I added these on my 2016 Ram 3500 4x4 pickup. They have the perfect amount of space between the axle ( 1.25”)and the sumo spring at ride height to not feel it unloaded. Once I hook up to my 37” 5th wheel, they squish down and help with the 2600 lb. pin weight. These are awesome!! Highly recommended!

Was very simple to install. I did not have to lift my truck as videos on youtube suggest. Just removed the stock bumbers and replaced with Sumo. Took about 30 mins to install. Suggestion is to make sure you use the locktite for the center bolts the spring is actually attached to.

Easy install, little effect on ride with no load on truck(1" clearance). More stable feeling with 5th wheel attached. Overall very satisfied.

I have a 2022 Ram Power Wagon, This product SSR-312-47 does fit ( rear ) and works good. Just remove factory bump stops and install. With the truck empty there is about 1" of clearance between the bottom of the sumo spring before it engages/makes contact with the axle. Which means you will not feel any difference with ride quality on " normal" driving, unless you hit a big bump, but even then I almost don't notice it. This will help out a lot when I hook up a heavy load.

I have a 2021 Power Wagon and the suspension is soft. Great for off-road, not so great for towing. These REALLY stabilized the truck when towing my 6,000lb travel trailer, even though I already have a weight distribution hitch. Zero maintenance unlike airbags and the ride is unchanged when unloaded since there is a 1” gap between the Sumo Springs and the axle. When I load the bed heavily or drop the trailer on they come in contact with the axle and it sags about 1” less than before I installed these. The biggest difference is the side-to-side stability; there is much more control and less wiggly trailer feeling in wind, sudden swerving, bad roads, etc. I’m really impressed. If you’re looking to stabilize the back of your truck without dealing with airbags I highly recommend giving these a shot.

Make sure you do your homework before you buy. I was lucky enough to speak with a rep before I bought. I would have bought the ones that were too stiff. I ended up with the mid grade, black ones, and they are perfect. Very much controlled the rear sway when towing. Glad I got them.

I love these things. I use them on my lifted Ram 2500 when towing the camper. They screw right on and off so I only run them when towing.They help quite a bit with stability when towing.
