Trailer SumoSprings are a maintenance-free suspension enhancement built to create a better journey by reducing G-force in your towable by 68%.  Handmade from micro-cellular polyurethane, they are designed to remove sway, hop, & body roll while increasing overall driver control and comfort while towing.

The TSS-107-47 is designed for trailer frames with a GAWR of 5,000-8,000 lbs with the spring sitting on top of the axle tube. The Black SumoSprings shouldn’t be compressed past 65% of their original height in order to keep full memory rebound.

NOTE:
This product is designed to work on most trailers with the springs mounted above the axle.  The factory spring plate must not be wider than 4-1/4″.  Because of the varying build designs from different trailer manufacturers, there are occasionally some models that this product will not fit.

We watched the SuperSprings video "Trailer SumoSprings reduce G-force vibration | Navistar Proving Grounds". From that video we knew we had to have a set of SumoSprings on our 5th wheel. We recently installed a set of TSS-107-47 SumoSprings on our 2022 Keystone Montana. This installation was very easy taking less than two hours for both axles. The SumoSpring kit had all we needed for each axle - springs, mounting brackets, and hardware. The results? Amazing! Our first 1,000 miles had rough roads. No longer are goods thrown around the 5th wheel. As an added benefit, the truck ride is improved. The up and down shock from the 5th wheel is substantially reduced and doesn't transfer into the cab. Excellent engineering and knowing the SumoSprings will help protect our RV investment.
