Rear Suspension Support

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.


Installed spring when it is not compressed

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.


Installed spring when it is compressed

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 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.

Install was super easy and the product does what it claims to do. Hauling the horse trailer with these added on is much more stable (no pun intended) and the sway is almost eliminated. 545406

The installation was relatively easy and straight forward. I’ve not yet attempted to hook up to my 5th wheel to see if it’s going to reduce the sag I was seeing that moved me to try this product. So this review is really about the install. 620456

Shipped fast. Easy to install. Work seamlessly. I put these on a 2018 F150 HDPP. I wanted to retain the factory ride quality when empty and have more support when loaded near my GVWR. With the 1" spacer, they nearly touched the axle (1/8" space) and make the ride very firm. So I removed the 1" spacer and the ride quality was indistinguishable from stock on all but the largest bumps. These Sumosprings engage so smoothly that you can't feel the initial contact, it feels like the springs just get progressively stiffer at a rate that is faster than the stock springs alone. Note, I slightly rerouted a cable because I thought it might contact the Sumospring and wanted more clearance for piece of mind. I don't know if this is necessary on the f150 or not, but it I know others that have done this as well. This adds a little time to the install. But still under an hour including finding misplaced tools. 520312

I installed these on a 2017 Ford F-150 SuperCab to stop the initial rear-end sag common with towing a trailer. These pickup trucks have springs regulated for a very smooth ride WHILE EMPTY, as most PU's are used as a personal sports car. The SSR product removes the rear sag, without causing a harsh ride. Easy to install... no maintenance needed... no air-bags to constantly leak. I had already installed Hellwig after-market sway bars on the rear, and also replace the puny Ford OEM front sway bar with a Hellwig product. Together with the Sumo product, there is NO side-sway at all. This product provides extra support, without detriment to the ride comfort. 682449

This helped so much with bounce. Install was very easy on my 2018 F150 did not even need to remove the tires even with the extra 1 inch spacer. Thing to remember when you install them you put the bolt in the right hole. If you dont it will not sit right on your axle when you put weight on it. After my long trip with TT my back end did not bounce like crazy. My tuck does not have max tow so suspension is not tight. This made it like i had max tow package. After my trip I removed 1 bolt and removed the 1 inch spacer and now back to normal ride. You can leave spacer on it will make ride a little stiffer. But wife did not like that. I don't mind removing 1 bolt and add/remove spacers when needed. Also no bag to pop or leaks. People that post pics or say did not site right. Only 2 things can cause that. 1. Put into wrong bolt hole when installing. 2. Too much weight. You can't go wrong with them. They do what they said they do. 705252

I have a slide in camper on my F-150 and it caused a little sagging and some swaying in turns. The Sumo Springs do everything they say they will do for your truck. Installation took about 30 mins, the instructions were super easy to follow, 2 sockets (1-13 mm and 1-15mm and one 15 mm box wrench . After installation I could tell the difference in the handling of my truck immediately, less side to side sway and about 3 inches of lift at the rear. Definitely worth the time and money. I would recommend these to every truck owner who hauls either a camper or a heavy load. 900572

Massive improvement to my 2018 Max Tow package F-150s towing stability with a 7500lb GVW travel trailer. Does not eliminate chucking and such, but dampens all of the undesirable movements to a negligible level.

Ordering from Etrailer was great. Fantastic customer service and fast shipping. The Sumo Springs installed very easily in less than an hour. The additional suspension support feels like it is going to help greatly while pulling my 28' 6500# travel trailer with my F150. It has a bit stiffer ride while not towing but I'd say it is minimal. I think this is going to work well thank you Etrailer and thank you Emily in customer service! 883848

Got my order really fast!! Put them on my truck and it made all the difference!! Very pleased and ready to go! Glad I went with Sumo Springs and saved a lot of money. I ordered these because pulling my camper, and having it all sag in the middle was not good. My camper is now level when hooked to the truck. 831655

This installation was on a 2014 F-150. I tow a Winnebago Micro-Mini 5th wheel with a hitch weight of 1,060 lbs. Frame to axle stock was 7.5 inches. The Sumo springs without the spacer lifted my PU 0.5 inches. The Sumo springs are always in contact with the axle so my ride has greatly changed. As I am an outdoorsman and travel on a lot of gravel roads fishing and hunting, I will have to remove the Sumo springs when I am not using the trailer as the ride is totally unbearable on any unpaved road. As for using the Sumo springs with the 5th wheel, when loaded the springs compress 0.5 inches to a axle to frame distance of 7.5 inches (ie stock) The ride with the camper is very stable and there is no excessive bounce. The springs perform very well when loaded. In my research of this product it is advertised that there is a 1 inch gap between the sumo spring and the frame to allow for a comfortable ride. That is not true and is the reason for my poor review. 822363

Installed on my 2010 F150 XLT to help with sag when pulling our camper. Very easy to install, even with my tires on. Used my large floor jack and raised the frame to create more room. To help with the removal of my stock jounce bumpers, I sprayed PB Blaster on the end of the bolt-located in the opening in the frame. Sorry, I didn't take any pics on the project. 800956

  • Recommended Rear Suspension Enhancement for Maintaining Level Ride on 2018 Ford F-150
    Jounce-style springs like the SumoSprings # SSR-117-47 you referenced for the rear axle of your 2018 Ford F-150 do a great job of allowing your truck to better support heavier loads, but they aren't going to eliminate sag. This is because there's still going to be a gap between the spring and axle, meaning the rear of the truck will need to drop a bit before they will even engage. Since you aren't a fan of the idea of air bags, your best solution for maintaining a level ride when under...
