Product Information


Utilizing the same micro-cellular air springs as the SumoSprings, Trailer SumoSprings mount above the trailer leaf spring assemblies and create a cushion between the axle and trailer frame. These Trailer SumoSprings minimize wear and tear on body-frames, closets, windows, doors, mounted TVs and other components by reducing hop, bounce and sway common in most tow-able RVs. By reducing sway and bounce in the trailer, you can improve driver control, ride comfort and even save on maintenance and overall cost of trailer ownership.

  • Sold as a pair (left and right)
  • Maintenance-free
  • Reduces and absorbs vibration
  • 500 (lb) Capacity at 50% Compression
  • Reduces overall cost of ownership
  • Improves overall driver control and ride comfort
  • Compresses up to 80% of original height with full memory rebound
  • Increases safety
  • Progressive spring rate with superior damping properties
  • Made from patented micro-cellular urethane
  • Will not leak or rupture
  • Never load any vehicle beyond the manufacturer's GVWR

Founded in 1996, SuperSprings International, Inc. has expertly designed, developed, patented and introduced various innovative suspension solutions for commercial and recreational trucks, vans, cars, sport utility vehicles, trailers and more.
