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.

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.

Great product, had the same set up on my 2014 Toyota Tundra and have been really pleased with the springs.

I recently purchased the SSR-217-40 for my 2020 Chevy Trailboss. They arrived in 3 days (CA to VA) and I was very impressed with the shipping speed and happy to receive them. I put them on last night and everything went on and fit as expected. I did use the optional 1″ spacer, but have yet to load it down. I expect I will leave the spacer to help with a faster preload. I installed them by myself in about 30 minutes in my driveway and jacked up my truck with a floor jack under my drop down trailer hitch. Lifting the rear end as high as I could without taking the tires off the ground gave me plenty of clearance. The kit came with everything needed, down to a small tube of blue locktite.

Excellent order processing. My order was shipped much sooner than estimated ship time when I placed the order.
Just completed an 800 mile round trip with my new SumoSprings installed on my trailer. The improvement in ride and towing experience is remarkable. This is the best modification to my trailer yet. If I buy another trailer SumoSprings will be the first thing I install.

The blue one added a slight lift without sacrificing the ride

EASY TO NAVIGATE WEBSITE. I CALLED THE CUSTOMER SERVICE NUMBER AND SPOKE WITH A VERY INFORMATIVE PERSON TO VERIFY I CHOSE THE RIGHT SUMO SPRING FOR MY TRUCK.

Great product but you need to make a separate kit for the trailboss which includes the 1” nylon spacer and the 2” nylon spacer with a M10-1.5 bolt in 90mm and 120mm. The standard kit does not fit the trailboss in the way the instruction manual describes, and it would be a very simple fix to produce a kit specifically for the trailboss.

Great product and awesome customer service. They did an awesome job explaining the differences between products and proving great recommendations of what I need and don’t need.
