8 Factors You Need to Consider When Purchasing Trailer Jacks

Trailer type

It is very vital to choose suitable jacks for your trailer. You have to choose the Jack according to the type of trailer.
Different types of jacks are used for different types of trailers. Generally speaking, Boat trailers use Marine or Swivel jacks. They also have a high requirement for corrosion resistance.
For A-frame utility, camper, and landscape trailers, the A-frame jack is usually used. The A-frame jack is often used for agricultural and commercial trailers.
RV trailer & camper trailer are often used trailer scissors jack.
Most of the heavy-duty trailers are selected with a square jack.

Elevated Height

Jack's lift height is one of the most important indicators to determine if the Jack is suitable for your trailer. It would be best to have a clear idea of the original Height when not lifted and the height when raised to its highest point.
With the trailer parked on level ground, measure the trailer connector's height from the ground to the bottom of it. The Jack should be about 4 inches above the connector's horizontal height so you can lift it over the ball to connect and disconnect the trailer.
The Jack should shrink less than the height of the horizontal trailer's hook. It should also retract (or steer elsewhere) without touching the ground when the trailer is towed away.

Installation / Mount

Trailer jacks are mounted to the tongue or frame of a trailer in different ways. The most common are weld-on jacks and bolt-on jacks. Welded jacks are usually stronger, but they are difficult to replace. Bolt-on jacks come in a variety of connection configurations.

Swing Mode

Trailer jacks are raised and lowered by cranking. Some jacks have the crank mounted in the top position, while others have the crank mounted in the left and right wind-up position. Some things on your trailer may prevent you from turning the top crank, but the side crank will not. Choose the right swing mode for your trailer and your preferences.

Load / Capacity

Most jacks are not designed to support the entire trailer. Pick a jack that can hold the weight of your trailer tongue. Typically, the tongue weight is 10-15% of the total weight of the trailer. Simply, a heavy-duty trailer jack is required to support a heavy trailer.


General packaging, one-piece into a plastic bag, and then into a crate.
Customized packaging can also be designed according to customer's requirements.

Driving Forces:

Depending on the power system, the trailer jacks can be divided into manual and electric.

A manual jack is made with a handle to raise and lower the tongue. You have to use your hand to operate the Jack. The number of revolutions you have to turn depends on the level of the grade you are in or the hook's height.

Electric jacks are a gear-driven mechanism. It only requires the strength of one finger to work. You can choose "up" or "down." It runs on 12-volt power only. It is much easier to use than a hand jack.

Surface Treatment

The surface treatment of the trailer jack is generally zinc-plated, powder-coated, hot-dip galvanized and so on.

Electroplating is the process of applying zinc using an electric current. It has a thinner coating than hot-dip galvanizing and is relatively less resistant to corrosion. It has the advantage of brightness and uniform colour, making it more aesthetically pleasing.

Hot-dip galvanizing is the process of dipping a product into a molten zinc solution and applying a protective zinc coating. Hot-dip galvanizing is an ideal method of applying a protective coating due to its low cost, ease of use and long maintenance-free life. Typically applied from 830 to 870 degrees, the zinc will bond to the steel. It is the most common finish for outdoor corrosion protection.

Powder-coated involves the electrostatic application of a dry powder to a metal workpiece's surface, which then cures the product to form a protective layer. The benefits of spray moulding include creating a thicker coating than paint or other liquid coatings. Spray moulding is environmentally friendly because the coatings do not contain solvents and do not release volatile organic compounds (VOCs) into the atmosphere.
