Trailer Jockey Wheel

A trailer jockey wheel is a height-adjustable, retractable wheel mounted on the drawbar or A-frame of a trailer, engineered to support the trailer tongue when disconnected from a towing vehicle and improve maneuverability during coupling, storage, or repositioning operations. By lifting or lowering the nose using its integrated screw or swivel bracket, the jockey wheel facilitates precise alignment with the towing hitch and eases the effort required to connect or disconnect the trailer, while its caster action allows smooth movement in any direction—ideal for tight spaces or uneven terrain. These wheels are constructed to carry a specified static nose load—ranging from several hundred kilograms on light models to over 700 kg on heavy-duty units—and feature sleeve diameters typically between 42 mm and 60 mm, ensuring compatibility with different trailer classes.
