Front Suspension Support

A heavy front load, such as a snowplow or a winch, 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.

Just had PEP boys install (it was 22 degrees outside) both front and rear.

This review will be duplicated for the rear as well.
Excellent, been meaning to purchase and install on my 2007 GMC 2500HD Classic.
My pickup is now my weekend drive for the toy stores (Lowes, Home Depot...)

Immediate improvement on handling, turning and stopping. Have not connected a trailer to it yet.

Previous experience with Summo on 2005 E450 Shuttle Bus and a 2018 Thor Axis 25.5 RV.

Still kicking it...



by:

Easy to install and fit as it should. There is a alignment pin that sticks up on the flat surface and lines up with a hole in the bump stop bracket on my GM truck. It would be nice if this alignment pin was longer as it barely catches in the hole since it is so short.

The Sumospring bump stops were too thick to easily install on my Silverado 3500 classic 2wd . The supplied lock nuts and washer also difficult to install in the tite spot they are located in. It was much easier to reuse original nuts. The test ride was satisfactory. Time will tell on their durability.

Installed these on my 2010 GMC 3500HD diesel, install was relatively easy, noticed handling improvement on the first corner pulling my 30' fifth wheel camper



by:

I think these work well , it has made the truck feel more stable when towing.

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:

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:

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:

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



by:

I installed the black Sumo Springs on a 2019 Toyota 4Runner. The fit was easy. Passenger side could be done without jacking the vehicle (although many folks on Youtube said they could not make the install and tighten). I used zip-ties to tie the brake sensor lines away from the pinch points. The Sumo springs are a great option. I tow a 3200# travel-trailer. The Sumos reduced sag at the hitch from 3-inches to one inch, and the wider contact points with the axle clearly provide more stability. I am 4000-miles into an out and back cross country camping trip. The ride while towing is tighter and gives more confidence. Glad I chose these over "air bags".

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.



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:

Towed my 12k fifth wheel with my '23 super duty once before purchasing these. Night and day difference! The springs reduced the side to side sway and wallowy ride. My initial tow it felt more like a bumper pull than fifth wheel, now back to feeling very stable. The truck still squats pretty good but not as much.



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.



by:

The parts are made with what appears to be a powder coat paint job.They all came packaged nicely and well protected. The instructions are clear, accurate and easy to follow. Mentioning that there is a left and a right assembly may be helpful to some. Mentioning "outboard" may be ovelooked by some. They installed easily. Removing the wheel gives you plenty of room for easy access. Once installed with my 4runner on the ground, the SumoSprings were resting on the frame. I do have a dog kennel and lots of training equipment that is loaded constantly. Hopefully these will help when I pull my RV. I did take it for a drive and it felt "firmer" more stable around sharp curves. I like them.



by:

This is the second pair if SumoSprings I have bought. The first pair of springs were Great coming my truck level with support trailering a 26 ft RV. My first truck was totaled last October by a bad driver.
I just bought enough pair SumoSpring in another truck to haul and support a big weight.
Thanks,
Bruce Forejt



by:

Installation was relatively easy and straightforward. I haven't noticed a huge difference in ride quality yet but I haven't towed anything since installing them. I will edit my review as soon as I am able to put the sumo springs under a heavier load or find the time to get off road.



by:

I waited until I could drive the MH to rate this purchase. They were super easy to install. This difference was subtle but noticeable. Less body roll in corners and in windy conditions. This also resulted in better steering and a more relaxed drive. Well worth it!



by:

I love my Ram, but I would white knuckle it while towing my travel trailer which is 3000 lbs. under my towing capacity. Well, I was skeptical that a $300 part could make a difference in the handling of my truck. But this has made a whole world of difference. No porpoising, minimal sway and NO white knuckles. And when I’m not towing, I don’t even know the springs are there. I highly recommend these helper springs!



by:

Together as a set of front and rear sumo springs and the Hellwig anti-swaybar the ride in my Leisure Travel van is like night and day, improvement and handling!



by:

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.



by:

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.

These work great for my 2014 Chevrolet Silverado 1500. I pull a 7,000 pound 30 foot Sportsmen RV with a bumper-hitch (heavy tounge-weight). I thought about replacing the leaf springs (way to expensive and difficult to install), but these work great! Under normal load, they are about a half-inch from the top of the axle, so they don't really affect the normal day to day suspension travel (allowing for the shocks and leaf springs to provide the support). My leaf springs are saggy, so it doesn't take a lot of weight to contact the Sumo's. (Also, I have Monroe load-level-load-assist nitrogen charged shocks...Which I highly recommend If you don't haul much weight or don't trailer, the Monroe's are good (awesome)enough without the Sumos). When the trailer rocks up and down after a bump, the Sumo's don't 'thud' when they contact the top of the axle. Smooth, and they reduce the body-roll (when under load) because they remain in constant contact with the top of the axle. Just unscrew the old bump-stops (with a bit of effort) and screw these right in. I would highly recommend! Make sure you get the blue ones identified for the 1500. not as stiff as the ones for the 2500, 3500. Do it!

  • Front SumoSprings Recommended for 2007 Silverado 3500 Classic With Heavy Slide In Truck Camper
    We typically only recommend front suspension enhancement products for vehicles with heavy brush guards/winches or snow plows, but with a heavy camper in your truck bed, using a front SumoSpring Solo application would be an excellent idea. You'll want to use part # SSF-201-47, which would absolutely reduce body roll in turns that can be caused by having a heavy slide in camper, especially if the camper is on the tall side.

  • Will the SumoSprings Custom Helper Springs Kit # SSF-201-47 Fix Damged Torsion Bars
    The SumoSprings Custom Helper Springs Kit # SSF-201-47 should only be used on a vehicle that has proper functioning suspension. If you have weak or damaged torsion springs I would recommend you have them replaced before you install this product. These would not fix the problem you have as they are only designed for additional support. Not to be used as a bandaid for damaged suspension. We do not have access to information on what the stock ride height would be for your truck.

  • Timbren Front and Rear Suspension Enhancement For a 1999 Chevrolet Silverado 1500
    The Timbren # TGMRCK15S have an 8,600lb capacity while the Timbren # TGMRCK25S only have a 6,000lb capacity. If your 1999 Chevrolet Silverado is only used for occasional heavy loads I would go with the 6,000lb kit otherwise the 8,600lb kit will provide you with the best support if you always have heavy loads. For the front we have the 2WD # TGMFK25S or 4WD # TGMFK15A Timbren springs. These are primarily best when using a snow plow as they have a very heavy 14,000lb capacity. The SumoSprings...

  • Recommended Front Suspension Enhancement for 2007 Chevy 2500 with Snow Plow
    For your heavy snowplow, I recommend the Timbren Front Suspension Enhancement System # TGMFK25S over the SumoSprings Solo Custom Helper Springs - Front Axle # SSF-201-47. The Timbren Aeon Rubber springs are simply rated for weights 7x larger and they work in the same way as the helper springs, yet offer more support on the front end, so that first inch gets more support and you don't feel the drop when raising your snow blade.

    I have a great suspension solution for you. While towing a trailer that weighs 17,000-20,000 pounds and other heavy setups on your 2009 GMC Sierra 2500HD, the Firestone Ride-Rite Air Helper Springs - Double Convoluted # F2250 will technically provide you with a bit of support on your rear axle.
