Trailer Jack Types, Load Capacity and How to Choose the Right Jack
Trailer jacks are essential components for supporting a trailer tongue, adjusting its height, and helping keep a trailer level when it is disconnected from a towing vehicle. Selecting the right trailer jack requires careful consideration of load capacity, lifting stroke, retracted and extended height, mounting style, and operating conditions.
Common types include A-frame trailer jacks, square tube trailer jacks, pipe-mount trailer jacks, swivel trailer jacks, and drop-leg trailer jacks. Each design offers different mounting configurations and practical advantages for specific trailer applications. Before choosing a product, buyers should confirm the trailer structure, mounting dimensions, and actual vertical load supported by the jack.

Our product range covers different mounting styles and load capacities for a variety of trailer applications. Depending on project requirements, buyers can discuss specifications such as lifting stroke, tube configuration, mounting dimensions, surface finish, and product color.
When purchasing trailer jacks, it is important to distinguish the trailer's gross vehicle weight rating (GVWR) from its actual tongue weight. The correct jack capacity should be selected according to the supported load, manufacturer recommendations, and intended operating conditions. Buyers should also verify the required lifting range and ground clearance before placing an order.
