Helpful for stability and smooth ride
These were easier to install than the front Sumo Springs and they do seem to improve overall handling and ride. I installed them shortly after getting my camper van because virtually everyone who had tried them said they made a significant improvement. They seem to be working fine three years later.

Much improved handling
Bought these and the front ones as well for our 2022 Dodge ram Promaster 3500 travel van. Easy in install, and the ride difference is huge. Wife thought it wasn't a smart purchase till we test drove it with the new springs. You will not be sorry you bought these.

Good investment
A good investment and handles better.

height after install
These were intalled on an already RV converted Promaster 3500.I removed one of the spacers and after install they sit 1/4 inch above leaf springs. Takes potholes much better and most of all, corners much more level with little to no sway. Hopefully this will also eliminate ,or drastically reduce, wind sway during highway miles.

0 Stars for this Seller!! 5 Star Product
SumoSprings are Outstanding but this amazon store has deceptive shipping dates on this product and had a 1 to 2 day on its Amazon product page but as soon as I paid on Oct 17th and they sent shipping tracking information UPS had it arriving Oct 22nd but on the add it was Oct 18-19th on Amazon. Please don't buy from this Amazon store they USE Deceptive shipping dates.

SuperSprings work well
SuperSprings were easily installed and have performed as expected. They have stiffened up the ride in my Travato 59g and increased the clearance by an inch. Installation was as easy as jacking up the rear of the RV (one side at a time) and unscrewing the original bump stops and screwing the SuperSprings in. I did not remove the wheel as others had suggested.

Huge difference/improvement in ride
A few minutes of your time and a few simple tools is all it takes to install these Sumo Springs and they add so much stability and comfort to your ride. Have them on both my RV and work vehicles.

Wasn't hard to install, better cornering, extra 1" of lift on Class B RV
These improved my 2017 Dodge Ram 2500 based Class B RV Ride (mtn road side-sway) and rear ground clearance (adds about 1"). Although feels more front bounce and back-kick over bumps. In my opinion, they are worth it just for the added clearance for the expensive RV stuff under the chassis, the ride effect depends on the roads one drives and folks personal feel. Using these injunction with the Front Coil stiffeners. Installation these by myself in less than a hour.

Ces SumoSpring ont fait une grosse différence de conduite, la camionette est beaucoup plus stable dans les virages et sur chemin cahoteux. L'installation a été simple et rapide, juste a dévisser l'original et revisser le Sumo.
