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.

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.

Better improvement
These are great comparisons to the original springs on a promaster! Best up grade part for suspension. Be aware for promasters my original springs had to cut off because of the inside bolts ect being exposed to weather over time ect. Otherwise easy installation.

It's worth to have for a RV going off road
We have a mechanic installed for $100 before our trip to the Olympic National Forest. It's quite a different feel going out on rough NF (National Forest) and FS (Fire/Forest Service) roads. It's worth the money.

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.

Handles much better since installing these on my class B RV
Very easy to install. Since adding them, you can definitely feel the difference while driving around bends and on the highway. Would definitely recommend.

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.
