Best 5th Wheel Upgrades

Unlike traditional bump stops or rigid suspension components, Trailer SumoSprings provide progressive resistance — soft when lightly loaded, firm when carrying heavy cargo. This means less bounce, more control, and a safer towing experience whether you’re hauling a lightweight camper or a fully loaded 5th wheel across the country.

Cosa dicono i nostri clienti

I have SumoSprings installed on my fifth wheel and absolutely love them. Not only do they improve the ride, but I believe they also help protect the frame by distributing the load more evenly. It gives me peace of mind knowing the weight is better supported. And if you ever run into a frame issue, they can easily be removed before heading to the dealer. A smart upgrade all around.

Keystone Cougar 5th Wheel

Love these! They’ve reduced sway dramatically, making towing so much more stable. What surprised me most is that the difference is noticeable even when parked — the trailer feels more solid and less wobbly when we’re moving around inside. It’s a small upgrade that makes a big impact on comfort and confidence.

Forest River Cedar Creek 5th Wheel

I’m loving the SumoSprings on my Grand Design 5th wheel. The ride is smoother, the trailer feels more controlled, and the sway is practically gone. For the price, the improvement in handling and stability is worth every penny. It’s one of those upgrades I’d recommend to any 5th wheel owner looking for peace of mind on the road.

Trailer Sumosprings for your 5th Wheel

Due applicazioni. Abbastanza per coprire praticamente ogni trailer là fuori.

I Trailer SumoSprings sono realizzati in poliuretano microcellulare. Progettati per eliminare rollio, sobbalzi e vibrazioni, queste alternative agli airbag a manutenzione zero aumentano il controllo complessivo del conducente e il comfort di guida durante il traino. Se il tuo rimorchio ha assali con una portata di 5.000 libbre o superiore, avrai bisogno dell'opzione nera (-47). Questo ti offrirà il miglior supporto del carico e controllo.

Kit Assali "Spring-Over"

Kit Assali Sospesi a Molla

Piastra di contatto per rimorchio SumoSprings

Se il tuo rimorchio è dotato di un telaio sfalsato rispetto all'asse, è necessaria una piastra di contatto per l'installazione dei tuoi Trailer SumoSprings.
