Specs:
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.
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 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.
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.

Added confidence to pulling 35' 5th wheel.
e- trailer is excellent to do business with
Love them already. Super easy install, excited to put a travel trailer on and see how much they help the suspension. Already notice a difference with speed bumps and potholes. 2020 chevy 2500HD
I had these on my last truck and they worked so well that I bought them for my new truck. 2022 Chevy 3500 crew cab long bed. I use my truck to carry both my truck camper which is a Northstar 850SC or when I pull my 31-foot travel trailer.
To make them fit I had to cut off about an 1 and a 1/2 inches of the top piece to have clearance. Didn't expect that.
Fast delivery and easy install!
Easy install.

Front and rear Sumo Springs installed. Have not had a chance to hit the highway as yet. Locally a very good ride. Thanks to Joanne K. for all of her help.
Review from a similar SumoSprings Rebel in Vehicle Suspension
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
These helper springs made an amazing difference in the stability and ride comfort in our coach. Improved cornering and bounce control were immediately apparent. Plus, crosswind driving is much improved. The split design makes leveling easy as I typically raise the front of the coach rather than the rear. Installation is a lot of work, but can be done yourself with the right equipment. Very pleased.

Sumo springs along with a steering stabizer, new shocks, and oversized sway bars seriously tightens the ride on older model RV with an f53 ford chasis. Long hauls become a lot less strenuous. I also put a memory foam and high density foam seat cushion on the driver's seat. We can travel all over with a lot less fatigue from fighting the wheel and pucker factor from blowing around the road. I took about 3 hours to unstall all 4 sumo springs.
Review from a similar SumoSprings Rebel in Vehicle Suspension
The work great! Was going to go with the Air-Ride air bags in the front but folks had noted that the bags are strained when the leveling pulls the front wheels up to the point of coming off the ground. Glad we went with these. The person I put this on for is Handicap (or Handicapable as she says!) and these do not require air or making sure the pressure(s) are correct and holding.
It was a pain in the butttt get the original jounce bumper off the drivers side, but we muscled through it!! Thanks, Amy, for your help in ordering!! v
Review from a similar SumoSprings Rebel in Vehicle Suspension
Adding a pair of SumoSprings to the rear axle of our 2015 F250 did little to help level the vehicle when hauling 500 to a 1000 lbs of feed or other materials. When pulling a bumper pull tandam trailer with a UTV, tractor, etc.,these springs did not hold the pickup level. We have since replace the leaf springs with OEM parts and all is better. The SumoSprings is a very good idea however did not solve our concern and probably should have saved the cost and replace the leaf springs first. Please note that this F250 does not have a goose neck hitch and it is rare to be overloaded. We use a one ton for those loads. Thanks.

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.

I really like the improved ride that these SumoSprings made in the ride of my motorhome. I changed out the old style Sumos for these two piece Sumos and would definitely do it again. It doesn't necessarily take away the bumps but it makes them smoother or not as hard of a bump. Also James was very helpful and easy to work with while placing my order and kept me informed on the status of my order.

Immediate improvement in sway control and ease of driving. I installed these in a few hours at my leisure. Did I mention I am 65? 2019 Winnebago Sunstar 35LX

They do what they were intended to do - reduce the effects of slightly overloaded factory springs.
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.

WOW! what a difference it made in the ride of our coach. The jarring in the cab is better. Installation was fairly simple with hand tools. Worth every dollar.

These springs definitely helped the stability of our motorhome. eTrailer is THE place to go with RV issues/repairs. We have dealt with them for years and have no regrets. Bob is our "go to" guy. He, as well as all of eTrailer's other employees, are top-notch!
Review from a similar SumoSprings Rebel in Vehicle Suspension
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.
