A trailer jack is a mechanical device used to lift and stabilize a trailer for hitching, unhitching, or level parking. Typically mounted to the trailer’s tongue, the jack allows you to raise or lower the front of the trailer for easy attachment to a towing vehicle. Trailer jacks come in various types, including manual, electric, and hydraulic, depending on the load capacity and ease of use required. With adjustable height and a sturdy base, they ensure stability and balance when the trailer is stationary. Essential for trailers carrying boats, campers, or cargo, trailer jacks provide safety and convenience, making it easier to manage heavy loads during transport or storage.
