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.
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.
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.

After a year, very good suspension enhancement. The initial install was a pain only because I sheared the factory bolt in the original bump stop trying to remove it. Had to drill out and re-tap for new Sumo spring bolt.

They do a good job. After the install we brought home a ton of home heating pellets on our utility trailer. Barely any rear suspension drop at all. They're a simple part that's easy to install and they do the job. One tip tho, be sure to heat the old bolts to ease the removal of the original parts.

Used for '21 ford ranger for towing 5500lb travel trailer. Helps with squat and ride, good option. Didn't use 1/2 puck, but will need to go back and add to further reduce squat.

Put on Sumo springs helper springs on my 2022 Ford Ranger and it was easy to install. They work great on hitting any bumps and when pulling my travel trailer. Would recommend them for sure.

Factory bump stops too short with new leaf pack this solved the problem

2020 Ford Ranger
Works great on 2020 ford ranger. Left out the extra spacer because I don't want it riding on the leaf spring all the time. This gave it almost an inch clearance before the sumo touches and starts to help. That is what I wanted to not have it as stiff initially offroad, etc.

These were a great replacement for the included OEM bump stops that were basically worthless. I was able to max out towing capacity without blinding oncoming traffic. Handling is greatly enhanced while towing. Install was incredibly quick and easy by removing the wheels for direct access. Only drawback is unloaded ride is now a little harsh.

These are too stiff for a Ranger. Feels like driving around on your bumpstops.

I believe it’s going to be a great addition to my truck when pulling our RV. Looking forward to a smoother, more even ride. I left the 2x4 blocks in overnig8ht and drove around to ensure a good seat for the springs.

I installed Sumo Springs on our 06 Xterra right after we bought our Casita 17' trailer. The back of the X squatted a bit more than I liked. I had also noticed before some tendency to bottom out if the car was full of people and stuff. These ingenious devices are a perfect solution for me! They are about 3/4" clear of being engaged with the axle when unloaded, so the ride is not overly affected, but progressively take up some of the weight when the back end starts coming down with load. It now sits very nicely with the trailer connected, no weight distributing hitch and stuff in the back, and no more bottoming. We've put a good number of miles on the X in the last year, towing and not towing, and they are still doing the job.
I should note, the back of my Xterra is lifted about an inch with AAL springs. If that were not the case, the Sumo Springs would be engaged all the time. That will vary with vehicle.
I will also note that they are non-adjustable, unlike airbags. I kinda like that, I didn't want to mess with adjusting air pressure and such. But once they do start kicking in as one or both wheels travel, they do stiffen it up quite a bit. I mean, there's no way around that; you can't take load without stiffening the suspension. As such I think they inhibit upward axle articulation a bit when 4-wheeling, but for us that's not a big deal. Since they do not connect to the axle, they don't affect downward articulation at all.
The pics are shortly after installation, one with the car unloaded, and two with trailer and gear loaded up.

Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs
by: Dan08/01/2023
These Sumo Springs were easy to install, even for a 70 year old guy. I tow a 7,000lb camper and even tho I have a nice WDH I still had som sag on my Tundra. These helped level it out when towing and got rid of “some” of the bounce. They were really a godsend when I overloaded the bed with about 2,000lbs of pavers. That weight squished the Sumos significantly but the truck drove and rode great. Better and less expensive than air bags.
by: Kenneth02/22/2023
Gave it 5 because of ease of install - note they use SAE threads 9/16, truck frame and oem is metric 15mm wrench. Makes no difference but don't use oem nuts on spring. I installed all shims supplied and this left about 3/4" gap so hoing its the best for my needs. Easy to reduce if needed.
by: Thomas07/09/2022
The SumoSprings Solo came to the RV Resort today. I installed them on my Titan SV today in less than an hour. Only drove 10 miles with them and they are what I was looking for. In my opinion it was a needed upgrade and thumbs up!
by: Zach01/24/2024
While these worked great for the first few months and helped level the load, they have now become deformed and squished out of shape permanently. We have a slide in camper that is on the truck for only for trips otherwise the truck is unloaded and off the bumps. I did not expect them to deform so much, and so easily after only a year of use.
by: William01/13/2024
I have had these on my Jeep Gladiator for over a year now and I still like them. Sumo Springs really help with sag when towing my Scamp camper trailer and when the truck bed is loaded with stuff. When it is cold outside they are stiffer and I can feel when they hit the stops on hard bumps. Sumo Springs are a very easy overload spring option with factory lift.
by: Curt03/16/2024
Fairly simple to put on but need to work around the brake lines and bed cross beams. I haven’t tried it yet with weight. I have enclose pic of drivers side. Maybe can’t tell from the pic but there is space and flexibility around the lines around bolt.

- Is Part SS86MR The Same as SSR-141-47 For SumoSprings on 2019 Ford RangerThe two parts you mentioned are indeed the same; the SSR-141-47 is the SumoSprings Solo Custom Helper Springs - Rear Axle # SS86MR. The # SS86MR is just the part number we use for these SumoSprings on our site, but they are the 1,500 lb capacity SuomSprings that fit your 2019 Ford Ranger. We do have the 1,000 lb capacity SumoSprings that fit your '19 Ranger as well, which are the SumoSprings Solo Custom Helper Springs - Rear Axle # SS76MR.

view full answer... - Will Lower Rated Spring Bars Help With a Wiggly 2021 Ford Ranger Towing Wolf Pup CamperWhen it comes to weight distribution, tongue weight is the most important factor. In this case, it doesn't sound like the spring bars need to be swapped out. Although I don't know the exact model of your camper, the tongue weight is going to be 10-15% of the loaded weight of your Wolf Pup. It will also include the weight of any cargo behind the rear axle of your tow vehicle. The # FA94-02-0899 spring bars used on the Fastway e2 Weight Distribution w/ 2-Point Sway Control # FA94-00-0800...
view full answer... - Can SumoSprings Kit be Used with 2021 Ford Ranger with Weight Distribution SystemSuspension enhancement like the SumoSprings Kit part # SS76MR that fits your 2021 Ford Ranger will help with the porpoising that you are experiencing when towing. You will end up needing to use slightly less spring bar tension to compensate for fact you now basically have stiffer suspension. So that would mean lengthening the chains. We can't say by how much you'd lengthen it though.
view full answer... - How To Prevent Trailer Bounce While Towing with a 2021 Ford RangerA simple set of suspension enhancements should help tremendously with bounce while towing with a 2021 Ford Ranger. I recommend the SumoSprings Solo Custom Helper Springs part # SS76MR which provides a bit of cushion as well as support without sacrificing ride quality. They are also simple to install and cost effective. If you have issues with sag/squat or trailer sway then you can look into a weight distribution system but these require more setup each time and can restrict turning and...
view full answer... - 2021 Ford Ranger SumoSpring Recommendation for Towing a Trailer with Weight DistributionSince the only difference between the SumoSprings Solo Custom Helper Springs # SS76MR and # SS86MR is the weight rating (the former being 1,000 lbs and the latter being 1,500 lbs) I recommend going with the lighter option - part # SS76MR. It would be good to double check the weight rating for your weight distribution system (WDS) prior to swapping out your suspension enhancement. The Timbrens have been known to make the ride a bit more stiff but if your WDS is rated too high then that's...
view full answer... - Will Jounce-Style Springs Fit a 2021 Ford Ranger with Tremor PackageAccording to my research the SumoSprings Solo Custom Helper Springs # SS76MR will fit with the Tremor package on your 2021 Ford Ranger, but the Tremor model sits about 1" taller than the standard Ford Ranger so the SumoSprings may not end up engaging like they should. Since this is the case I recommend going with the Timbren Active Off-Road Bumpstops # T98FR instead and using the 1" Spacer # A25723-90AH00 to help take up that extra space, but you will need to pick up a longer M10 bolt...
