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.

38’ Total Length 8k+ lbs Dual Axle Travel Trailer (Tow Vehicle is a Chevrolet 1500 5.3L W/SumoSprings)
– Application: Extremely easy and most anyone with a bottle jack and simple ratchet can complete the install in 30 minutes to one hour.
– Ride/Comfort: A beyond noticeable difference in ‘chucking’ from rough roads, bridge seems, pot holes, railroad tracks, etc. sent to the tow vehicle (all but disappeared). The side to side is far better and taking on/off ramps keeps the trailer is far more stable. Any purposing from roadway variation is drastically reduced to a 1-2x and back to stable driving, extremely quickly and smoothly.
– Noticeable Change(s): The interior objects of the travel trailer stopped moving within the travel trailer and were left in the position where they were at the start of a trip (i.e. toothbrush in a cup in the bathroom never tipped on a 6 hour trip). Less wear/tear to travel trailer and travel trailer items.
– Cost Effective: The recent discount codes provided make the small overall investment a safety precaution for protecting the travel trailer springs/suspension and the tires (reduction in tire wear).
Overall, any future travel trailer purchases will have these installed as a must, as I have done with several tow vehicles over the past 10 years. The SumoSprings products have never failed me and are easy install items that are maintenance free. A great weapon in the arsenal for recreational vehicle travel for weekend warriors or long haul, over the road, individuals.

The Sumo Springs don’t fit my 2021 Jayco Jay Feather travel trailer due to leaf springs are offset from the frame. I understand that SuperSorings is aware of this. Hopefully they are working on a solution.

Truck rear sumo springs is set for contact under load. Much improvement with towing. Sumo spring on travel trailer with continuous contact seems to have a smoother ride. I’m pleased.
Charles Youngblood –
Install was easy and works Great.
Alan Hulsebus –
I installed both sides in 1 hour. My tow vehicle feels less bumps from the trailer bouncing. The trailer is much more stable in corners and quick lane changes.
John Miller –
Very easy to install and looks like a very well-made part…
David Tindell –

So far so good, I have not towed the trailer yet.
David Alari –
They Springs really stabilized the front of the vehicle. They were super easy to install and the installation instructions were right on the money.

I wanted to update what I said above about my 2021 JayFeather with offset leaf springs and frame. Super springs reached out and provided me with a solution with the adaptor plate. It’s been working very well for almost 2 years now. Great customer service!!
Chris Sedlak –
Super easy to install. I can already feel the difference.

Rarely have I had a product greatly exceed my expectations, but I was blown away by the difference these made on my travel trailer. Virtually eliminates sway and bounce over bridges. Highly recommend.

Great and prompt responses from SuperSprings! I did the install at the same time I was upgrading the equalizer with wet bolts and the CRE3000. The SumoSprings were super easy to install and I relocated the gas line with the supplied kit and fabbed up my own brackets to account for the frame/spring offset, only because there was no time to order before our first trip. These seem to have solved our issue with things in the camper being tossed about! We did a 560 mile round trip and the trailer handled amazingly better!

Very easy to install, only ran rv to get inspection but could tell rv ( 5th wheel ) wasn’t bouncing on bad roads
Douglas Olsen –
Installation was pretty easy. I had to add the offset plates on our rig. I had a problem with the self-tapping screws that came with the plates. I had two strip out and gave up on using them to secure the plates with. I ended up replacing all of the self-tapping screws with 3/8” Grade 8 bolts with self locking nuts.

Made HUGE difference while towing

Preformed we’ll above my expectations
John Frieden –
Excellent order processing. My order was shipped much sooner than estimated ship time when I placed the order.
Just completed an 800 mile round trip with my new SumoSprings installed on my trailer. The improvement in ride and towing experience is remarkable. This is the best modification to my trailer yet. If I buy another trailer SumoSprings will be the first thing I install.
Steve Paraska –
Best upgrade I have ever done. Can’t believe how much better it tows now
Jesse Case –
Little tricky on port side of trailer as brake wires needed to be moved. Directions bit tricky to figure out regarding the spacers. I did call in and got some input from a tech guy at SUMO Springs
Nels Prario –
Arrived quickly. Installed easily. Have not driven with them yet.
John Frieden –
I installed a set on each axel of my travel trailer, the improvement to the ride is amazing. It smoothed out the porpoising when hitting big bumps and rough roads.
MARK STEINER –
They worked as designed.
John Arvin –
I purchased Supersprings for my van and my camper. The difference in the ride has been very noticable. I highly recommend this company’s products based on my experience.
