SSR-313-54 Pair of Rear SumoSprings fits 2014-2025 Ram ProMaster 1500/2500/3500 2WD | Softens Harsh Rebounds | Reduces End Sag | Stabilizes Sway | Made in USA

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.

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.

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.

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 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.

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.

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.

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.

Très très efficace suggérer vraiment pour les van life

These were easy to install and do exactly as described very happy

Easy to fit and supports rear leaf springs (stops rear sag) under loads

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.

c’est un bon compromis contre des ballons à air
