What Our Customers Are Saying

Just fantastic. I had the SumoSprings installed on our 4,100 lb single-axle travel trailer and I’m amazed at the improvement. There’s almost no sway, and the trailer feels planted on the road. Rough roads and railroad tracks used to jolt the tow vehicle, but now I often don’t feel or hear the trailer at all. I was worried about a stiffer ride causing more bounce inside, but the opposite is true — cushions, drawers, and cabinets stay in place. This has been a huge upgrade in comfort and confidence.

David

Gulf Stream Vista Cruiser 19ERD

 I added sumo springs about 6 months ago and we have traveled about 5K miles since. Can honestly say that they are one of the best upgrades we have done. Much smoother towing and things do not move around as much inside. I did read multiple reviews and stories before installing them and I think the key is to make sure you are not preloading them too much. I measured per the directions, installed them, dropped the trailer on them and then, looking at the amount of “squish” in them, decided to remove one of the spacers. I had previously installed on a F-150 I had and had too much preloading on them and it behaved a lot like you are describing. You really want the frame to only squish them down about 1/4″. That way the Sumos have some “soft” left in them to absorb the little bumps before they start firming up more to catch the bigger ones.

Keystone Passport

These were very easy to install and immediately improved the ride of our camper. The trailer now tows much smoother, feels calmer in crosswinds, and big rigs passing no longer push us around. Even inside, things stay in place with less shifting or rattling during travel. The ride is noticeably better, and overall it’s made trips far more enjoyable and less stressful.
