Description
Les SumoSprings® sont un produit de suspension breveté conçu pour améliorer la capacité de charge, stabiliser le roulis et améliorer le contrôle général du conducteur ainsi que le confort de conduite. Ils ne nécessitent aucun entretien, ne fuient pas d'air et n'ont pas besoin de conduites d'air ou de compresseurs. Les SumoSprings® sont fabriqués dans une variété de hauteurs, de diamètres et de densités pour supporter de multiples applications avant et arrière. Ils sont fabriqués à partir d'un polyuréthane propriétaire à cellules micro-cellulaires fermées, offrant un taux de ressort doux et progressif avec des propriétés d'amortissement supérieures. Chaque SumoSpring est fabriqué à la main avec soin, rendant chacun unique avec ses propres caractéristiques naturelles, telles que de légères variations de couleur et des bulles de surface – preuve du savoir-faire qui entre dans chaque pièce.

Working with the tech to make sure I got the right sumo springs was really helpful. Install was quick and easy. Immediately I notice improved ride quality and handling. And no more squat with the trailers.
Ron Jardine –
Significant improvement in bounce improvements in brake response as well
Troy Cobbley –
Awesome product as always!
Boyd Henderson –
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.

Significantly reduced rear sag to almost unnoticeable when towing travel trailer. Better ride and control. Guy with same truck and similar trailer stopped me when leaving campground and asked me how I got everything so level. Highly recommend.

Even though we have one of the best hitches, we still had some porpoising when towing our travel trailer. After having the Sumo springs installed, it’s gone, and the ride of the truck feels more like a truck should instead of like the bouncy ride of an old Cadillac. Very glad we purchased these springs instead of going the expensive air bag route.

I have had these on my truck now for two full years. These have been a major improvement for towing heavier loads with my F150. The only downside I have found is they are very affected by cold weather. I live in northern Illinois and once the temperatures get below about 15°F , it’s pretty brutal when you hit any bumps. I take mine off in the winter because most of my towing is done spring through fall. Just something to consider if you live somewhere that gets cold for an extended period of time. Five stars in the summer, two stars in the winter.
