Specs:
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.
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.

2,800-lb Capacity. Upgrade your vehicle'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.Senior citizen Installed in 30 mins on a 2022 f250 that hauls a 5th wheel. If I can do it must be an easy install. Use only one 1/2” spacer. Will test out in the coming weeks.
Super easy to install, and is a perfect fitting, direct replacement of OEM hardware. Half an hour, and done. Don’t forget to torque fasteners properly, and use Type-E torque seal/mark, to do it like a pro.
After much research, I opted for Sumo Springs for my 20 Superduty F350 4x4. Honestly I hadn't towed my 20,000 lb loaded weight 5th wheel Momentum too much without them on and even on rough roads I've never bottomed out my truck. They were very easy to install.
Easy installation, however the 2 puck spacers that touch the frame had to be ground down to fit my 2015 F250 frame. The inside portion of the frame has a rounded flange that rolls toward the ground, this is why I had to ground the puck spacers. Otherwise installation was a breeze and they work really well. Definitely reduce sway and sag in my work truck when fully loaded unlike the OE parts. The loaded photo is our truck bed fully loaded with about 2700 lbs in the bed and a trailer attached to the bumper.
I purchased a set of the SumoSprings for my 2018 F-250 about a year ago. We had purchased a new fifth wheel, and although it towed great, the rear of my truck squatted about 3.5-4” when we were loaded for camping. After installing the SumoSprings—which was a very easy project—the rear of our truck only dropped 1.5” when loaded on the hitch. Plus, the ride was much smoother than before! When not towing, the SumoSprings do not affect the ride quality of our truck at all. Great investment for anyone who wants to improve ride quality and towing capability!
Fast delivery and an easy install. I haven’t tried them with a load yet but, they seem perfect for helping to stabilize my truck when carrying my truck camper. They shouldn’t affect the ride when lightly loaded.
This is the 3rd vehicle I have installed Sumo Springs and this Specific application did not disappoint. The installation was so simple and they fit perfectly. I purchased these for my 2019 F250 so I did'nt have to worry about sag when towing my fifth wheel and again they worked as designed. My truck would sag around 3 inches in stock form with the fifth wheel hooked up but after installing Sumos the truck dropped 1 1/2 inches. A noticeable difference. I opted to leave a 1/2 inch space from the bottom of the Sumos to the axle as to have a little less engagement. Ordering from etrailer was easy and shipping was fast.
great product, i've used air bags in the past and these are the best of both worlds . I pull a 30' enclosed trailer on a 21'f250 crew cab
I’m sold, even if I was buying a new truck I would put them on rite away. Noticeable better ride and load handling.
My second set of these and so easy to install. Works perfectly to prevent sagging and keep under better control.
Make sure the UPS tracking number is obvious when you follow your original shipment email, its hard to back track your package. I give a 5 on getting the part and a 1 on the ease of tracking your order.
Installed them on my 2019 F250 liked the fact it didn’t change my unloaded ride, Once my 5th wheel with a 2500lb weight was hitched the truck lowered 2” make the truck level. The ride was very good while towing. I’m very happy with this purchase.
Works as designed. No sqat when 5th wheel is hooked to truck. Highly recommend!!
I have had them one year with no problems. They support the truck and we're easy to install.
these made a huge difference to the trucks carrying capacity, were very easy to install, and only stiffened the ride moderately. I'm very pleased.
They work great. More stability when to wing.
I bought these when I had a 27' TT. They worked perfect. I recently upgraded to a 40' 5er. They still handle the load very well. However, not being able to adjust the ride height to give the truck a more level stance will have me installing bags. I would highly recommend these for a smaller load like a TT.
I will say that the ride did stay like factory with out a load on them. This was very nice. Also, with a load the truck was very stable going down the road.
Best thing I've added to my F250. Truck sits nice and level with my trailers attached. Rides great with them connected too.
Very easy to install (15 min. each side) and worked exactly as advertised, 5th wheel has a 2800 lb tongue wt. and my 2020 F250 rode fairly level with only one shim, I may add the second to see how that levels it a bit more. Etrailer shipped the day I ordered and I received it a day before I thought I would, very good customer service, and good product videos and information!
So far so good. Very easy to install with basic hand tools. I did have to use an impact wrench to remove the oem bumper brackets as they were on very tight. Did not give 5 stars as I need to put 3000-4000 pounds in the back of the truck to see these springs take some weight.
I received my order today had them installed in less than a half an hour looks great I would say it’s three times the size of the original ones should be no more sag.
Product was easy to install. Product tighten up the suspension on my 2019 F-250. Made hauling my Lance Truck Camper more enjoyable.
Although I have not installed them yet, my experience etrailer is 5 star. I had a question before I ordered them and customer service assured me it would fit. The email I received with the names of people involved in getting my order shipped made it personal.
Thank you
Got the Sumo Springs for my 2020 Super Duty, and installed them today. Easy installation and perfect fit. Can't wait to hook up the fifth wheel.
