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.

Sumo springs helped handle the weight of my camp trailer, I would recommend them for a Nissan owner

One of several purchases from etrailer and all have been positive. The Springs got here today as promised and were what I ordered. Jacked the Titan up one side at a time, secured it with jack , brakes, jack stand. Removed tire and removed the old stop. installed the new sumo springs that were somewhat larger than the oem and reinstalled the tire etc. Did the other side and was done in about 30 minutes. Looking for great service from this product and see no problem. Just what I was looking for. Thanks etrailer!

Excellent !! Install took about a half hour and took a test drive with my trailer attached, and a noticeable difference, no noticeable sag on my truck and felt very secure.
And etrailer was very fast to ship, ordered Monday and was here by Thursday! Thanks again for another great product and fast shipping

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.



by:

Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs



by:

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.



by:

I originally purchased the yellow sumo for additional support when hauling a small trailer or taking trash to the dump so I wouldn’t strain the vehicles suspension that I just replaced . I also never like to see a truck squat . Yellows were too stiff when unloaded so I got these blues sumo and it was a great decision . The ride type is back to original “comfortable” and the sumo still provides great handling when cornering reducing body sway / shock absorbing bumps. A good investment !



by:

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:

I used the Sumo spring with the RAS system. I remove the pump stops and installed the sumo(without spacer) so the axle would be one inch from sumo so the RAS does the work when not pulling trailer and sumo sumos are activated with pulling the camper. The stability it created on highway and back winding roads was really great. Feels like a totally different truck when loaded up. The RAS came with an offset spacer to move the bump stop in a better place but I didn’t need it because the bracket with the sumo springs moved the unit back and in and had plenty of clearance for the RAC system. In total they only took15 minutes each side to install once the truck was up and the tires were off. The sumo spring and RAS together were amazing and would recommend them to anyone with an F150 that need a little more support near the bumper.

These were shipped to me mid-trip so I had a good chance to do a before and after with same loads/ same roads for 3100 miles. They were easy to install (in my daughters driveway) in about an hour with one reluctant bolt in the original bump stop. I did not install the hard spacer, I figured I’d add it later if needed. I was able to do the install w/o jacking up the whole truck using a 1 1/2 ton jack under the hitch receiver w/ a jackstand next to it. I needed just a few inches as there’s lots of room under the stock height truck (I was lying on a piece of cardboard). The helper springs didn’t quite touch the axle when the jack was removed. When I first drove it in town with the Sumo’s on it they were not really noticeable. When loaded up with my 22’ Livin’ Lite Axxess trailer (4300lbs with 650lb hitch weight) the rear end would squish into the overload springs a good 3/4” but the truck was about level w/o rear end sag.
Driving home over many of the same roads I noticed it was better over railroad crossings and rhythmic bumps on the highway that previously pitched it fore and aft. The trucks manners were much better overall during big hits (like hitting a curb- yup) and pulling off-highway. The trailer is low so it doesn’t go very far off road so I can’t report on that.
Overall for ease of ordering, of install, simple usage w/o need of airlines and effective control of the rearend of the truck and the trailer I feel they deserve the 5 stars.

I bought and installed the 1000lb Sumo Solo springs to help alleviate rear end squat on my 2024 GMC Canyon Denali when pulling my boat. My boat trailer has a long mono tongue with no weight distribution installed. The boat weighs in at about 5500lbs, the truck fender lip measures 38” high unloaded, once I dropped the hitch down on the ball and the Sumos picked up the load, the fenders measured 36.25” equating to an inch and 3/4 squat. Empty the Sumos have an apx gap of 7/8” above the frame rails. The Sumos were recommended over the Timbrens for my situation of infrequent towing with this truck and to maintain the best ride possible when not towing. So far my ride is virtually unchanged when empty and feels controlled when towing. Installation is straight forward but the instructions could be a little clearer with a diagram showing the intended location of the springs. Luckily an etrailer customer had already done the install and provided some pics so there was no question. I chose to remove the tires to have good access and I’d do it again this way. I supported the truck with a jack stand under the receiver. IMHO the proper method to locate the over frame upper clamp brackets is to push the forward clamp as far forward until it contacts the bed stiffener and you’ll be in the correct location then let all the hardware hang to position itself, tighten as required and enjoy.



by:

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:

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:

First, etrailer has always been awesome-unparalleled customer support and product selection. For the Sumo Springs, I’m conflicted on what to say. I think they work great. I have a Ram 1500 and I installed them to pull a larger travel trailer and they certainly took the sag out and leveled the truck. We did a trip from Maine around Lake Superior and they felt great.
The short story is that after some time probably 6 months they collapsed. That being said Sumo Springs was quick to replace them, but it was no fun reinstalling them. They blamed it on the cold weather, but hell, I live in Maine. We’ll see how this winter treats the new ones.



by:

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:

Big difference in pulling the rv. I have about 545 lbs of Tongue weight.The sumo springs help with the swaying.Thanks again.



by:

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.



by:

The Sumo Springs are probably the top purchase for my 5th wheel. Our ride is smooth and I believe it extends the life of my suspension. If you're going to RV full time, I would consider these a necessity. Put them on your RV and your truck. You'll be glad you did.



by:

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:

Gotta little 2000 ranger 4x4 that pulls my home made 5x10 off road camper.Was squating and bouncing pretty bad with the 25 year old factory springs.Got these and put them on in about 30 minutes without even jacking it up. Dropped the spare tire for a little more room under there. Was the most worried about the 25 year old rusty bolts holding my bump stops on. I sprayed PB blaster on them a couple of days and no problem, if you don't count the ratchet slipping off and causing me to rip a chunk of meat out of my 71 year old arm. Don't worry, all my projects have some of my DNA on them.Everything went great after that, easy peasy. Before you tighten everything up, make sure the bumper mounting bolt is lined up with the vehicle bump pad or the new bumper won't hit the center. Just finished the install haven't pulled my trailer around yet. I'll do that after the first aid on my arm.LOL.

  • Best SumoSprings For 2023 Nissan Titan
    Between the 1,500 lb SumoSprings # SS95GR and 1,000 lb SumoSprings # SS35GR that fit your 2023 Nissan Titan, the best option is the latter, the 1k springs: - SumoSprings Solo Custom Helper Springs # SS35GR The 1,000 lb capacity is more than enough support for the '23 Titan's suspension, and they aren't as dense as the 1,500 lb springs, which means they aren't going to be as stiff so you'll get a better ride.

  • Is There A Spacer Available For A SumoSprings Solo Helper Spring On A 2019 Nissan Titan
    As you mentioned your 2019 Nissan Titan being a work truck there will be another option, but there is no spacer available for the SumoSprings Solo Custom Helper Springs # SS95GR, unfortunately. With that said, as the # SS95GR is rated to 1,500 pounds of capacity, you may want to go with a higher rated product, like the Timbren Rear Suspension Enhancement System # TNRTTN. This will have a 6,000 pound capacity and will do a better job for getting rid of the sag, but I do have to mention...

  • Timbrens or SumoSprings for 2019 Nissan Titan
    Since Timbrens are notoriously harsher than SumoSprings and the truck will be unloaded for most of the year I would recommend the SumoSprings for your 2019 Nissan Titan with the part # SS95GR. This will give you the support you are looking for without destroying your unloaded ride quality.

  • Should There Be Space Between the Frame and Axle when Using the SuperSprings # SS95GR?
    The SumoSprings Solo Custom Helper Springs - Rear Axle # SS95GR is the exact same part as the SSR-621-47. Sometimes etrailer uses different part numbers than the manufacturer's part number. These springs are confirmed to fit your 2017 Nissan Titan SV. It is important to note, that when you install these SumoSprings, you need to remove the factory bump stops as outlined in the instructions. This is most likely causing the extra space between the axle and the frame. Once removed, there...

    The height of the SumoSrpings Solo Custom Helper Springs # SS95GR is 5-1/2 inches without the top bolt and 6-1/2 inches with the top bolt. I went ahead and attached a diagram of these dimensions to give you perspective. If you need the confirmation for a fit with your vehicle, I would be happy to assist you if you provide your year/make/model.

  • Timbrens or SumoSprings. Which One is Better for a 2020 Nissan Titan 4WD?
    I strongly recommend going with the SumoSprings Helper Springs item # SS95GR over Timbren's like item # TNRTTNB for your 4WD 2020 Nissan Titan. Both systems will support your rear end and keep your truck level while towing but you won't notice the SumoSprings when you are not towing. The Timbren's will be rough and stiffen up your suspension. You'll feel them going over every bump. I have linked a review video below.

  • Should I Use Timbren Or SumoSprings Suspension Enhancement On My 2020 Nissan Titan Pro-4X?
    You are on the right track in looking for jounce springs, as this will reduce your Titan's rear sag and also improve the overall handling of the truck while reducing body roll. Jounce springs are also very easy to install and require no maintenance, unlike air bags. When deciding between Sumo Springs and Timbren, it really comes down to how much weight you will be adding to the bed of your truck. It sounds like SumoSprings Solo Custom Helper Springs - Rear Axle # SS95GR is the kit for...
