Specs:
This jack will take the work out of lifting and lowering your trailer. The 30-amp motor ensures trouble-free operation and consistent power with the flip of a switch - no need for a crank. It also has helical-cut gears, which have angled teeth that mesh together clearly. This allows for quieter, more efficient operation than a jack that uses a standard Acme screw.
To ensure great performance even at night, this jack also comes with a front-facing light that houses 3 LEDs. The light is directed at a downward angle allowing for easy deployment and retraction of the jack in low-light settings. The unit also comes with a manual crank handle in case you lose power.
This jack can be bolted or welded onto your A-frame coupler, or it can sit in a brace behind the coupler. As with other Lippert jacks, it is constructed of powder coated steel to ensure that it will resist rust and corrosion and hold up well to the elements. The housing on the jack protects the internal components, and it has a durable, UV-resistant coating that resists chips, cracks, and fading.
You always want to be sure when purchasing a tongue jack that the jack capacity at least matches your trailer's tongue weight (TW). Your trailer's TW should be around 10 percent to 15 percent of your gross trailer weight (GTW), which is the weight of your trailer when it's fully loaded. So if you have a 5,000-lb trailer you would want a jack that can support at least 500 lbs to 750 lbs.
A trailer jack is designed to lift the tongue of your trailer so you can connect the trailer coupler to your hitch ball. To do this, you'll need a jack with a lift capacity high enough to handle your trailer's tongue weight.
Tongue weight is the amount of weight that your trailer applies to the back of your tow vehicle. Typically, your tongue weight should be 10-15% of your total trailer weight (trailer + cargo). In other words, a 10,000-lb trailer would have a tongue weight between 1,000 lbs and 1,500 lbs. For a trailer this size, you would need a jack with a lift capacity of at least 1,500 lbs.
It's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher lift capacity should operate more efficiently, allowing you to spend less time cranking and more time camping.
Every jack offers a certain amount of lift or travel. Screw travel is the distance the jack extends when you crank it (or toggle it to "extend" on an electric model). Some jacks include a drop leg for extra adjustability. On these jacks, you'll see the maximum extension of the drop leg listed in the specs as well. Adding the screw travel and drop leg travel together will give you the total lift. The total lift listed above can help you determine how high this jack will be able to raise your trailer.
