1,000-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
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.
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.

The sumo springs have been a very good addition to my Toyota Tacoma DCLB. I added a leaf and changed the shocks at the same time I added the sumo and the truck rides about a half inch above the sumo. I definitely can feel the sumo kick in when I compress the rear on bumps etc. non loaded. It’s not a bad thing but I don’t get the same travel but I also don’t slam on the bump stop. With that said, both driving with a loaded up truck and trailering has been much better than before. I can definitely tell the sumo doing its job. I towed a 4000lb boat the other day and the truck behaved perfectly.
After about a year of installing Sumo springs on my 2002 Tundra, I am still quite pleased. I have driven about 15K miles with them in and while pulling a 2 axle travel trailer with about 600 pounds of tongue weight with weight distributing hitch plus another 500+ pounds of stuff in the back of the truck. Much improved ride and handling. Cheap money well spent.
The massive ride feel improvement, I have a topper and drawers in the rear of my Tacoma. With the SumoSprings and medium-duty Old Man Emu leaf springs, the truck does not feel any hint of bucking or kicking anymore.
Easy to install. One easy hour and did not take tires off.

John - - 08/30/2022Great product and arrived early. Did have to enlarge the holes on my stock base plates to accommodate the slightly larger u-bolts. Included instructions made the install very easy.
Instructions were adequate. installer has to contribute to the outcome with bolt cleaning, match marking axle saddle and finding out "u" bolt torque value.
I think the mount should be radiused where the "u" bolt contacts it as opposed to the square edge. Was unnecessary to jack up truck to get clearance to screw on spring, I put a wood between frame and leaf and raised the box 1/2" with a wedge.
I got the ride height I was looking for, the blue springs are very close to offsetting trailer tounge weight allowing for a bit of takeup with my Andersen hitch.
Barely noticeable change in unloaded rear end stiffness.
Absolutely love these! Had them on my 2004 Toyota Tundra for a year now and have been extremely impressed of how the truck handles with and without heavy loads. Worth every penny.
Gene - 11/07/2022While towing my 28' Lance trailer with my chevy 1500. These Sumosprings helped stop the porposing that only happened sometimes over our lousy California highways.
We installed these on our 2013 Toyota Tacoma in order to haul an in-bed camper across country and back. These SumoSprings were the perfect solution along with some new beefy AT tires to help support the weight of the camper and keep us moving with the right support and suspension we needed for the trip!
Very impressed. Stopped the Tacoma lean. Also helped with the trailer. I do use a distribution hitch I bought from etrailer. Just bought the sumo spring for other applications. Those little bitty factory bumps where junk. These help with lean, and off road hard bounce.They are great.
Made towing TT with my Toyota Tundra much better. My camper has a tongue weight over 900 pounds. Made bridge crossing and overpasses much smoother.
The trailering capability of my truck is much better. In tandem with a weight distribution hitch, the 6000# trailer rides very predictably and stays exactly on track.
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.
Sumo lift springs work GREAT. Easy to install and work as advertised.
Thanks so much for support of the product.
RECIEVED PRODUCT YESTERDAY prepared truck for spring installation cleaned threads on U bolts removed fasteners removed factory stops installed super springs both sides within an hour !!!
Adds enough to beef up rear suspension on my 8 Ft Tundra Bed to keep it from over squatting towing 8000lb camper. Pleased with the results. However wish they didn’t contact the frame when there’s no load on the Truck. Definitely preforming as advertised!
This product arrived quickly, was easy to install has worked great at firming up the back end of my rig, for pulling a small travel trailer. Very happy with the product and service.
I installed these in my 2015 Toyota tacoma, they were simple to install and were a good additionon to my stock suspension. Great product ,great design,good investment for any truck needing just a little help in the suspension area.

Great product and easy to install on my Tacoma. Now able to tow my boat and RV with a more level ride and no more bottoming out! Buy these!
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!
Randy M - 03/12/2018Couldn’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.
Ordering from etrailer was easy and efficient. Install of the Sumo spring helpers was easy and even though I have not pulled my trailer yet the ride without the trailer has been great. I am sure once I hook up to my trailer everything will be good.
Thy work good, still have good ride for a Tacoma, carries good, more weight, no problem. Thanks
Hugh - 10/02/2022Love these springs on my 06 Tundra. They definitely help with my camper, and reduce the sag. However! I noticed that when compressed, they are compressing at an angle...the springs are sitting at an angle, rather than compressing straight down. Best I can tell, I Have them installed straight up and down. Any tips?
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.
