ABSTRACT:
A trailer the spring for boat trailers the spring being readily fabricated from corrosion resistant materials and in particular aluminum, stainless steel and polymeric materials. The trailer spring has a base which is secured to a frame component. An elongated beam is pivotly attached to one end of the base such that the other end of the beam can pivot in relation to the base in a vertical fashion. Positioned between the pivoting end of the beam and the base is a section of an elastomeric material which may be compressed between the pivoting end of the beam and the base. The section of elastomeric material may be retained in a holder. In the preferred embodiment the beam has a U shaped cross section which has upstanding sidewalls which project around the base and the horizontal frame component when the spring is compressed. The projection of the beam around the base and frame component tends to increase the transverse stability of the trailer. Integral with the subject trailer spring is the trailer axle. The trailer spring of this invention is used in pairs.
