Rear Suspension Support

SumoSprings helper springs are great for pickup trucks. Towing or hauling a heavy load can cause sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the truck's weight. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.


SumoSprings Rebel installed showing separation of 2-piece springs

The innovative 2-piece design of these Rebel springs allows for unlimited suspension travel. This means that there will be more movement in your suspension when you're unloaded or off-roading, which makes your ride smoother and more comfortable.


Each spring has 2 pieces. One piece attaches to the frame of your vehicle. And the other piece attaches to the axle, typically above your existing factory leaf spring. The pieces come together to provide support when you are towing or hauling a heavy load. When you're unloaded, they separate so that they don't restrict the movement of your suspension. The closed-cell urethane springs also act like a shock absorber to dampen road vibration.


SumoSprings compressing under load

SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.


The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.


Durable, Custom-Fit Springs

These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).


SumoSprings expand and compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts, and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.


This kit comes with custom-fit brackets that are designed to easily bolt onto your vehicle.

Swapped out a set of air bags for a pair of Sumo Springs. The truck now self-levels when I load my slide in camper or other heavy loads. Truck handles better as it's not floating on two balloons. More stability in turns and cross winds.

Review from a similar SumoSprings Rebel in Vehicle Suspension


We have a 2009 build F53 chassis on our 2010 Windsport 32A. I ordered these Sumo springs for the front axle. Hated how bad our coach dashboard would shake and rattle when going over bridge transitions, potholes, and concrete roadway section breaks. Took about an hour and were easy to install alone. Couldn't believe how much these helped the front axle. Worked so well I recently bought a set for the rear axle also. Those are a bit harder to install due to having to drill holes in frame rails to mount the upper bracket and glad I had friend to assist me. Would have only taken a little longer without the help but still easy to do by basic mechanic skills. With having both now we can certainly tell the difference and wished I had bought them sooner.


Comments
Our Sumo springs have been the best addition we have made to our coach. Now retired, we have been getting out and driving farther and the Sumo Springs have made the ride so much better. Highly recommend them on this F-53 chassis.

The front Sumo Springs made a major difference in the stability of my Winnebago motorhome. It handles the bumps much better without major jarring of the passengers and dampens the side to side motion in turns and under crosswinds.

Review from a similar SumoSprings Rebel in Vehicle Suspension


Just Installed my Sumo Rear Springs. They went in real easy on my Dodge Ram 3500. The thing that took the most time on the install was jacking up the frame 3-4" to make enough space between the axle base and top of frame to slip in the entire lower and top sections of the Sumo Springs. Once I did that, I narrowed that space by letting the frame down a little but not all the way. Just enough to catch the receiving spring and leaving a half inch gap between the two sections. This allowed me to easily rachet the bottom u-clap without a problem and keep good alighment. I know I'm going to love this product once I hitch up. No more 2' drop in the rear end once hooking up to my 15k 5th wheel. These springs are stout but no so stout I'll beat the hell out of my body when hunting the rutted roads of the great North West. Thank you Jessie for your expertise and steering me toward the perfect application to meet my pulling and off-road needs.

One year ago I installed Sumo Springs front and rear on my class A motorhome. This upgrade is the best suspension add on for improved sway control and overall handling. etrailer helped me make the proper choice based on overall vehicle weight and specific chassis. Fast shipping and fair pricing.

Review from a similar SumoSprings Rebel in Vehicle Suspension


They fit fine and installed as described in the printed instructions. Reasonably easy overall, even for a novice like me. My only comment is that the video that was included showed a different set up than what was delivered. That made me unsure if I had the proper system for my truck, which indeed I did, but the difference between what was shown in the video that was "for my truck" and what was in the box had me wondering. Never-the-less, all was correct and went well.


Comments
Product is excellent. The springs really reduced the squat I used to have in my truck when I hooked up my fifth wheel camper. Actual reduction in squat was around a 2 inch change. This also keeps the nose of the truck from rising in response to the rear sag I used to have, which makes the overall handling of the total rig a bit better as well. Also, the ride, while connected, is noticeably smoother and feels more stable while driving in stout crosswinds, which we frequently enjoy, here in Oklahoma.

Review from a similar SumoSprings Rebel in Vehicle Suspension


The Sumo Springs that I added to my 2020 Fleetwood Bounder motorhome (along with a Safe-T-Plus) seem to have corrected the ride & handling problems that I was experiencing. I rated the product 4 out of 5 stars because I have only driven the motorhome 20 miles of so home from the shop. The route did, however, include some rough pavement , narrow lanes & construction zones which were MUCH more difficult before. In all honesty, this is probably a five star product. I can’t wait to take a longer trip & see how it does.

Review from a similar SumoSprings Rebel in Vehicle Suspension


I unpacked everything and it was in good shape. All parts were intact and individually protected with paper. The directions were easily understood and very descriptive with all parts lettered with pictures and corresponded to a part and item #. One portion of the front diagram showing the leaf spring attached to a 90 degree I beam should state that is the axle. At the top of the diagram showing the frame rail, it would help if indicated somewhere we were looking at the outside of the frame rail. Those two things would help orient the viewer to what is being looked at. Also, the note at the bottom that says "Driver Side Front" with an arrow, should be in larger print and bold text. The actual pictures on the back side with the instructions should also say (at least in the first one) "outside of frame rail". To sum things up it took me 3hrs to install the driver's side. Mainly because I broke loose the welded nut on the frame that holds the bump stop and I had a heck of a time getting a socket that fit on it so I could get that darn bump stop off. Having said that, it only took me 45 to 50 minutes to install the passenger side once I knew what I was doing and had all of the tools handy. As a final note, it would be helpful to include a tool list such as 3/8" drive socket wrench with 4" or 6" extension. 13mm and 15mm deep sockets to remove Ford bump stops. Standard 9/16" ratchet wrench and or extra open end/box end 9/16" and a deep 9/16" socket. All of which only need to be 3/8" drive. I look forward to my next trip with the SumoSprings installed.

Review from a similar SumoSprings Rebel in Vehicle Suspension


Recommend there springs for any coach without air ride. These took the ride of our 2022 Coachman from that of an empty dump truck to as good of ride as my Ford F-250 SuperDuty. etrailer really know the products and can help you find anything you are needing. I also installed a rear track bar and front steering stabilizer and this has changed the entire handling of this short Pursuit 27 XPS. Can now set the cruise and relax while I drive. The only negative I had was when I removed the front factory bump stops the nuts are not welded in place on my f53 and my frame in that area is boxed in so you had to use existing holes to put the nut back in place. I spent 2 hours on the first one then when I used wire and duct tape to let it down into place the second one took no time at all. This is an issue Ford needs to correct it did not have anything to do with Sumo Springs or etrailer.

These things are amazing! I had doubts, but I figured for the price why not give it a try. The sag is gone when pulling my 5er. My 350 has a 3” lift and sits perfectly level unloaded so any sag shows instantly. These “springs” eliminated the sag and made the ride10x better. Only dropping one star because the kit only came with 4 flange nuts, supposed to have 8 in the kit. Luckily I had 4 with the correct thread pitch laying around.

My ram deisel would squat an inch and a half in the back when i hooked my empty gooseneck to it. After installing Summo springs it only lowers 1 1/4 inches with a 7ton load. More stability with the truck level and wieght on steering axle. More lateral stability for the dips in the road. A must for any one hauling heavy with s 3/4 ton truck

My THOR motor coach has the Ford F-53 chassis. I rides like a truck. That should not be surprising as "it is a truck." I purchased and installed these Sumo Springs and even though it will never be "air bag" suspension, the Sumo Spring made a wonderful difference in improving the ride. I would recommend this add on to everyone and as I meet similar motor coaches on the road, I show them the Sumo Springs and I do recommend them.

Review from a similar SumoSprings Rebel in Vehicle Suspension


Preston did a great job helping me spec in the correct springs for my 2016 Thor Hurricane 27K on a F53 chassis. Placed order with him over phone and received springs two day's later. I just installed them and took Motor home on a test drive around town on bumpy streets and what a difference it made. Drives more like a truck now and less like a boat. I also installed a steering stabilizer spring and did the cheap handling fix to the sway bars. Well worth the time and effort. I did notice that the etralier installation video shows the bottom brackets of the spring installed with the "U" down which is opposite the mfg's printed instructions. I did mine according to the printed instructions cause it seemed to make more sense. Probably no big deal either way. Thanks etrailer. I'll be contacting you guys when ready to do the back end of my motor home.

A great addition to my one-ton. The ride is smoother, how much you might ask? Enough to say it's worth the money. In the picture, I have my 5th wheel hooked up so you can see how the Helper Springs are going to make the bumps smoother because there is a cushion there already.

Review from a similar SumoSprings Rebel in Vehicle Suspension


When you look at the bumpstop and all the travel it can go, it makes sense to fill that space with a constant contact chusion, such as the Sumo Spring. I have a 2011 F53 chassis supporting a 32 Class A motothome. 16,000 GVW and no slide. I only installed the fronts to see how they worked. I did it myself and it took about 2 1/2 hours. If I can do it anyone that can work a wrench and understands basic mechanics can do it. I'm 60 and it's a tight space under there and takes some effort, but the jobs not hard, just doing it is hard and uncomfortable. My motorhome would ride very rough on the same roads my car ran smooth. The Sumo Springs were an improvement. They did not solve the rough ride on real poor highway, but on normal rough roads, they were an improvement that will benefit the ride on more roads than not. I now plan to do the rears when I get time.
