Front Suspension Support

A heavy front load can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front 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 rear axle, your rear 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 front 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 rear 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.

I love these Sumo “springs”. eTrailer never disappoints me. I had Stoops in Lafayette Indiana install them for me. I knew when I left the parking lot I was going to like them. Side to side sway is gone. Potholes are a slight bit harsher but is a small price to pay for the MUCH better handling I now have. 897720

2017 Ford F-250 Super Duty

Just got the sumosprings put on my 2017 f250, took it for a short drive the ride seemed better then it was with the factory bump stops. I also put on a set of timbern super duty bump stops earlier. I really like this product, truck rides nice and doesn’t sag when I hookup to my 14000 pd catering trailer when fully loaded. Both products well definitely make my truck ride better. 540066

Review from a similar SumoSprings Solo in Vehicle Suspension


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.

Sumo springs really helps on heavy load situations & helps the ride as well. Easy to install, does everything the company said & what I expected it to do. Etrailer ,their staff with their expertise & knowledge of the products as well as with tutorials , pictures & videos makes me come back to purchase products that they distribute. 698298

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

Review from a similar SumoSprings Solo in Vehicle Suspension


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

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

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

Review from a similar SumoSprings Solo in Vehicle Suspension


I installed both the front ( SSF-106-40-47) and rear (SSR-338-47) SumoSpring suspension enhancement devices on my 2015 Winnebago View which is on a Mercedes Benz Sprinter chassis. The vehicle is a bit top heavy and cross winds made the coach sway back and forth as did entering and leaving driveways and cornering on sharp curves. At times, this was scary and I was afraid it would lose control. I had a professional body shop install these for me for a very reasonable price, and upon leaving their shop, I felt the difference immediately. When I saw the original equipment pieces, I thought they were a joke. These new items touch the suspension at all times on the rear and are only 1/2" away from contact on the front. This has been a slightly over $400 investment in driving safety and is worth every cent. I literally said "WOW" out loud as I entered the freeway ramp: minimal sway with a good feeling of control. I highly recommend these devices. 524978

Review from a similar SumoSprings Solo in Vehicle Suspension


Installed these rear SSR-338-54 and front SSF-106-47 on my 2016 Mercedes Sprinter RV conversion (Thor Citation 24SR) Easy install. Did this myself and only had to jack up each side of the RV about 6 in. Didn't have to get the tires off the ground or removed the tires. The hardest part of the front where getting the bolts back in through the recessed hole in the suspension to bolt them in place. The rear locked right into place. Total install time about an hour. Only a short trip taken so far but sway seems to have been reduced. Will do a long trip soon to test out. 570539

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

Ask the Experts about this SuperSprings Vehicle Suspension

  • Will SumoSprings Lift the Front End of a 2017 Ford F-350
    Because the SumoSprings # SSF-111-54 will always be engaged on your 2017 Ford F-350 the stock suspension will not compress as much as it normally would. This will give you the feeling that there is lift though it isn't actually lifting anything it is just preventing the normal amount of stock suspension compression. You could go with a softer spring set, # SSF-111-40, which would allow the stock suspension to compress more than the heavier duty SumoSprings.

  • Suspension Enhancement that Can Fit 2006 Ford Super Duty with 6 inch Lift
    I have a solution for you, but SumoSprings does not have lift spacers like what are needed when installing their kits on lifted vehicles. So the best option for your 2006 Ford Super Duty would be Timbren kit part # TFRTT350F which gives you the same style of support but they offer spacer kits that you can use like with the # A25723-90AH00 for every inch of lift you have. Typically a 6 inch lift is really only a 4 lift of actual suspension increase so you'd need most likely a total of 8...

  • Recommended SumoSprings Front Helper Springs for RV on 2018 Ford E-450 Cutaway Van Chassis
    The only front SumoSpring options for the 2018 E-450 cutaway van chassis are the # SSF-106-47 which offers 1000 lbs of support or the # SSF-106-40 for 500 lbs of support. Since your RV likely has a cabover which adds weight to the front of the RV, I'd recommend going with the heavier-duty # SSF-106-47 option. The SumoSprings # SSF-111-54 you'd looked at are for a F-450 pickup, and wouldn't fit the Cutaway Van chassis your RV is built upon. I've linked to an installation video you...

  • Will SumoSprings Kit that Fits 2018 Ford F-250 Reduce Suspension Sag When Towing Fifth Wheel
    For your 2018 Ford F-250 the SumoSprings kit part # SSF-111-54 that you referenced would be engaged if the tow vehicle had 2 inches of suspension sag at the rear of it. The spring would begin to make contact and engage at around 1/2 inch of suspension compression which means this kit would give you excellent suspension support and greatly reduce the sag you have now. Handling and ride quality will also improve as well.

  • Recommended Sumo Springs Suspension Enhancement for 2020 Ford F250 Carrying Slide In Camper
    Unless you're using your truck to plow snow, most folks don't need suspension enhancement at the front. If you are pushing snow, the # SSF-111-54 with a 2800 lb capacity would work great. For the rears, I'd recommend # SSR-128-47-2 for 4 wheel drive trucks or # SSR-129-47-2 for 2 wheel drive trucks for a 4600 lb capacity. These will do a great job of handling any slide-in camper your F250 would be rated to carry. You can see product description videos for the items I recommended by clicking...
