Features to know about

Stay Level and Confident Under Load: 2,800-lb Rear Suspension Support

Heavy trailers or bed loads can push your rear suspension down and throw off how your truck handles. These SumoSprings Solo helper springs add up to 2,800 lbs of support at 50-percent compression to keep your ride level and stable. They help your factory suspension carry the extra weight so your steering, braking, and headlight aim stay consistent when you’re towing or hauling.

Smooth Ride on Every Trip: Progressive Load Control

Every load feels different, so the springs adjust automatically. With lighter loads, they compress easily for soft engagement and a comfortable ride. As the weight increases, they get stiffer—compressing by as much as 80 percent—to provide strong support without bottoming out. This progressive action keeps you balanced and absorbs bumps so rough roads don’t beat you up.

Stay Steady in Crosswinds and Turns: Independent Spring Action

When a curve or crosswind pushes your vehicle off balance, each spring works on its own to keep both sides planted. That independent movement cuts down on sway and body roll, making cornering smoother and helping you stay in control even with uneven or off-center loads.

Built Tough for Real Conditions: Durable Microcellular Urethane

Designed for long life and steady performance, these microcellular urethane springs hold up in temperatures from -25 F to 200 F and resist damage from oil, road salt, and UV rays. They compress vertically with minimal side expansion, so they fit safely in tight spaces without rubbing on nearby parts. There’s no air pressure to check or tubing to run—just maintenance-free performance that keeps working trip after trip.

Quick Install with No Drilling

The helper springs are custom fitted for clean installation—no drilling required. You get two jounce-style springs that mount directly to your rear suspension so you can upgrade your load support in an afternoon using standard tools.

Specs

HIGHLIGHTS

Easy installation: Bolts directly onto existing frame without drilling or special tools.

2000 Nissan Leaf

Great product! Bought these for my 2000 7.3 f250. Didn't want something that is constantly active like ras or hellwig since my leaf springs are new and rated for 4k pounds. Installed these in 1 hr super simple only hard part was the factory bump stop on driver side was a pain. Didn't install the puck they give due to height of truck and I knew more or less at what point I wanted them engaging. I haul cattle to shows/ auctions or between pastures with my 24ft big bend and these things actually provided a smoother ride in my truck loaded then unloaded.they do a great job with the added support and are better than an overload spring with handling sway and providing a smooth ride loaded. Just wish I could use the 3k pound rated ones on this truck and my dually but doesn't fit if you have a gooseneck sadly so will probably have to go with timbs on the drw. Over all great product can't speak to longevity but solid for the time being. And customer service with this company is excellent if you have a question or problem they're on top of it...hope they pay them as well as the reputation they're building for them.

Working well. The truck rides better and hauls better since installing the SuperSprings.

by: Patrick 05/08/2023 One Year Later

The springs are great but I ordered the blue ones and received the yellow ones. They make the ride of the truck without a load in it rough. Roads around my area are not the greatest and these springs let you know it. Loaded down on the other hand is much improved. Over all good but will be switching to to the blue ones.

2020 Jeep Gladiator

This only pertains to the order, shipping speed, and install as I have not put a heavy load on these sumo Springs yet but I feel like that's a foregone conclusion based off the reviews already. The ordering process, the shipping, and the installation was unbelievably easy. I kept rereading the instructions thinking this can't be right because it was so simple. I looked at the YouTube video and realized it is that simple! So happy with the ordering process, the quality of the initial product I opened, and how simple it was to put on the jeep.

That is the beauty of SumoSprings! Super easy to install and once they're on you can forget they're there! Are you planning on towing something with your Jeep that you want extra support for?

Justin

9/1/2026

@ClaireH yes Ms Claire. I plan to put a truck camper on the Jeep (that weighs in the 500-1000 lbs range). My payload is 1700 lbs so I know a camper of the weight will be significant my truck. Already ordered a stiffer rear anti-sway bar as well.

Claire H.

9/2/2026

@Justin That sounds like a good plan! These SumoSprings plus the sway bar should be more than enough to handle the weight of your truck bed camper.

2013 Jeep Wrangler Unlimited

I put these on a 2013 Jeep JK (not lifted) that tows a 3000 lb trailer in rough terrain; Total game changer.

These replaced the anemic factory stops (which had completely disintegrated) and make it impossible to 'bottom out' on the dips and holes that use to beat up the suspension. I got nearly all of my vertical travel back and the vehicle now sits almost level under high tongue load.

They go on pretty easy. I suggest sliding in one side, and then using a wooden dowel and hammer to pop the other side in the stock receiver cup.

Highly recommended. These are a MUST if you are towing a trailer (with a medium sized SUV) of any significant weight or if you just want to be able to bounce hard without bottoming out your suspension. I am likely going to get the front suspension version now as well.
Wish I knew these existed sooner.

2025 Promaster 2500 159” wheelbase. Backed the van on couple 2” X 6 “ easier sliding under. Sprayed PB Blaster on top of bumper spring, using a 16” Channel Lock, easy off with the old. At that time I jacked the rear end to allow clearance. One side at a time. Took longer for set up then the job. I used the long bolt with two spacers. Have not drove yet, though looking for great results.

I put a set of 47s on my Silverado 1500 and towed my dump trailer that weighed 6000 pounds the way I had it loaded for 50 miles on all kinds of roads and it worked well. I didn’t use the spacers and the truck still rides like it did before the install.

Glad the Sumos are helping make your loads easier to tow!

by: Michael Batts 02/13/2026

Jeep Gladiator Mojave - swapped out the rear stock bump stops with these. High quality parts. Just jack up the truck enough to give you room to work with and put in your jack stands, no need to remove the wheels. I look forward to seeing how they do with towing! Hopefully I can update my review here afterwards. Check out the gap difference in the pictures. Should touch sooner during normal drive conditions and hopefully help reduce some trailer squat and help towing to be smoother.

Opted for the Blue 1000lb Sumo's w/spacer over the 1500lb Black ones. 1500 Silverado Max Tow & reduces squatting by 2" on a 1000lb+ tongue weight. Ride is still good, but you can feel the Sumo's engage over large dips or bumps which is not an issue for me.

by: Mike 07/21/2024

I got the springs installed last week and wanted to have a drive time before I wrote the review.

The height of the springs are perfect for my 2016 Tacoma, They keep the truck stable and nearly eliminate the body roll I had before installing them. I am heading to the mountains in a couple weeks, so I will update the review when I get back. That way I will know for sure the body roll is gone and the truck is stable on the winding mountain roads.

The springs installed in no time at all and since I had the rear end apart, I decided to add the leveling blocks at the same time, to keep the truck from squatting with the gear I haul around with me.

The guys at etrailer are great. And while I did not call them to discuss this item, they have been very helpful in the past with all my questions.

Below are pictures of before, a couple comparisons and after. Sorry if they come out sideways.

These Sumo Springs were a great addition to my Tacoma and well worth the money, IMHO.

The springs are working exactly as expect. I have need up to the mountains numerous times and to Monerary to the Sea Otter bike fest. They have reduced the body roll and helped keep the truck stable on the mountain roads or when loaded down for camping. Im very pleased I added these Sumo Springs to my Tacoma.

Definitely helps with squat on '24 F250 from boat trailer tongue weight. These do come with a plate to avoid uneven contact or wear.
I mounted using all spacers , stock is same unless speed bumps or large dips, u feel the stiffness/contact of sumo as expected. May take one spacer out .
Super easy to install , better than leaking bags.
Time will tell how they last

Glad to hear they are helping, Cory! If you are feeling them going over speed bumps, I think taking one of the spacers out is a good idea. Especially if that is happening when you are unloaded. Speaking of which, what are you towing?

2021 Nissan Titan

I had installed this model SumoSpring on my 2019 4Runner and had great results when towing the camper I had at the time. They greatly reduce the bounce when going over dips in the road at highway speeds. Now I have a 2021 Titan and a bigger heavier camper. I expect the same great results on the Titan. Installation was pretty straight forward and took about a half hour. The size difference between the OEM bump stops and the SumoSprings alone should give a better ride when towing my camper.

I bought a 2027 RAM 1500 to tow my 20' 5000lb Forest River. Easy to install. I did it in my driveway in 1.5hrs. Some of the bolts were dificult to access due to mufflers etc but a short wrench worked well. When I first hooked up my trailer I had 4" of rear bed setelment. With springs installed I had less than 2". Front lift is about 1/2". Did not compromise driving comfort and appeared to dampen trailer "flex" on RxR tracks etc. My right handled very well on a trip from S Florida to N Georgia on Interstates and secondary roads.

Had them installed and hooked up the trailer. Much improved support from sag due to tongue weight. Kept the vehicle very level to within 3/4" higher than front. Perfect rake and comfortable during unloaded or loaded driving. OEM bump stops really didn't do anything in comparison. Shop had to work a bit harder to get OEM stops off but install of these SomoSprinhs was simple. Glad I went this route.

Recommended SumoSprings for a 2001 Ford F-250 w/a In Bed Camper
Hey Kevan, thanks for all the information! Good call taking a hard pass on the Timbren's. The SumoSprings you referenced are the only thing I would recommend adding to your setup and coincidentally enough we have two sets that will work that have a 2,800 lbs capacity. Which ones you go with are going to be determined by whether or not your 2001 Ford F-250 is 2WD or 4WD. I have listed the options below: 2WD - SumoSprings Solo Custom Helper Springs item # SSR-114-54 4WD - SumoSprings Solo...

Will SumoSprings Solo Custom Helper Springs Fit 2000 Ford F-250 4WD With B8W Turnoverball
Hey Paul, welcome back! Yes, the SumoSprings Solo Custom Helper Springs # SS84VR will fit with your B&W Turnoverball installed. They're in roughly the same location but this replaces the factory bump stop and won't interfere with the gooseneck brackets. How did the SumoSprings work out on your F-350?

Suspension Enhancement for 2013 Ford F-350 Towing Dump Trailer/Skid Steer and Hauling In-Bed Camper
Hey Jason, welcome back! Assuming your F-350 is 2WD the SumoSprings Solo # SSR-114-54 you looked at will be the best option. If you have a 4WD model you need # SS84VR instead. These have enough capacity to handle your in-bed camper and keep you level while towing without overdoing it. Timbrens definitely have a tendency to make ride quality rougher since they have such a high capacity. If you liked the SumoSprings you had before in our Sierra 1500 you will be happy with these as well....

Recommended Rear Suspension Enhancement For Preventing Sway In 2016 Ford F-150 W/ Truck Bed Camper
For your 2016 Ford F-350 Diesel carrying a 1800lb truck bed camper and towing a 20' boat the correct SumoSprings would be the # SS84VR if your truck is 4WD or the # SSR-114-54 if your truck is 2WD. You will not need to add the springs to the front axle, just the rear.
