- Super simple install, believe it’s a 1 on 1-3 install complexity/challenge. Definitely do’able for an average DIY’er!
Keep your Mercedes Sprinter from sagging!!
SumoSprings for the rear end are great if your vehicle is pulling a trailer or carrying a heavy load. They will stabilize your vehicle and help to keep it level. Made as rear alternative to traditional air bags by Air Lift and Firestone. These micro-cellular springs differ in that they require no inflation and will not leak or rupture. While not adjustable like air bag helper springs, Sumosprings will help to reduce sway and reduce sagging in the rear end. Just mount and forget. Included with all kits are steel mounting brackets and hardware. All are custom fit for a simple installation.

Safety first. Thanks for sharing.
Installed front and rear sumo stops today, the rear set required the gentle bend of the brackets with a set of vise grips. Once installed I tapped the brackets back to shape. Thanks for that advice. I am running a 2021 3500 cargo dually converting to a campervan.
Hey Kenny that is great to hear the video helped! Good luck with your build.
I put a set of these on the back of my Tundra and liked them much better than the air bags I had. They have a pretty good ride when the truck is empty, the air bags were way too stiff.
Hey so how many miles on the Tundra?
I see so many of these videos of the install of these suspension 'upgrade'. They sure sound like they're a good performer.
My concern is these mounting points are going to develop stress cracks over 150-200k miles or far less.
I'd love to hear long term tests
Great quick review, so now is "your fault" that I got the Front/Back and the SSA55 Leaf-Spring on my 2019 Sprinter.
I am also thinking about adding a leaf or two on the back-springs. 😀
Great job and will look forward to see what other "gizmos" you get me thinking about grabbing gor my Sprinter. 😀
I see the original shocks Monroe?
Yes those are the original equipment shocks
Have the same but mine are completely pulverized and no longer work as they should and have done.
Curious in what condition yours are after two years?
I have already replaced them at the front because they were also completely pulverized and were replaced by sumsprings under warranty, it seems that these are already getting worse within a year.
It's OK if the SumoSprings isn't in constant contact with the axle. In fact, it's better that way. And they are not meant to lift your vehicle.
Thanks, appreciate your note. Pretty impressed with the Sprinter chassis suspension set up. Just hauling around about a thousand pounds I still see a gap in the rear sumos. Perhaps this should be expected until the van is fully built out…?

Curious do you have a before and after measurements for both the super springs and the sumo springs? I currently have the sumo springs and thinking about adding the super spring. Thanks again for the great video.
By the way I added Falcon shocks on the rear and Bilstein B6 upgrades w/sumo springs on the front. Sway and wind has now be reduced significantly. So hoping the to add super springs on the rear will eliminate a 1” of sag.
I should have taken before measurements, but I didn’t; although, I may be able grab measurements off the Benz lot from another Sprinter. Stay tuned, and thanks.
I have a sprinter class c, I installed the yellow ones in the rear no lift . This morning I installed the blue ones in front. Maybe 3/8 taller, I measured at the fender on dirt so not very scientific. At about 11,000 pounds it now drives and rides like it should. Thanks y’all!
Do you think if you were to heat them up or cool them down it would go in easier?
So for the slow response. Not sure I would heat them up as worried they might melt, for me it about a lot of manipulating and adjusting the metal receiver tabs on the van.
Have been researching this and lift kits - it appears that sumo springs while good in preventing sways is not meant to be loaded. The frame area which is not meant for load bearing will crack. Please see attached from Agile Offroads start at about 4 minutes 35 seconds into the video.

Thanks much for sharing. My take away from Agile’s comments is over weighting issues. If I over do tow, with my built out van, having awareness of this potential is important!
No worries…I am learning too, always nice to learn and share…cheers
