Descrizione
SumoSprings® sono un prodotto brevettato per sospensioni progettato per migliorare la capacità di carico, stabilizzare il rollio e migliorare il controllo generale del conducente e il comfort di marcia. Non richiedono manutenzione, non perdono aria e non necessitano di tubazioni dell'aria o compressori. SumoSprings® sono prodotti in una varietà di altezze, diametri e densità per supportare molteplici applicazioni anteriori e posteriori. Sono realizzati in uretano proprietario a cellule micro chiuse, che fornisce una curva elastica fluida e progressiva con proprietà di smorzamento superiori. Ogni SumoSpring è realizzato a mano con cura, rendendo ognuno unico con le proprie caratteristiche naturali, come lievi variazioni di colore e bollicine superficiali, prova dell'artigianalità che caratterizza ogni pezzo.

Installed both the yellow on the rear and the blue on the front of our 08 Bounder and the change was like night and day. We are so grateful for your products and will recommend them to everyone we meet and know. The coach rides and handles like a different motor home. Wow. The ride, sway, ease of handling are all greatly improved. Thank you Sumosprings. Outstanding.

I can’t remember the last time I was so thrilled with a purchase. The front and rear Sumo Springs are incredible on our 2017 Newmar Bay Star 3401.
I recently test drove a 2022 Newmar Bay Star 3609. The ride that I now have, far surpasses that new chassis.
Here’s my impression.
The RV feels composed, stable and unified. It is remarkably much more quiet on the road. Steering is truer. Sway is under control. What I like the most is that the RV feels like a solid unit when encountering bumps, uneven road surfaces and turns.
The installation was straightforward. All of the hardware was top notch.
I am a “happy camper”. Thank you for designing a quality product that actually works! I have already made two recommendations and will be telling other RV’ers about your product and my experience. Thank you for the support. Keep up the good work.

The kit went on was easy to line up and bolt in, the only drawback there were bolts and nuts missing from the kit, had to go buy grade 8 bolts and nuts, would recommend highly.

Front made amazing difference. Back some but not as much. Worth every penny. Trying to get a buddy to buy them for his Baystar. Told him to save the money on liquid springs and get the sumo springs.

The front were easy to do on the ground. The rear needed a big air wrench and bottle jacks. Both were easy to install and what a difference it makes in ride and handling.
