air bags I decided to try these. I have a GMC 2500 Duramax and I pull a travel trailer that is around 7K pounds. I had some bounce on the highway when I would hit dips because of the trailer and the load in the bed, that has all but disappeared.

Product works well a little harder to install then what the instructions said. But in the end does what it was designed to do.

Very easy to install. Unloaded these Sumo Springs have softened the bounce. Trust this will reflect with a 5th wheel attached even better.
