Sumo Springs

[AZ Wonderer]

Does anyone know if Sumo Springs are compatible with the LEII?  If so, has anyone installed them and with what result?

Well not on a trailer but on my trucks. Pulling a 5000 to 6000lbs boat without a  Andserson or Easylift hitch with a 1/2 ton is not fun. With boats Sumo springs it is a whole lot better. I have installed them on two of my own trucks and two company trucks that tow boats.

Why do you think you need them?

I installed Sumo Springs on a half ton Chevrolet pickup and pulled an Elite 2 to Maine and back. I was a lot happier when got home and traded that truck in on an HD2500 Duramax. Sumo Springs are a polyurethane bumper. Not the same as steel leaf springs. 

edit:

@AZ WondererI had had a beer or 6 when I read your first post. I have reread your post and now see that you were asking about Sumos under the trailer, not the TV. After watching the video I want to investigate these further since there are no bumpers on the current setup.

I had some on my previous 36 foot fidth wheel  Grand Design and it didn’t worked well because they work only on compression and not on decompression mode. The first 50% of the Sumo, when starting compressing there is no compression resistance and after that its getting too hard. After a few months, i get rid of them and went in Elkard Indiana to get a MoRyde indépendant suspension installed and that’s made a great difference. Sorry about my written english, i’m french Canadians! You don’t need that on an Oli because you already have shocks that work on both mode.

@AZ Wonderer Thanks for your original post. I was interested in this enough that I rolled under my E2 this morning to take a look. 
 

My ubolts have hit the frame. There’s less than 2 inches of travel there

 

There is a crossmember in front of the front axle and behind the rear axle so that rules out installation in those positions 

The product requires a 7.4 - 8.65 inch gap for installation 

 

Font axle gap, level, empty, on concrete floor

 

Rear axle gap, level, empty, on concrete floor 

 

I like the idea of a bumper of some kind in that location but it doesn’t look like the Sumo Springs will work. Thanks again @AZ Wonderer for posting that link.

Thank you for doing all of this!  It's great information.  Now I know the Sumo Springs won't work on an LEII.  I originally learned about them from an RV YouTube couple, Wayward Wags, who installed them on their 5th wheel.  The couple set up a camera inside the RV both before and after installation to show the difference in the amount of movement and jarring inside while traveling.  The Sumo Springs seemed to make a big difference.  But, unfortunately, based on your research above, they won't work on the LEII.  Thanks again.

@AZ Wondererwe need to get them to make a shorter base so that these would work on an LE2. I would be willing to try a set. I really don’t like that there isn’t a rubber bumper to keep the ubolts from hitting the frame. I think I could fab a set of bases using my mill and welder.  I sent them a email asking how many springs come in a set. I bet it’s only 2.
