Description:

With a cord of wood loaded in your payload and a burly winch strapped to the front bumper, your workhorse starts to sag like a twenty-year-old mattress. In the past, you'd have to rig up a complicated airbag system with hoses and compressors that need constant attention. Now, bolstering your suspension is a cinch with SumoSprings, the world's first "airless airbags".

The mad scientists over at SuperSprings cooked up a cutting-edge formula of closed-cell polyurethane foam and heavy-duty additives to form the spine of your springs. This blend gives your Sumo Springs the ability to compress up to 80% and expand up to 20%, delivering a progressive spring rate. Whether you're hauling a pile of bricks or a six-pack of chubby wrestlers, SumoSprings deliver exceptional ride quality with zero maintenance needed.

Custom engineered for a perfect fit, SumoSprings are available for the front and rear of your pickup, SUV or van. They're sturdy enough to handle harsh conditions, and most bolt directly into place with no drilling needed. Plus, they're backed by a limited lifetime warranty.

Perfect compromise

I did front and rear sumo springs. Since I only tow a trailer about 60 days a year i didn't want something that would compromise the ride the other 300 days a year. Dare I say it made the overall ride better because as a nice side benefit it seems to reduce body sway in turn. Use large pliers for leverage to twist them out. You also need a blunt pry bar to installation. You'll need an assistant too

Great product!! Fast shipping.

If you're thinking about purchasing this product do it!! It is everything it is build up to be. Installation takes less than 30 minutes and that was taking my time. I hauling 9000 pound trailer and now my truck only dips 1 inch. I have a slightly stiff ride without the trailer but nothing objectionable. The product seems to be well-made. I would definitely recommend it to anyone who wants to maintain ride height and stability. They shipped it fast and the price was the best I could find.

Long time sumo user

I have had sumo springs on my last 3 truck. I love them and they work great. This truck has the 5000 lb rated sumo springs, which are a little stiff, but I drive a truck not a Cadillac. They help control the porpoising when towing and eliminate a lot of the sag from my heavy goose neck trailer. Install was a pain because they fit a little tight, but other than that I highly recommend them.

Totally Awesome SumoSprings

Installed my SumoSprings in about 30 mins. really simple to install on my 2018 Colorado Z71, once I realized that I didn't even need to remove the factory bump stops ??. I quickly put them to work by hauling a full load 4 passengers & (2 yards of damp mulch) and the truck only dropped about 2" and the ride was amazing. Bumps and turns were no problem, even went over rough rail road tracks with ease and smoothly. Well worth the money!!! Best mod. yet! Definitely need this if you tow or haul!

Great springs for 2013 Fordf150 6.5 ft bed

I was a little skeptical at first but they came through with no problems. The installation was easy and they look great over the stock ones. The back end of the truck handles the roads better for hauling and for towing everything. The sumo springs product is great and at value costs savings over air bags. I do recommend this product to everyone.

sumo springs

It took longer to jack up the truck and get the wheels off than it did to install the springs. Haven't pulled my 5th wheel yet, but I'm sure it will be much better than bottoming out on the factory axle bumpers.

adjustable spacers

Easy install. I used the 1" spacer so the sumosprings would compress 1/2" when loaded. The springs keep from using the overloads and allow for a normal ride when I'm not towing my fifth wheel. the fifth wheel tongue weight is 1,400 lbs. Installed on 2018 F350

Very good for occasional heavy towing

I tow a 24' covered cargo trailer with my 2016 Silverado LTZ 4x4 Crew Cab w/trailer pkg. Empty, tongue weight of the trailer is around 400 lbs, loaded the tongue weight is around 800 lbs. The Sumo's help stabilize the back of the truck and keep it from 'bouncing' when hauling the trailer, especially when empty. If I were hauling the trailer on a more regular basis, I would probably install a set of air bags on rear axle in order to better 'level' the truck (front to back).

You probably only need the basic/blue model.

The Autoanything website doesn't say this. It isn't even on the supersprings website. The only place it is is on the back of the installation instructions - hidden in a small font among a bunch of photos of the product installed on other vehicles. But the 1500 and 2800lb models (black and yellow) are are only intended for applications with a constantly loaded commercial applications.

SumoSprings

So much better than changing the coils. The Fab Four bumper & winch did not drop the front very much, but it made the front more bouncy. Tried the SumoSprings & am amazed

2017 Tundra sumospring

Very easy to install on my Tundra. I have not loaded it so I cannot comment on how it works with a load. I do not notice any difference in how it rides. The spring sits about 1/2 inch from the frame with no load. Looks like a high quality product.

Work great but took some work to install

I put these on to fix clunking on the up travel of my cranked Silverado. They work amazing, my truck is quiet as a mouse now. But the gm engineers put tabs where the bumpstops are..took some work to get them in but I also didn't take off the wheel.. well worth it for sure. They help close the bumpstop gap on a tb cranked front end since they are an inch longer than stock

Good for Sprinter

Haven't had it out in the wind yet but they do seem to stabilize the ride a bit more without making it stiff or harsh. Read lots of positive reviews and have had the rears installed for 1.5 years. Figured it was time for the fronts.

Improved Ride!

I never thought this would work well. But I was wrong. My truck stays much level in the turns. Firm but not stiff and bouncy. Because they are in constant contact with the axle, my FOX shocks do not need to work as hard.

Sumosprings for Ford 550

The Sumosprings where so easy to install. The interior noise level in the motorhome dropped by 50%. It handled beyond my expectations. With just the back springs installed, it did not sway in the wind, corners, or driveways. It drove like a pickup truck. I am most impressed. I just bought the Sumosprings for the front.
