Sumo Springs

We have a 2019 Georgetown 36D7 (GT7 F53 frame) if you havent't heard of it.... that's ok, Forest River informed me only 15 were made ( wow I felt lucky), but I decided to install the sumo springs all the way around today (We purchesed them from e- trailer great people). Fronts were easy, the rears took more time, but got them on. tomarrow I will see if it was worth it and I will let you know.
Hopefully it will take care of that extrem sway.

I think you will enjoy them. Much less road vibration coming up into the unit as it is now sitting on those giant ďbagsĒ

Maybe only 15 36D7 were made in 2019, but there is plenty of 2020's and 2021' for sale.

On my 31L5 the Sumo springs took a lot of the sway out. Along with the CHF almost all sway is gone. I think you will be pleased with the Sumo's


HONDAMAN174 What giant "bags" are you talking about ?

The actual sumo spring- a synthetic air bag/spring. Itís just what I call them so others understand since you actually donít add air to them.

You will like them. I also installed a rear tracsteer, very little sway even with a 800# motorcycle on the rear.

Wow!! Talk about night and day! That is money well spent. It feels much tighter and almost eliminates that side to side rocking.
My wife was following me home and she said " now it looks like it won't tip over" - that sealed It!
We also have a steering stablizer that works well. Now looking forward to our trip to Anchor Down Campground in Tennesee next week. I might just add that 5 Star Tuner eveery one likes

I added sumo springs to the front of my 2016 Forester. The difference is amazing. It is one of the best upgrades I have done. Takes all the dipping and sway out. I have no other chassis upgrades. It does have rear airbags installed from manufacturer. I highly recommend them in the front. Install is a snap.. You will not be disappointed.

Thanks. That is what I was hoping to hear.

The front Sumo's look like they come in 500 and 1000 pound rating. Which one do you recommend?

UPDATE!!!
Took a 460 mile round trip to Danridge Tennesse ( Anchor Down Resort Campground, Highly recommend) from Virginia.
Not only did I install the sumo springs before we left, but I also installed the 5Star Tuner, all I can say is WOW what a difference it all made. Had very strong wind advisory going down and boy was it crazy, but those springs were outstanding- no more white knuckle driving! The 5 star tune was even better.
up hill I was not getting the high rev, but nice pulling shift points. All was worth every penny!

I had a 2018 31L5 that I installed the sumo's all around great investment. Made driving it a little easier. Wish FR would have it as an option or just put them on to begin with....LOL I know that will never happen.

Hey, I think I saw a Georgetown with that paint job here. We're leaving Anchor Down on Saturday.

Yeah, we left the FMCA campground just east of Cincinnati this past Saturday, I-71 to I-40. We hit the same winds, 25 MPH gusting to 50 MPH, most of the way here. I was very thankful I had gotten the Roadmaster supplemental 1 5/8" rear sway bar installed just before this trip.

My wife drives almost all the time and on our last trip a side gust actually caused me some concern as she was fighting the steering wheel for several seconds. This trip had far less sawing of the steering wheel and noticeably less swaying at any time.

We stopped at a rest area in, where else, Georgetown, KY for a dog stop and we both were very surprised at how strong the winds were blowing.

That extra sway bar made a huge positive difference.

Hello Mike60, We have the same year/model that we bought used (5100 miles) five months ago and just love it. It has had some quirks and issues that I have mostly resolved. Our most recent adventure revealed the need to further address suspension upgrades. On our way home (south central Tennessee) from the Smokey Mountains going west on I40 with 30 to 40 mile wind gusts from the south was ummm "EXCITING"!! The previous owner had dealer installed steering stabilizer, Kono shocks, upgraded rear antisway bar and front sway bar. I have been eyeing the Sumo Springs and will get Wifey to read this thread to ok the purchase!!

I'm curious about sumos for the front of my Class C. It is my understanding they come in 500 and 1000 pound capacities. What are the thoughts on which one to use? I really struggle to understand how any suspension upgrades are going to help with crosswinds when there is sucha flat side catching the wind.

Interesting. About two and a half weeks ago we drove to Dandridge, east of Knoxville, from Cincinnati and had just about the same winds with gusts supposedly hitting 50.

I, too, had added a Safe-T-Plus steering stabilizer, Koni FSD shocks all the way around, a Roadmaster supplemental sway bar but still use the stock front sway bar, and added a SuperSteer rear trac bar.

We got hit by some scary gusts on the previous trip so I added the Roadmaster 1 5/8" supplemental rear sway bar right before that trip and we actually were surprised by how hard the winds were blowing when we hit a rest area.

We now have about zero push by trucks as well.

Have you ever had a professional front end alignment?
