Set of Rear SumoSprings fits 2004-2025 Sprinter 3500 and 2017-2025 Sprinter 4500 (2WD Only) | 1400 lb Capacity at 50% Compression | Simple Installation

Put the front and rear Sumo springs on a 2017 Sprinter 3500 RV to help with sway and body roll and they exceeded my expectations. They were difficult to install at first until I noticed the Sumo springs are about 3/16” wider than stock. A quick trim to the longer end that goes in first made them much easier to install.

Oh these are a must for class c motor homes . These help on swaying and turning in parking lots gas stations etc. I highly recommend these you want believe how much this helps in driving . I got the yellow one they stiffer there are three types for my model. These are for pickup trucks too. I did not do the front just the rear raised body up about four inches in rear.

I had my eye on the Suomo bump stops for a while, and honestly, I was skeptical. I mean, can a rubberized cushion really make a difference in a ginormous vehicle like our 2021 Winnebago Boldt? It’s not like we're trying to park a golf cart! Well, let me tell you—the effect was immediate! The side-to-side sway we experienced while navigating driveways, potholes, and the uneven shoulders of life (seriously, what are those?!), is officially a thing of the past. It’s not just reduced; it’s *gone*! As a natural skeptic, I was all set for that classic “Am I just trying to justify the expense?” moment, but nope! This was legit. Now, let’s talk installation. It was pretty straightforward—like trying to assemble Ikea furniture without the emotional breakdown (almost). The back slid right in, but for the front, you have to press it into the bracket with more pressure than you’d think is safe for rubber. Picture me wrestling with it like I was trying to win a tug-of-war competition! And let’s just say, the front bump installation required some serious yoga moves and a collection of specialized socket adapters that would impress even the most seasoned mechanic. I might have yelled a few words that would make a sailor blush, but hey, all part of the fun, right? In total, we’re looking at 20 minutes for the rear and a dramatic hour and a half for the front—complete with grunts, groans, and a newfound appreciation for both rubberized cushions and patience. But at the end of the day, it was totally worth it! Our Boldt now rides smoother and that irritating sway going from pavement to shoulder,driveway or parking lot is 80% or so gone. Now going on year two and We’re great fans of smoother Suomo bump stops! Maybe beefed up shock next.

We have a '17 Thor Four Winds on a sprinter chassis. as it's a rather tall class c, when going around a corner or over bumps, it 'wallows' quite a bit. Enough to make my wife nervous when she was following me in the car one time. I ordered these and had them put on by an RV repair shop when I had it in for another reason. when I pulled out of the parking lot, I could immediately feel the difference! The RV felt much more attached to the road, and a pleasure to drive. My knuckles are no longer white when I see a big truck approaching in the other lane. I plan on getting the ones for the front, but these really do the trick on keeping everything solid. They should be standard equipment!

well the overall product is good - welcome idea but i would prefer air adjustable ones - the ride is non adjustable - they do not have air adjustable bags for the sprinter rv's - they were easy to install although until i figured it out they had me cussing one time! once installed i tested it on a 3 mile trip - i also installed the front sumo springs - and opted for the 1000# black version - i do not recommend these on a sprinter even my class a - install the blue front ones - now for the REVIEW - although the wind sway and semi passing sway was almost no exsistant, it did not come without a price - the price is a rougher ride - little more slamming over pot holes and rough parts in the road - a lot better after i changed the front ones to the blue 500# version - all and all- was it worth it ? - i say yes as rougher ride is better then white knuckling any time - i am keeping them at least until they come out with air ride bags!

When we had our Sprinter based RV, the amount of side sway when entering driveways and parking lots was extreme. We placed Sumo Springs on the front and rear, and eliminated 90% of the motion. It was money well spent, and a DIY project for most people, if you have Jack stands. An hour to do front and back combined. It even improved the side push from passing 18 wheelers.

Purchased a used 2017 Winnebago View from RV One in Greensboro NC. Ordered the rear yellow Sumo’s and installed them it the bdealership before leaving for an 820 mile trip home. I’m a first time C class RV driver but a long time EMT/Paramedic and drove Ambulances for years before retiring. So I have driven or rode in the back of a similar vehicle. That being said and after watching a few videos, I purchased Sumo’s for the rear and brought them with me to install for the trip home. I waited until I got home to install the front ones. I’m glad I installed the back ones, the ride home was much easier than I anticipated. With just the rear’s the side to side roll was greatly reduced compared to the ones I test drove prior to buying this RV. I wished I had installed the front ones before I left. After I installed the front’s, which were pretty easy, the ride has greatly improved front to rear! I would recommend these for a much better ride, experience, and less white knuckle driving!!

I installed this product. I should say that it can be easy for me to install but might not be to others. I installed it to my Class C RV to see if it can make a difference. I noticed that the ride is more stable and not as bouncy as before. Will see and update this when i use it for a longer ride trip. Definitely i will notice the difference. Update. I drive my RV last week and it was raining hard on Highway 101, it used to sway buy the stability of the ride was really felt stable and less rocking back and forth with full tank of 50 gallons of fresh water. Ride was even smoother.... I'll give it a 5 star after this road test....

Installed front and back sumo springs on my sprinter based c-class rv. They improved the handling and winds don’t push the coach around like it did without the springs. The springs significantly dampen vibration making the coach quieter - less rattles and squeaks. Installation was a breeze. I highly recommend this product.

As described. Made a big difference. Worth it.

Well worth the price, installed them myself without problems.

What a difference do these made to the ride of our RV!! It's A bit challenging to install, but you already know that when you buy it. This was purchased for a Mercedes 3500 van and the difference between the stock and sumo springs is shocking. See the image for a comparison. Highly recommend buying

Installed on a 2014 Sprinter 3500 Camper (Roadtrek CS) They were relatively easy to install, and helped dampen the nasty back and forth rocking of the van when entering or exiting a driveway or parking lot at an angle. They are a fast and non-invasive modification that seems to be working well. Time will tell how well they perform long-term.
