1,500-lb Capacity. Upgrade your Ford F-150's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
A heavy rear 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 weight of your vehicle. 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 vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
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 closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.
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 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.
The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

Very happy with this product. My 2018 F150 was sagging when towing my fifth wheel camper. These leveled it out. When you hit a bump UNLOADED, they do make contact with the axle and stiffen your ride a bit but other than that ride is normal on relatively smooth roads. But this is to be expected if you're going to make your truck capable of carrying heavier loads. During installation, on the driver's side, I did have to slightly bend one vehicle bracket out of the way so the spring wouldn't contact it during operation.
See photo, silver bracket near two zip ties which I added to further secure wiring harness to the bracket.
Received earlier that the estimate using the free shipping. SumoSpring helpers were well packaged with good instructions and even included Loctite for the bolts. I already installed the sumos and towed my boat. Greatly improved stability and reduced squat without ruining the ride, with or without the boat trailer. These people are real pros at what they do. Great job!
That is awesome, just what I needed, maintenance free no worrying about adding air smooth ride when I tow my camper
This is my second set of sumo springs. It is a great help stabilizing our F-150 while we tow our half-ton towable fifth wheel. Well worth the money!
Installation of the Sumo spring kit was relativity simple. Jacked rear end up and removed tire and wheel. Removed factory joust. After studying spring and bracket got it mounted on the second try. I used the long bolt supplied with the bracket for the spring. Could not get it to go into the bracket with it mounted on the frame. Removed bracket and put long bolt in the bracket and reinstalled on frame. Bolted on spring. Installed other side with no problems. With travel trailer connected to truck my rear bumper is almost two inches higher. Truck sets level now. Haven't tried a road trip yet but one is planned soon. Will update when I get back.
Product works perfect, just like advertised, simple installation took 35 minutes both sides bolt in.
I tow a 24’ enclosed car trailer with a car & golf cart inside. Very little sag, beats the trouble of air shocks,
or installing air bags. All your products are very helpful
To the do it yourself mechanic. Thanks again for a great product. PS no one paid me to say this.
Just installed a pair of rear Sumosprings on Mt '13 F150 2x.
Easy to install works great with my new 32' rv trailer. My next purchase is Sumosprings for the front. Got more control and hardly no sag is the rear. Yes great investment
I have a Black Series HQ15 off grid off road camper caravan. The HQ15 weights 6000 lbs empty. I have a 2013 F-150 4x4 super cab 5.0 liter max tow package truck! After installing the Sumo Springs the sway and squat of the truck was improved tremendously!
First off Montrell at etrailer was awesome to work with. I was experiencing trailer sag when pulling my camper and the SumoSprings sounded like a great solution. I was excited to receive my order a couple of days earlier then expected also. The installation was straight forward and took less than an hour. I used ratcheting wrench's which help tremendously. I like the fit the rides not bad. Looking forward to hitching up the camper.
Put them on my 2019 Ford Raptor to help with the trailer sway and to level off the truck pulling my 29’ enclosed Trailer. They were easy to install. About 30 minutes. Took them out when I got done using the trailer because I could feel every small bump when the truck wasn’t pulling the trailer. Again they worked good when the trailer was hooked up but you are going to give up ride quality.
I received my order today, exactly when they were supposed to show up. The contents are exactly as described and I can't wait to install them. According to my mechanic, these perform excellent under a heavy load.
So far so good Easy install although brake lines on the drivers side had to be relocated a bit to prevent interference. The real test is when I pull my toy hauler in June.
Easy to install but haven't put a load on them yet. Will load them up next week to see how well they work out. I have a lot of confidence in this item

It hold up trailer better ,but I have a rougher ride.
I installed Sumo Springs on our 06 Xterra right after we bought our Casita 17' trailer. The back of the X squatted a bit more than I liked. I had also noticed before some tendency to bottom out if the car was full of people and stuff. These ingenious devices are a perfect solution for me! They are about 3/4" clear of being engaged with the axle when unloaded, so the ride is not overly affected, but progressively take up some of the weight when the back end starts coming down with load. It now sits very nicely with the trailer connected, no weight distributing hitch and stuff in the back, and no more bottoming. We've put a good number of miles on the X in the last year, towing and not towing, and they are still doing the job.
I should note, the back of my Xterra is lifted about an inch with AAL springs. If that were not the case, the Sumo Springs would be engaged all the time. That will vary with vehicle.
I will also note that they are non-adjustable, unlike airbags. I kinda like that, I didn't want to mess with adjusting air pressure and such. But once they do start kicking in as one or both wheels travel, they do stiffen it up quite a bit. I mean, there's no way around that; you can't take load without stiffening the suspension. As such I think they inhibit upward axle articulation a bit when 4-wheeling, but for us that's not a big deal. Since they do not connect to the axle, they don't affect downward articulation at all.
The pics are shortly after installation, one with the car unloaded, and two with trailer and gear loaded up.
I believe it’s going to be a great addition to my truck when pulling our RV. Looking forward to a smoother, more even ride. I left the 2x4 blocks in overnig8ht and drove around to ensure a good seat for the springs.
Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs
These Sumo Springs were easy to install, even for a 70 year old guy. I tow a 7,000lb camper and even tho I have a nice WDH I still had som sag on my Tundra. These helped level it out when towing and got rid of “some” of the bounce. They were really a godsend when I overloaded the bed with about 2,000lbs of pavers. That weight squished the Sumos significantly but the truck drove and rode great. Better and less expensive than air bags.
The SumoSprings Solo came to the RV Resort today. I installed them on my Titan SV today in less than an hour. Only drove 10 miles with them and they are what I was looking for. In my opinion it was a needed upgrade and thumbs up!

They are working quite well. They engage a lot sooner than the factory stops. I noticed less sag in the rear when the load from my camper was applied. I often recommend them to people at campground when I see their trucks sagging. Great product.
