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.

2009 Toyota Tacoma

Purchased for a Tacoma 4 dr, long bed, with a fiberglass cap. I have the TSB/recall replacement spring pack. With this set up I had a decent ride, and better support over the OEM springs, but still see that the springs provided only minimal improvement when loading in the bed say 300-500#. If so loaded (camp gear, MC gear, 2-3 persons in cab) on moderate unpaved roads the OEM springs were at max load and had we too much frame sag. WITH the addition of the SumoSpring kit I found my truck when UNLOADED handled the same, but did have less body roll in the rear. At rest the frame rail is just touching the SumoSpring and wheel well to ground is 36 1/2" with P245 tires. When LOADED as detailed above, the rear feels firmer, has less body roll, and does not sag to excess like the OEM spring pack. Very satisfied with results. A very nice enhancement at a excellent price point. Kit is simple to install and should require no regular service/adjustment. 353831

Re levels the poor Tacoma leaf springs. But definitely stiffens the ride on the off-road Bilstein shocks. If you carry a reasonable amount of weighted recovery gear at all times like I do, these are worth adding to your suspension. I installed them in 20 minutes. 561552

I put these on a 2016 Tacoma Off Road that tows a 4000 lb travel trailer. They have little or no effect on the truck when empty, but limit the suspension travel with the 450 lb tongue weight of the trailer. I far prefer them to air bags, which ave always eventually leaked down. 439574

Fantastic. has no impact on ride with no weight in truck. I installed them on my Toyota Tundra 2007 following a frame replacement. they sit about 1-2 inches off so they do not engage until loaded. significant difference with any load over 500 lbs. easy to install. 722454

Product was delivered and was a breeze to install! A friend happened to be around when I got started and we had them both installed in less than 20 minutes with the help of a car lift available to us. Didn't quite raise the bed of the truck as far as I hoped it would, but still a great product! Guess that's just the Baja Edition? But did find out I might need different shocks so that will be my next step soon. 508762

Great product ! Does all it claims and more than i expected. I leave my 5th wheel hitch mounted yr. round and haul bins of sand when I plow in the winter, so it's helping all the time. I can see and feel a difference in hauling our 30 ftr. Doesn't change the ride at all like just about anything else you'd need to do to get the help these give you. Easy install too! 347625

Still goin strong. I’ve had numerous campers even a Tundra owner inquire about what I’ve done to level my truck for the load. It totally out does more springs! When and if they fatigue, I’ll buy em again.

These Sumo springs are just what I needed for my 2012 Nissan Frontier. We (wife and I) have a A-Liner camper. We have recently replaced torsion axle with a more robust one and also went from C range to D range tires. We needed something to reduce the sag of tongue load. I was unsure about which model to choose but after speaking with friendly, knowledgeable Customer service rep I was assured the 610-40 was the proper option. Test drive went extremely well. Only minimal drop in hitch and no adverse change in ride. Very pleased! Simple to install. 875495

I added these to my Tacoma. With the GFC camper, Solar panels, Marine battery and refrigerator in the back of the truck and the weight of the trailer tongue I gained over 2 inches of height in the back after adding the sumo springs. The body roll is much less now as well. The only dissappointment is not with etrailer or the Sumo Springs, it is with UPS. Initially they scheduled the delivery on Wednesday then changed it to Thursday. Thursday came in went and still didnt have it. Finally arrived on Friday. Thanks for the delay UPS. 862164

These overload bumps or jounce bumps or whatever you want to call them are excellent. Sumo made it easy to determine which version (type and size) i needed for my application. these have worked great at keeping the back end of my Tundra off the old bump stops when using for loads and towing. Would definitely recommend and buy again. One note would be that you do hit them when unloaded and running over medium bumps so the unloaded ride is a bit harsher but for the additional load stability it totally worth it. 787245

My Nissan frontier would ride on the bump blocks when loaded so I installed these sumo springs and I have been very happy. They have made my truck much more useful to me even when I am using it off road on our farm or pulling a trailer. I would recommend these to anyone who needs a little more support in the rear springs for heavy loads. The installation was very easy as my Nissan did not even require me to jack up the vehicle, I simply loosened the leaf spring U-bolts and installed the new Sumos. then I retorqued to the specified value on the U-bolts and that was it was very easy on my truck. Also the price was very reasonable for the value received, I will definitely shop at etrailer again. 736192

Bought them because if I loaded two dirtbikes in my Nissan Frontier, it would bottom out occasionally. 1 bike and the truck was fine. They are pretty good for two bikes loaded, but make the ride a bit rougher when the truck is empty. Since I only load two bikes twice a year, I think I would have been better off leaving it as it was, and drive slower those times. If you load down the truck once a month or more, get them. It does ride harsher but not extremely so, enough to jiggle the coffee in your hand when you are sipping it. 721007

Install was easy, air impact driver helped for sure. Firmer ride empty than expected, but not overly so. From watching videos and reading adds did not expect to notice difference unloaded. Loctite was dried up in tube, was in process of install when I realized that. The true test will come when loaded or RV trailed is being towed. 2005 toyota tacoma trd 680871

Toyota Tacoma 2011 4 door short box Sport Great product. Other reviews said that it was easy to install Ya right, It was easy to install to much of my dismay. When it is installed it said that you have some space between the leaf spring and the sumo spring I did not, it is in contact with the leaf spring on my truck at all times. The ride is a bit stiffer when empty but it gives the truck a little rake that I like. Now when I have about 700-1000 in the back I have no problem with sag and the truck rides smooth. If this Tacoma ever wears out I will put one of these on my next Tacoma. 635661

Great service and prompt delivery from etrailer. I haul a small backhoe on a trailer with my Nissan Titan. The SumoSprings solve the small amount of rear sag I experience when hauling but do not affect ride during everyday driving. The product is great and I would recommend them to anyone experiencing similar issues. My first purchase from etrailer has exceeded my expectations. I would recommend them as well. 604797

Truck type: 2008 Toyota Tacoma SR5 Prerunner 2 WD Installation: Easier than an oil change. Took me about 8 minutes per part. I lifted the truck's receiver hitch 3 or 4 cm before starting. 19mm deep socket was the only tool needed. Did not even remove the U-bolts, simply loosened, removed old OE rubber pyramid bump part, and replaced with the SumoSpring parts. Results: fender height was normally 36.5". With RV on at 400 pounds hitch weight, compression was 4" before SumoSpring. After install, compression is 1.5". Leveling problem solved. As for ride without RV, I found an old bumpy concrete street nearby, ride quieter and smoother. On corners, truck is more stable and does not rock as much due to "centrifugal force". Overall: I like what I'm seeing. Will write again once I road trip the RV. 574225

So far, so good. Installation on my 2014 Tacoma went very well. The truck now sits about 3/4" higher in back and feels a little firmer in the ride. I plan to hook up my RV trailer this week. It looks like these will work just fine to eliminate the "tail sag" that so many Tacoma owners report. 526827

Overall the product was very good and easy to install. I used red Loctite on all the hardware components and I have not had any issues. I will say the product helps to reduce sagging with heavier loads in the bed of the truck. The springs did increase the rear ride height to that of slightly higher than the front end. When the truck is unloaded the ride of the truck is a little more stiff than I prefer. I would buy this product again. 524478

    I think you're on the right track here, considering that you're not currently experiencing any adverse conditions when towing. Because of the tongue weight of the trailer and the additional weight of the ATV, I do recommend going with the Sumo Springs # SSR-610-47 over the # SSR-610-40 since they're going to provide you with the needed support when you've got the ATV in. Your tongue weight of 460-lbs is going to vary depending on how the trailer is loaded, so you could end up occasionally...

    The # SSR-610-40 is the light duty SumoSpring available for your 2010 Toyota Tundra. These will have 1,000 lbs of support whereas the # SSR-610-47 would be considered the heavy duty version and would add 1,500 lbs of support. For you I would go with the heavy duty version. You should not that suspension enhancement does not allow you to carry loads heavier than what the current vehicle capacity is. It just provides more support to allow you to carry your capacity as safely as possible.
