backed by a lifetime guarantee
Trailer SumoSprings® utilize the same micro-cellular air springs as SumoSprings. They mount above trailer leaf spring assemblies and create a cushion between the axle and trailer frame. Trailer SumoSprings reduce wear and tear on body-frames, windows, doors, closets, mounted TV’s, and other components by minimizing bounce, hop, and sway associated with most tow-able RV’s. Reduced sway and bounce in the trailer results in increased driver control, ride comfort, reduced maintenance costs, and reduced overall cost of trailer ownership. Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles—proof of the craftsmanship that goes into every piece.

Easy installation.

We watched the SuperSprings video “Trailer SumoSprings reduce G-force vibration | Navistar Proving Grounds”. From that video we knew we had to have a set of SumoSprings on our 5th wheel. We recently installed a set of TSS-107-47 SumoSprings on our 2022 Keystone Montana. This installation was very easy taking less than two hours for both axles. The SumoSpring kit had all we needed for each axle – springs, mounting brackets, and hardware. The results? Amazing! Our first 1,000 miles had rough roads. No longer are goods thrown around the 5th wheel. As an added benefit, the truck ride is improved. The up and down shock from the 5th wheel is substantially reduced and doesn’t transfer into the cab. Excellent engineering and knowing the SumoSprings will help protect our RV investment.

Really took a lot of the excessive bounce out of my heavy Northpoint 377RLBH, certainly smooths out the ride.

My friend who has the same 43 ft. 5th wheel said these were a must to have. He helped me install them & we have traveled approximately 500 miles so far on our 2 month trip. Have noticed a big difference.

Dylan Lindsey –
Absolutely Amazing!!!!!!!!! Couldn’t believe how much better the truck rides. Makes my daily commute of 250 miles so much more enjoyable. The sumo spring are the best money I have spent so far on this truck and I have over $25,000 in upgrades on my truck. Honestly I have been telling everyone about them! Thank you for a great product and excellent customer service!! Any wait to put them on my travel trailer!

Gives the trailer a smooth ride
Robert Goodsell –
After using Timbrens for 2 years what a difference! We had the Timbrens for a couple of years and the original set was way to hard of a ride. The Microwave almost fell out of the cabinet. They sent a second set of lighter springs. Still to rough of a ride. After removing these, we went a year without any helpers.
This year I decided to try the Sumo Springs. What a difference in the ride and handling. I would recommend Sumo Springs to any motorhome owner. The ride is firm but not harsh. I wish we would have installed Sumo’s in the first place.
CHRISTOPHER DEWSON –
Really smoothed out the ride and more stable when parked.
Scot Lowery –
Order arrived quickly. Installation instructions were clear, and install was easy. I haven’t been able to evaluate the spring’s effectiveness yet.
MEL FERGUSON (verified owner) –
Installed the Sumo spring kit on the twin axle 5th wheel. Easily installed and seem to work very well on the 11K mile trip from WI to AK and back this last summer. I did notice less chucking in the F350 dually
Douglas Dillon –
Very happy with them and ease of installment
Boyd Sherk –
The kits were very easy to install. I used 2 spacers per spring to get proper fitment for the 6 1/2″ I had between the spring plate and the frame.
Denise Reiling –
Fantastic customer service and excellent product. Definitely can tell a difference.
John Doyle –
They stopped a lot of body roll and reduced sway from passing 18 wheelers. Interior vibration seem less. Installation was fast and simple.
Paul Bell –
Easy install, no harsh bottoming out, recommended!!
Paul Motter –
I installed the sumo springs in Nov of 2023. We recently were able to test them out on our departure from Key West, Fla. to North Fl. There was a very much better ride. Very nice!!!
Thank you supersprings. I highly recommend these. Anything you can do for these frames are an upgrade.
Edward Weiss –
