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.

Video Transcript for SumoSprings Solo Custom Helper Springs Review

Speaker 1: Today, we'll be taking a look at the SumoSprings Solo Line of Custom Helper Springs for the rear axle. You'll want to use eTrailer's fit guide to determine the correct kit for your vehicle. This is what our SumoSprings look like when installed. Yours may look a little different depending on your vehicle.They're gonna replace our factory jounce stops and sit right between our frame and our rear axle. So whenever we're carrying a heavy load, they're gonna give us that extra support that we need. The way our SumoSprings are gonna work is when our suspension starts to sag from the heavy load, these are gonna absorb a lot of that weight.They are gonna work independently from each other so it's gonna help with those off-center loads.

Our springs are gonna have a progressive rate to 'em. So if we have a light load, they're gonna compress softly, still giving us that comfortable ride. But the heavier load we put on 'em, the more they're gonna compress and the more firmness they're gonna have to them.Now comparing to our factory jounce stop, you can see there's a big difference in height. These are gonna give us a lot more compression, whereas our factory jounce stops are really just preventing the axle from hitting the frame.We have a water tank at the bed of our truck as a heavy load or to simulate the tongue weight of a heavy trailer or a fifth wheel. So as I take the truck through my test course, I can definitely tell that there's a load back there.

The engine doesn't seem to be strained that much, but the bumps are extremely harsh and I can definitely feel it resonating through the seat.When I come to the slalom course and I'm going through the turns, it definitely has a lot of body roll and I just generally feel like I need to slow down because it feels likes it's leaning a lot and it's not responding quickly enough to the turns.Now that we have our SumoSprings installed and I have the same load back there, when I'm driving through our course, I can immediately tell a difference. It's much of a smoother ride. Going over the bumps really doesn't feel like anything's back there and it's just a lot more comfortable.When I come into the slalom course, it definitely feels a lot more stable and it doesn't seem to sway as much side to side and it just generally feels like it wants to go faster.These are made of a durable micro cellular urethane that works in temperatures from -25 degrees to 200 degrees Fahrenheit, and resists damage caused by oils, road salts and UV rays. Compared to air bags, these are maintenance free option with no tubes to run or air pressure to maintain. Both will help level your load and provide a smoother ride.

Airbags can be adjusted to suit your needs whereas the SumoSprings are a fixed option.That completes our look at the SumoSprings Solo Line of Custom Helper Springs for the rear axle.

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

The product was easy to install. The Tools needed list needs to be updated. Removing bolt is 13mm. Installing new bolts are 15mm. Also the nuts that are tack welded inside the frame will break loose if any rust or debris are on the threads. Back up wrench is near impossible if to fit if the size is not known. End up cutting the old bolt because of this. That’s not your products fault. That’s Fords issue. With the 1” spacers provided it raise my F150 4 1/2”. Stiffened the ride up. Ready to haul my 5th wheel. NICE 452641


Comments
The Sumo Springs are still performing well. I Hauled our 29.5 5th Wheel from Upstate NY TO Florida through a major 4 State nor’easter. We have also bought a 16’ cargo trailer and hauled it to it’s full weight capacitie. The truck is still sitting high.

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.

I don't really notice a difference on my Ford F150 truck when it is empty but when I attach my 26' trailer that's when I notice a big difference. The truck stays parallel when the trailer is attached and the handling is quite noticeable, much better than without. I would highly recommend this product. 771809

  • Suspension Enhancement for 2018 Ford F-150 With 6 Inch Lift
    I am not familiar with the Pro Comp kit; I did look it up and from the installation manual it seems like all parts of the rear suspension were affected. Can you confirm if there is any type of interference with the leaf spring? Your only option is going to be a kit that attaches above the factory leaf spring but if there is interference of any kind then it would not be a fit.

  • 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...

In regards to the SumoSprings, you will always want to have a safety margin and the above will be perfect for your setup. The springs have a progressive load rate so the 1,500 model with 850+ lbs will have a smoother ride than the 1,000 lb model with 850+ lbs.

    For your 2020 Ford F-150 with 4-wheel drive that gets a lot of different uses - daily driving, towing, hauling - the best suspension enhancement is the SumoSprings Solo Custom Helper Springs # SSR-117-47. The reason is because the SumoSprings compress based on the weight you have in the bed or are towing.

    For your 2013 Ford F-150 4x4 with the 3.5L EcoBoost engine, I recommend using the SumoSprings Solo Custom Helper Springs part # SSR-117-47 which are rated for 1,500 lbs. The reason I recommend going with the 1,500 lb system over the 1,000 lb system (part # SSR-117-40) is because it's better to have too much capacity than not enough.

My favorite part about the SumoSprings is they don't change the ride when not loaded but give the strength and support for a better ride when...

  • Firestone Suspension Enhancement Recommendation for 2017 Ford F-150 with 4 inch Lift
    We have suspension kits that fit your 2017 Ford F-150 that has a 4 inch lift kit but the SumoSprings kits don't have lift kit spacers like the Firestone part # F2582 does which is a fit for your truck. The spacer kit you'd need is the part # F2371 and you'd be set.

  • Recommended Suspension Enhancement System for 2013 Ford F-150 3.5L Ecoboose 4x4
    Your 2013 Ford F-150 Ecoboost 3.5L 4x4 has a rated 5th wheel towing capacity of 9,600 lbs with your 3.31 axle ratio. You cannot tow more than 5,000 lbs when towing with bumper only. You should have no problem on PA roads with your 28.5 foot 5th wheel as long as your loaded weight is under the 9,600 lb capacity. I recommend adding the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-117-47 to help prolong the life of your factory suspension when towing. These springs are a...

  • Will the Sumo Springs Work on my 2014 F-150 with a 6” Lift
    I do have a good option for you as far as upgrading your suspension on your 2014 F-150 but SumoSprings Solo Custom Helper Springs - Rear Axle part # SSR-117-47 are not going to be the way to go in your situation. They are just not tall enough to do you any good. They will fit on there but will have no effect. Instead use the the Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle # F2542 and the Lift Spacers for Firestone Ride-Rite Air Helper Springs - Vehicles...

  • Recommended Suspension Enhancement for 2016 Ford F-150 Crew Cab 4x4
    The Timbren Suspension Enhancement System # TFRTT1504E is a confirmed fit for your truck. With a 1,100 lb tongue weight trailer, this system will help to keep the rear end from squat and your headlights from being too high to see the road as intended. These will act as a shock absorber as well as helping to stabilize your truck when under load. These spring are made for severe service vehicles like tow trucks so I don't recommend then for your truck as they can actually cause your truck...

  • Rear Helper Springs for a 2012 Ford F-150 4x4 and Forest River Stealth Model 1913
    Timbren rear helper springs # TFR1504D for your 2012 Ford F-150 4x4 will definitely help with the sag you are experiencing when towing your Stealth toy hauler. But when not towing or carrying a load in the truck bed you will likely experience a stiffer ride, more jarring on bumps than the stock suspension. For a similar option that features a softer spring style we have SumoSprings # SSR-117-40 rated at 1,000 pounds, or # SSR-117-47 rated at 1,500 pounds. These springs will have more...
