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.

We pull an off-road teardrop camper with our 2013 Toyota Tacoma and were looking for a little help with the rear end sag when we have that hitched plus putting some weight in the back of the truck (firewood, water, etc). Our Tacoma is lifted (2.5") but the lift kept the stock springs with an added Deaver leaf to help with the notoriously soft Toyota springs. However, with the shell and ~300 pounds of weight in the back, it still sagged, especially with another 250 lbs of tongue weight from the trailer. The Sumos have eliminated that sag, even with bigger loads in the bed, eliminated body roll (also notoriously bad with Tacomas) and didn't destroy the ride for day to day driving. There might be a slight bit more stiffness when hitting speed bumps, but definitely not bad at all. If anything, I would say it IMPROVED the ride and handling. The springs themselves were simple to install, less than half an hour start to finish. Some reviews have said they were bumping the frame after installing but we had about 1/2" gap on both sides. The only "specialty" tool would be a torque wrench capable of 90 lbs to get it to spec. We considered Firestone air bags but after talking with the reps at e-trailer, we decided on these and couldn't be happier. Reasonably priced (half the price of air bags), no maintenance, great customer service...can't argue with anything at all.

One year and working better than I imagined it would. Carrying loads in my Tacoma is no longer an exercise in fear and my shocks are way happier happier with a little help!

2015 Nissan Frontier

2015 Frontier Crew cab Desert Runner (purchased the yellow Sumo Springs). Easiest install ever! 18mm deep socket and long breaker bar for breaking nuts loose. Removed factory bumpstop, install sumo bracket and retighten U bolts to 58 foot pounds. After installing both brackets, lifted back of truck up 4 inches to install sumo spring with blue lock tight on bracket bolt, tighten sumo spring onto bracket and lowered truck off the jack. Overall it raised the back of my truck bed 1 inch. Ride is stiffer with no bed roll in the turns. Loaded my 24 foot travel trailer with load leveler- equalizer bars and gained 3 inches (less “squat”.) Truck is level now vs nose high (without the sumo springs). Definitely an upgrade that was needed in 2015 when I first bought the truck!!!

2014 Nissan Frontier

While I’m a fan of the folks at etrailer this purchase was a disappointment. Neat concept but didn’t work out for me. First off, after installed the ride in the truck was unbearable. I had them installed for only 3 weeks and could not wait to have them taken off. Never got to tow with them as the ride was that bad. When they took them off, the bolt up through the middle broke right off. I guess that’s how tight they were between the leaf spring and where the bump stop was. Shame though, I was really looking forward to having a better towing experience.

Thank you for your feedback. You might want to consider an air bag system like part # F2558
Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle

for the 2104 Nissan Frontier. It has an adjustable PSI from 5 to 100 which would give a smoother ride.

2009 Tacoma Offroad TRD DCSB Needed to correct squatting under load, and when towing small travel trailer. Install was easy and straight forward. Stock U-bolt nuts use 19 mm deep well sockets for removal and replacement. Sumo spring required jacking up the frame a couple of inches to allow install above leaf springs. Torque nuts to 90 ft-lbs. Need to re-torque after 500 miles. Highly recommend.

Couldn’t decide between the blue and yellow springs, bought both and switch them out when I need to haul my 5500lb trailer. I have a friend with the same truck (tundra) and he got airbags. The ride in his truck is terrible when not loaded down. The yellow springs are great for towing and the blue give you a better ride, no sag when loaded down.

After I’ve installed a Decked system and an ARE cap I felt my truck saggy, driving on a pronounced curve I didn’t even feel safe...

It was very easy to install. So far, I haven’t driven my truck because they were delivered yesterday and I installed them last night after work. The installation took about 45 minutes including reading the instructions. After I removed the jack, I noticed the bed was sitting a bit higher. I will be hauling my dump trailer with a full load to the dump tomorrow so I guess we’ll see if it makes a difference. I’m sure it will!

I've had these for 1 year now for my 2016 Tundra and they are exactly what I needed!!! I couldn't be happier! Prior to purchasing and installing these, when I towed my 2 horses with my 2 horse slant bumper pull trailer, I was concerned about cargo weight in the bed of my truck so I was limited to gear I could bring camping and hunting season with my truck. Since adding these I can pull the horses and load my truck bed to the max including horse feed, hunting gear, coolers with food you name it and my truck doesn't even squat a bit! The ride is great with a load or without and my performance off road is still fine too! These proved to be a great solution to my needs and frankly better than pricey air bags.


Comments
Were glad to hear that youre pleased with your purchase. Please keep in mind that the Sumo Springs product will not increase the capacity of your rear truck axle. The tongue weight of the trailer plus the weight of the cargo carried should not exceed the trucks rear axle capacity.

Great product. Wanted to stabilize my 2011 Tundra while carrying our pop up camper and accessories. Carried the load and leveled perfectly. I was concerned the sumo springs would stiffen the ride while unloaded but don’t notice anything. Ease of installing was main reason I chose these over other stabilizing products. Would highly recommend especially if you own a 1/2 ton vehicle

These sumo springs are a life saver. After a year they still have the same feel and have not deteriorated at all. I tow my camper and they keep my truck level, it’s a huge improvement over stock. Just the safety aspect alone is worth the minimal investment. For the price, you can’t beat them. 2011 Tundra with ladder racks and tool box’s. 800lbs in the bed at all times and a 7,500 lb caper on the weekends.

Toyota Tacoma

When we bought the pop-up camper for our Tacoma we knew we needed to improve the rear suspension. Many friends have used airbags, but those require frequent monitoring and adjustment, which we wanted to avoid if possible. Etrailer has a selection of Sumo Springs, and we chose a type that suited our situation. We installed them ourselves pretty easily. We enjoyed a long camping season with the pop-up and the Sumos on the truck, over all kinds of roads. The handling and the ride were great, and there was no need for maintenance. Now, with the pop-up off the truck for the winter, we're still enjoying how smooth the truck rides. Glad we got the Sumo Springs!

I just received and installed my sumospring on my 2010 tacoma 4x4 and am very pleased. Delivery was right on time. I've been pulling a 16 foot trailer with it and it would squat 4 to 5 inches. Now it only drops 1/2 to 1 inch and rides great. Thank you sumo people!!!

2010 Tundra 1. These springs are truly for heavy duty application, even when towing the 6000 lb. trailer, the ride is rough; every pothole and bump is felt like it's hitting the frame. 2. Easy application 3. Super Springs, direct customer service, awesome! Exchanged them for the lighter duty after conversing with rep. he recommended the blue 40 series light duty given the weight of the trailer and using a distribution hitch. 4. Way more economical with regards to price direct from Super Springs and will exchange them should you need to. Super Springs great; trailer not so much.

    For your 2008 Toyota Tundra, between the SumoSprings Solo Custom Helper Springs # SSR-610-54 and the Roadmaster Active Suspension (RAS) Custom Leaf Spring Enhancement Kit # RAS4611TD, the better overall system is the RAS # RAS4611TD.

    The SumoSprings Solo Custom Helper Springs # SSR-610-47 with a capacity of 1500-lbs will be a good choice since that camper is really only going to have a tongue weight of around 240-lbs maximum. If you're also carrying loads in the truck bed, these will give you the additional support you need.

    I'm really glad you asked because we only have one confirmed fit for the Pro-4x model.

It will not change the factory ride when not hauling a load, but will engage as needed for payload and towing.

  • Should SumoSprings Have Preload With Vehicle Unloaded
    According to the folks at SuperSprings, there should be a 1/2 to 1-1/2 inches of preload on an unloaded vehicle, so its likely that the suspension on your truck has worn to a small degree over the years. SuperSprings tells me that if the unloaded ride is more firm than you'd like, it's perfectly acceptable to trim a half inch or so from the springs. Doing so will not cause any harm to the springs and you'll get a less firm ride when the vehicle is unloaded. This won't affect the loaded...

The dry tongue weight for your travel trailer is listed at around 350 lbs, so when it's loaded and ready to toy it'll still be well under 1000 lbs. I've linked to a product description video for the SumoSprings.

  • Recommended Rear Suspension Enhancement For 2007 Nissan Titan Towing 8000lb Boat Trailer
    The SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-610-54 you were looking at would be a great maintenance free option to support the rear suspension of your 2007 Nissan Titan when towing your 8000lb boat trailer. The # SSR-610-54 has a 2800lb load rating and since you are only have 750lbs tongue weight this kit would offer plenty of support. The # SSR-610-54 will not affect the unloaded ride quality of your Titan as they are a progressive spring that only stiffens up when...

  • Recommended Suspension Enhancement for a Lifted 2011 Toyota Tundra
    This will depend on how your 2011 Toyota Tundra was lifted. If it was a body/frame lift, then the SumoSprings # SSR-610-54 will work. This style of lift does not affect the suspension and basically keeps it stock, for the lack of a better word. However, if it was a suspension lift that was done, then they will not fit. This style of lift creates too much of a gap for the # SSR-610-54 to supply any kind of support. That being said, you are not completely out of luck with a suspension...

  • Correct Sumo Spring Fit for 2021 Toyota Tundra
    For the best ride quality, you'll want to try to match the weight capacity of the SumoSprings application you use to the amount of weight what you'll be towing/hauling will apply to the rear suspension. The tongue weight of your travel trailer will typically apply about 600-800 additional pounds to the rear suspension of your 2021 Tundra. If you don't haul anything heavy in the truck bed while you're towing, I'd recommend the SumoSprings # SSR-610-47 which would provide up to 1500 lbs...

  • Can the SuperSprings and SumoSprings Be Used Together On a 2007 Toyota Tundra
    I do have an option for you but the SuperSprings Custom Suspension Stabilizer part # SSA4 and SumoSprings Solo Custom Helper Springs part # SSR-610-40 cannot be used together on your 2007 Toyota Tundra as the SuperSprings block the u-bolts needed to attach the SumoSprings. If you were to remove the SuperSprings part # SSA4 and then install the SumoSprings part # SSR-610-40 you would not be gaining any support as they are only rated for 1,000 lbs and the SuperSprings are rated for 1,100...
