Descripción
Los Coil SumoSprings® mejoran la capacidad de nivelación de carga de los resortes helicoidales delanteros y traseros originales. Fabricado con uretano microcelular, la tasa de resorte progresiva del material con propiedades de amortiguación superiores crea un efecto de amortiguación, mejorando la capacidad y la comodidad de marcha. Se instalan simplemente deslizándolos entre las espiras del resorte helicoidal. Cada SumoSpring se fabrica a mano con cuidado, lo que hace que cada uno sea único con sus propias características naturales, como ligeras variaciones de color y burbujas en la superficie, prueba de la artesanía que se pone en cada pieza.

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!
