What are Sumo's and why should I get them?

I keep seeing people referencing adding "Sumo's". What are they, what do they do, why should I get them and what do they cost with installation?

EDIT - I know my ordered RV has a Hellwig sway bar whatever that is.

In a nutshell, they are helper springs. They help bring the unit more up to level if you have heavy load. In a MH it would help the ride from being "wallowy" I think. Fairly easy to install the the people there are fantastic!

Your mbs has a great ride already but the sumo springs make it even better. They keep the frame and axels in constant contact so that any bump in the road will be absorbed by the springs. I think they made a huge diff. Check out the suspension connection.give them a call great people to deal with. I have also replaced my factory shocks with bielstin shocks factory shocks reave a lot to be desired.

I have the sumos in the rear. Easy install. Some difference but I wouldn't call it huge.

Front & Rear = Huge

I did rear first and followed up with the front. Made all the difference. Very stable, quiet and smooth ride.

Rig is also very stable when parked and don't need the Bigfoots.

When removing mine I sprayed the originals with silicone spray and they popped right out. Made the new ones go in really easy.
