Rear Suspension Support

Towing or hauling a heavy load can cause rear 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.

This is probably the best thing I could have done for my truck. The install was easy. Without these, the truck would drop 3 1/2 inches in the back with the RV on. Now only one inch. The truck is a 2015 F-250. 553859


Comments
After a year of use, Im very happy with the Sumo springs. Much better ride and nobody flashes their hi beams at me anymore because the truck rides nearly level even with the weight of the 5th wheel on.

I purchased the Sumo Springs due to rear end sag on my F-250. They pretty much fixed the problem which was caused by too-weak springs in the first place IMO. No change in the ride quality either loaded or unloaded detected. Prompt shipment & knowledgeable sales staff. Very helpful. 792715

Installation took about half an hour. The fifth wheel with a gvw of 15000# used to sink the truck box significantly. After installing the Sumo Springs there is a minimal sinking of the truck. I highly recommend! 719214

Fast customer service. I easily install them on the rear of my two thousand five F-250 4x4 with factory overload springs. Since installing it is a much smoother ride when unloaded and now only squats about 1 1/2 inches when pulling 7500+ pound camper. The hardest part about installing these was removing the factory bump stops. 613107

Very easy to install. Normal ride unless loaded and ride is smooth, even then. Helps with porpoising when hauling a heavy tongue weight. 658065

Pulling my camper is no longer a “ white knuckle “ experience. These are a no brained if you have a 12 ton pickup and carry heavier loads.

Review from a similar SumoSprings Solo in Vehicle Suspension


These work exactly as stated on my 2018 sprinter class C. They do not make the ride harsh at all. The yellows combined with an upgraded sway bar helped stop the sway of coming out of a driveway tremendously. Sway from wind and being passed by trucks was also greatly reduced. The addition of upgraded shocks make it so that I can drive one handed the majority of the time now. Recently had the chance to test these in a long run of coastal highway one in northern CA, they made the extremely windy road a pleasure to drive, even with the bad road conditions. Only scored a 4 and not a 5 because they do not solve all of the issues by themselves, but are an integral part of a total solution. 663600


Comments
One year later Ive since upgraded the front suspension as well and Im still loving the ride. The idea of driving in adverse conditions no longer impacts trip planning.

Review from a similar SumoSprings Solo in Vehicle Suspension


This product does what it says it will do. One of the issues that I have is the difficulty to install this product. The 2020 Ram 1500 on the passengers side has a stabilizing bar that interferes installing all the nuts on the rear of the mounting plate spring. My truck supposedly has a 1 inch lift from the factory (Big Horn North Edition). I used the plastic extension as recommended in the installation instructions and even with the 1 inch factory lift, using the plastic spacer makes the spring rest on the rear axle with no load in the truck. I'd recommend to not install with the plastic spacer. The ride is much stiffer but I'm OK with that as when my trailer is attached the ride is as expected. 764466

Front & Rear Sumo Springs Just installed the Sumo Springs I ordered and oh WOW!!!!! That is the finishing touches to my suspension on my 32 ft Class C on an E450 chassis and love the results. Bought our coach a year ago and installed Hellwig sway bars ( front & Rear ) Bilstien shocks and Safe T Plus Steering control and that made a huge difference to drivability but then decided to add Sumo Springs, Oh My Goodness with all that I’ve done our coach drive down the highways and byways rock solid. The sumos weren’t to difficult to install considering this ole man has had 3 back surgeries and 2 bad knees but we got it done and I was blown away on the test drive. I highly recommend the Sumo products. 641292


Comments
Still love the Sumos, they do their job. Class C is so much more a pleasure t drive even in wind and large semi trucks passing by, barely a wiggle. I would highly recommend these on any motorhome

Review from a similar SumoSprings Solo in Vehicle Suspension


On a 2015 Ram 1500. The Sumo springs work great. I went from a loaded ride height of 35 inches to 36 1/4 inches. But the real improvement is in the ride. No longer have the squishy rear end wobble that I used to have. Combined with my weight distributing hitch my ride height improves to 37 1/2 inches. Truck is level along with my travel trailer. When I'm not loaded I don't even notice that I did anything. Still rides like factory. My only complaint is in the installation. Eight nuts with washers per spring and there is no space at all on multiple nuts to fit a so met or even a ratcheting wrench. Took about an hour in my driveway. Other than this minor inconvenience, I have to say excellent product. 347254

Review from a similar SumoSprings Solo in Vehicle Suspension


The SuperSpring Solo work as advertised. They definitely help level the load when pulling my 27' camper. My only complaint is that they fit so tight (1/4" gap) between the bottom of the SuperSpring and the axle that as soon you load anything you are already using the SuperSpring. I would have preferred a little more of the oem suspension for day to day driving. 660605

I pull a 24 ft trailer w/ one slide out. It weighs roughly 5K (more loaded). My RAM 1500 is well balanced for the tongue weight and , of course, when not pulling, the truck drives as if the sumos were not there-which they are NOT when the weight comes off. I have noticeably more control overall. Glad to have purchased these. They were installed by Dodge dealership--no issues. A great product. 674123

Great product. Very easy to install. I installed Sumo springs front and rear on my class C Sprinter-based RV (Winnebago View) as part of a suspension upgrade to improve handling in cross winds. The other suspension upgrades included a Hellwig rear sway bar and Bilstein rear shocks. The handling improvement was dramatic. No more sway when being passed by semi’s and much, much better handling in cross winds. I am very happy with the Sumo springs. 656765

Review from a similar SumoSprings Solo in Vehicle Suspension


I've had these for 1 year now for my 2016 Tundra and they are exactly what I needed!!! I couldn't be happier! Prior to purchasing and installing these, when I towed my 2 horses with my 2 horse slant bumper pull trailer, I was concerned about cargo weight in the bed of my truck so I was limited to gear I could bring camping and hunting season with my truck. Since adding these I can pull the horses and load my truck bed to the max including horse feed, hunting gear, coolers with food you name it and my truck doesn't even squat a bit! The ride is great with a load or without and my performance off road is still fine too! These proved to be a great solution to my needs and frankly better than pricey air bags. 673850


Comments
Were glad to hear that youre pleased with your purchase. Please keep in mind that the Sumo Springs product will not increase the capacity of your rear truck axle. The tongue weight of the trailer plus the weight of the cargo carried should not exceed the trucks rear axle capacity.

Review from a similar SumoSprings Solo in Vehicle Suspension


I Received the SumoSprings Solo Custom Helper Springs shipment today and installed them on my 2017 Chevy Silverado 1500 standard cab long bed truck. It took about 30 minutes to install the helpers springs. I watched the install video and read the installation instructions on the etrailer website while waiting for the shipment to arrive. They were easy to install without jacking up the truck, I laid flat on my back and slid under the truck on my garage floor and had no problems at all. After installation I hooked up my 20 ft travel trailer and went on a test drive. The helper springs made a big difference and gave a more solid stable performance with the truck while towing my 5,000 lb travel trailer. I've installed airbags on previous trucks and I believe for the money and easy installation this is the best option to improve towing performance. 725590

Review from a similar SumoSprings Solo in Vehicle Suspension


Purchased for a Tacoma 4 dr, long bed, with a fiberglass cap. I have the TSB/recall replacement spring pack. With this set up I had a decent ride, and better support over the OEM springs, but still see that the springs provided only minimal improvement when loading in the bed say 300-500#. If so loaded (camp gear, MC gear, 2-3 persons in cab) on moderate unpaved roads the OEM springs were at max load and had we too much frame sag. WITH the addition of the SumoSpring kit I found my truck when UNLOADED handled the same, but did have less body roll in the rear. At rest the frame rail is just touching the SumoSpring and wheel well to ground is 36 1/2" with P245 tires. When LOADED as detailed above, the rear feels firmer, has less body roll, and does not sag to excess like the OEM spring pack. Very satisfied with results. A very nice enhancement at a excellent price point. Kit is simple to install and should require no regular service/adjustment. 353831

  • Fit of SuperSprings SSR-114-47 Helper Springs on 2006 Ford F350 DRW
    I spoke with my SuperSprings representative, who confirms that the SumoSprings Custom Helper Spring Kit you referenced, part # SSR-114-47 will fit a 2006 Ford F350 DRW 4x4. Please keep in mind that this SumoSpring kit won't increase the capacity of your truck's suspension, and is meant to be used on suspensions that are in good repair.

  • Are SuperSprings Helper Springs Weight Rated Individually or In Pairs
    The capacity information listed for the SuperSprings SumoSprings is per axle, not per spring. For instance, the # SSR-114-47 lists a per pair capacity of 1500 lbs. Please be aware that using a suspension enhancement product like the # SSR-114-47 won't increase the weight bearing capabilities of your truck.

  • SumoSprings Suspension System Recommendation for 2000 Ford F-250 4x4
    I tend to recommend people go with the lighter duty SumoSprings since they will give the best ride quality loaded and unloaded. They still will give you the support you need but not at the cost of a decent ride. So I would recommend the # SSR-114-47 for your 2000 F-250 since it will give you 1,500 additional lbs of support.
