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.

What Our Customers Are Saying

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.

Laurie Lautrup

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.

Brian Heugly

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

Two applications. Enough to cover just about every trailer out there.

Trailer SumoSprings are manufactured from our micro-cellular polyurethane. Designed to remove sway, hop, & vibration, this zero-maintenance airbag alternative increases overall driver control and ride comfort when towing. If your towable has axles with a weight rating of 5,000lb or greater, you’ll need the black (-47) option. This will you give you the best load support and control.
