Trailer Life Magazine’s SumoSprings Rebel Review

T.J. Product Review 4 Comments

The good folks at Trailer Life Magazine inquired about our SumoSprings Rebel. They had a pair of RAM 4×4 duallies towing large fifth-wheels. SumoSprings were installed to help level the trucks, stabilize and smooth the ride. Read the article at TrailerLife.com!

“With the SumoSprings in place, the front-high attitude was mitigated enough to almost level the truck; load capacity was not an issue, so the SumoSprings had no impact on the weight rating of the axle. Handling with the fifth-wheel attached improved by at least 50 percent, with a noticeable curtailment of wallowing on some roads.”

“SumoSprings in place, the bumpiness was squelched enough to take the edge off the harshness of the ride, making it more comfortable for the passengers. Chucking was not a major issue for either truck, except on certain roads where the SumoSprings reduced the intensity of the pushing and pulling movement.”

  2. We have a 2019 Dodge Ram Big Horn crew cab 4×2 with a short box, 5.7L V8, axle ratio 3.92 and has a max tow package. GVWR is 7100. We’re going to be pulling a 36’ travel trailer that weighs 8380. We noticed a 3” drop on the back bumper when we hooked up to the trailer. We read about Sumo springs in Trailer Life. Do you have a product you would recommend for the truck? TIA.

    1. Hello Michael,

      Thank you for contacting us. Is your Dodge Ram a 3500? I will need to confirm the model of the vehicle before I can provide you your options.
