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

Bought April 23 fitted to a Fiat Ducato replacing factory bump stops as you’d expect. I believe these are the ones recommended for a Ducato / Ram pro master. Vehicle weighs 3100kgs on the road and 3.5 max.Initially I was impressed the ride was improved and I really felt good about my purchase after all spending 300 GBP for bump stops they really ought to be good. Unfortunately lately (Jan '24, so 8 months) the ride was unbearably harsh so I checked them out and removed them. You’ll see from the photos they appear to have failed, deformed and are now completely useless.Perhaps these ones were faulty, perhaps I purchased ones that were too lightweight, in which case it’s my own fault but from my research and recommendations from reviews, YouTube etc I see many other folks fitting these exact ones, to the exact Van I own so I don’t think I’m alone on this.All I can really conclude with is, before parting with a considerable chunk of cash if your situation is similar to mine then I strongly suggest you re consider. I have now installed air bags on the rear, oddly purchase cost is very similar, in fact I see the asking is now 400+. The airbags were 350, think of airbags as variable capacity, high strength, bump stops and before you click buy on the above, know that I wish I hadn’t and should have skipped this learning experience, so perhaps you could too. If you do buy, or have bought, please, please inspect regularly.

I installed these on the rear of my Solis 59P camper van. Being so tall, the van has quite a bit of sway which I noticed going around curves. The hardest part for me was accessing the area. I needed a hydraulic floor jack to lift each side, first lifting the driver’s side. I used a screwdriver and hammer to remove the old bump stop and installed the super Sumo. Then on to the other side. There are numerous videos on YouTube showing the procedure. I have noticed a difference since installing these. The sway is reduced somewhat and driving on the highway, the ride seems smooth to me like it is just gliding along. I purchased the front Sumos for the front coils which I haven’t installed yet, which are supposed to improve the ride and reduce the sway even more.

These things are amazing. I have a ram promaster 3500 camper van. They are the single greatest thing I’ve done to my van. It rides way better, drives way better, and corners WAY better. I would install them again for sure.

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.

We have a RV built 3500 which was a nightmare on long corners, like merging onto a highway.After installing the Sumos we did a 6000km trip and pretty much EVERY time we went round a corner I grinned at Mrs and mentioned how much they have improved our lives.Install was incredibly easy, I did one side and Mrs did the other in a matter of minutes

These springs changed the feel of the vehicle immediately. The suspension still has plenty of give but less of a bouncy springy action. I've added a lot of weight with water tanks etc so it's good to have this piece of mind with the extra support. I would highly recommend these to other people doing van life projects. I had mine installed by a mechanic as the original 'bump stops' didn't unscrew so easily on my 2016 Promaster.
