Description
Les SumoSprings® pour ressorts hélicoïdaux améliorent la capacité de mise à niveau de la charge des ressorts hélicoïdaux d'origine à l'avant et à l'arrière. Fabriqué en uréthane micro-cellulaire, le taux de ressort progressif du matériau, avec des propriétés d'amortissement supérieures, crée un effet de coussin, améliorant la capacité et le confort de conduite. Ils s'installent simplement en les glissant entre les spires du ressort hélicoïdal. Chaque SumoSpring est fabriqué à la main avec soin, ce qui rend chacun unique avec ses propres caractéristiques naturelles, telles que de légères variations de couleur et des bulles en surface, preuve du savoir-faire artisanal qui entre dans chaque pièce.

Thank you guys for these unique products. I couldn’t imagine being able to fit a 33.3″ without any lift/level on my F-150. However, these Coil SumoSprings are far much better than any level in the market. The ride became different, with more stability at the front. They have eliminated the vibration on gravel terrain without deflating the tires.

Great customer service whether it was answering my questions quickly via email or delivering my order to Australia in super quick time. Even when I had a problem with my order (my mistake) it was rectified pronto.

Significant improvement in bounce improvements in brake response as well

Took the endless bounce out of the suspension when pulling the boat. Truck will corner with much more confidence and less roll in the front end.

Shipping was quick. I have not had the opportunity to install them yet. I previously had purchased the rear SumoSprings for a 2010 Nissan Frontier. They made a huge difference in towing our trailer. I also purchased the SumoSprings for a tandem axle (axle over spring) trailer. While I don’t feel it as much, I am sure they help as otherwise, there would be nothing other than the factory equalizer to help absorb the road bump stress.
I have recommended SumoSprings to several people. I would not have done so if I did not feel that they were beneficial. I considered air bags, but wanted something without the complication of pumps and lines. These work well. Thank you for making a great product.

Very helpful when I had questions and I was impressed with knowledge and expertise of your staff. Shipping was on time. I have yet to install the sumo springs and plan to do some right after the new year

MY 30 YEAR OLD VANS RIDE WENT FROM BUMPY TO LIKE A NEW VAN. LOVE MY SPRINGS.

This was easy to install and works great. We didn’t need to do the front because we only load the bed of the truck and never tow, but bought them anyways.
This product is so worth it. It made a big different. We are very happy!
