DETACHABLE GOOSENECK (LOWBOY) TRAILERS

Jet Trailer's high quality craftsmanship and attention to detail puts our Hydraulic Detachable Gooseneck lowboy trailers in a class of their own. In addition to using high strength steel, our RGN trailers are comprised of four engineered beams that are automatically welded on both sides. As a result, our detach trailers have a high safety rating.

Jet's Lowboy trailers are manufactured in standard capacities of 35 Ton, 45 Ton and 51 Ton. All models are available in various lengths and axle configurations to accommodate your hauling needs. Furthermore, Jet offers popular options that include easy to use heavy duty three beam aluminum pull outs, outriggers, full width aluminum top deck, lift axles, & flip axles to accommodate your large and oversized equipment.
