5′ x 8′ – 3500# Torsion Axle Trailer Technical Information:

  • True trailer bed size is 5 ft. 2″ wide by 8 ft. 3″ long — for a full usable 5′ x 8′ deck size, even with added sides.  We think the width of the cargo is a better measure than the actual width of the trailer.

  • Trailer bed height depends on design options including the torsion arm start angle.  It can range from 16 inches up.  (Bed height in these images is 20″.)

  • Max capacity (depending on options) is 5′ x 8′ – 3500# * including the trailer weight.
  • True Torsion Axle Utility Trailer Design — Engineered for long life — even when fully loading the torsion axle.
