How to Determine the Lift Capacity You Need in a Jack

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.


Trailer and Camper Jack Lift

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.

  • Installing the Ultra-Fab Electric A-Frame Trailer Jack # 38-944017
    The Ultra-Fab Electric A-Frame Jack - 18" Lift - 3,500 lbs # UF38-944017 can be wired for both the power and a ground to go to the battery, you would just need to add the jumper wire for the ground connection as it is designed to be grounded to the trailer through the mounting flange. The # UF38-944037 has a 7-way plug to power the unit so no other power is needed if you prefer.

  • Economically Priced Powered A-Frame Jack that Wires Directly to Trailer Battery
    In your price range the best option is the Ultra Fab powered A-frame jack part # UF38-944017. This jack can be wired directly to your trailer battery for operation and will work well. It has a 3,500 lb lifting capacity. I attached a review video for this jack for you to check out as well.

  • What Cost Effective Option do You Have to Raise the Front of My RV to Level it?
    Hello again Roger, I'm sorry, but I cannot recommend using trailer tongue jacks like the Ultra-Fab Electric A-Frame Jack # UF38-944037 for leveling your RV. A trailer jack is specifically designed for lifting the front of a towable trailer, not the full weight of a self-contained vehicle like a motorhome. These jacks are mounted to a trailer’s tongue and are rated only for tongue weight, which is a small portion of what a motorhome's front axle carries. Since motorhomes lack a tongue structure,...

  • Electric A-Frame Trailer Jack With Outer Tube Diameter of 2 Inches
    There is an option for an electric A-frame trailer jack that with an outer tube diameter of 2 inches, though the jack you mentioned has an outer tube diameter of 2-1/4 inches. For an electric A-frame trailer jack that has an outer tube of 2 inches and an inner tube of 1-3/4 inches you would need to go with a jack from Ultra-Fab: - Ultra-Fab Electric A-Frame Jack # UF38-944017 - Ultra-Fab Electric A-Frame Jack with 7-Way Plug # UF38-944037 Both of these are 3,500 lb jacks that will work...

  • Can I Wire and Electric Trailer Jack Directly to the Truck Battery
    You could technically wire an electric trailer jack directly to your truck's battery, but that isn't really the most practical setup. I've seen one guy pull out his jumper cables every time he wanted to use the jack in this fashion, but I can't say the safety factor didn't worry me. Another thing to consider is that the wire gauge used on electric trailer jacks isn't the most ideal for running up to the front of a truck due to the wire length required and the amp draw of the jack motor....

  • How Do Powered Trailer Jacks Draw Power, From Battery or 7-Way
    The Ultra-Fab Electric A-Frame Jack # UF38-944037 that you referenced would simply plug into the 7-way at the rear of your tow vehicle and would draw the power needed for the jack to work from the vehicle battery. Most all other tongue jacks are hard wired to the trailer battery directly. A good example is the Lippert # LC285318 tongue jack rated for 3500 pounds.

  • Trailer Jack for 2019 Forest River Micro Lite
    The electric jack I strongly recommend for your 2019 Forest River Micro Lite 21FBRS is the Phoenix Electric Trailer Jack # UF38-944040 because of its unparalleled performance in regards to speed. This jack will give you 10" of travel in just 18 seconds, making it the sports car equivalent of electric trailer jacks; it has 22-1/2" of total travel and a 4,000 lb lift capacity, which is more than enough for your Forest River. This jack does get wired to a 12 volt power source, as you can see...

  • What Size Battery Should be Used to Power Bulldog Electric A-Frame Trailer Jacks
    A standard car battery will work to power Bulldog trailer jack # BD500199. The battery will need to have an amp hour rating greater than 30 amps which is the max current draw of most electric A-frame jacks. Other option is to use jack # 3370093500 or # UF38-944037 provided your tow vehicle has a 7-Way trailer connector with functioning 12 volt circuit. Both of these jacks are powered through the 7-Way so no battery is required on the trailer to run the jack. I have linked videos for all...

  • Troubleshooting An Ultra-Fab Electric Trailer Jack That Just Keeps Blinking
    Typically if an Ultra-Fab electric trailer jack is just blinking it indicates that the power source isn't enough to fully operate. Have you checked the voltage running to the to jack with a multimeter # PT89ZR to ensure it's getting a full 12 volts? A fuse is going to blow to protect the jack's circuit board but doesn't always come included. You could use an inline fuse holder # SWC9538 to properly protect your jack. You will need to look at the amperage pull to determine the correct...

  • Circuit Breaker Location On Ultra-Fab Electric A-Frame Trailer Jack 3502-7
    The circuit breaker on the Ultra-Fab Electric A-Frame Jack w/ 7-Way Plug # UF38-944037 is located on the side of the jack(see image). As we do not carry this particular breaker 38-101283 anymore you can replace it with a 20-Amp Pollak Circuit Breaker # PK54520

  • Troubleshooting Blinking Light and Nothing Working on TL4500 Electric Camper Jack
    We do not currently carry the TL4500 model jack you mentioned but if the ground is good and your battery is fully charged then there is likely a short somewhere on the wiring that is causing the issue you're having. I recommend simply inspecting the jack's wiring for any damaged, pinched, or exposed sections that need to be replaced. You can also remove the housing to inspect the switch wiring or to see if any water might have found its way inside that could be causing the short. If everything...

  • Troubleshooting Ultra Fab Powered Jack that Stopped Working After Winter Storage
    The Ultra-Fab Electric A-Frame Jack # UF38-944037 that you have gets power by plugging into a trailer connector 7-way on a vehicle. Typically what you described is corrosion on the connector from driving through the winter. Try cleaning of all of the pins on the 7-ways of both the vehicle and the jack and try again. If still nothing you will want to verify that the 7-way on your vehicle does have power on the 12 volt circuit. This is the 1:00 pin of the 7-way on your vehicle.

  • Replacement Jack for 2014 Legend Enclosed Trailer with A-Frame
    It sounds like you likely have an A-Frame trailer, so you can use something like the etrailer Round, A-Frame Jack - Sidewind - 15" Lift - 5,000 lbs # TJA-5000S-B which will attach to the 3 mounting points on the trailer tongue and provide you with a jack with 15" of lift. This jack doesn't come with a foot so you'll also need the Footplate for 2,000-lb and 5,000-lb Round, A-Frame Jacks # JF-99, which is designed for that jack. If you're looking for an electric jack then something like...

  • Troubleshooting Ultra-Fab 4500 Electric Tongue Jack That Blinks and Does Not Operate
    The most probable cause for the lights on your Ultra-Fab electric tongue jack to blink, and for the jack not to operate, is a weak battery and/or grounding problem. This jack grounds through its round mounting flange which contacts the trailer frame. These two mating surfaces must be clean bare metal, free of paint, rust, grease and dirt. Often the fix is simply to unbolt the jack and sand the bottom of the flange and the top of the mounting point on the trailer to expose bare metal. An...

  • Recommended Electric Tongue Jack 2017 Keystone Passport Ultra Lite Grand Touring Travel Trailer
    Hello Scott, so we have quite a few electric jacks that will be of sufficient capacity for your 2017 Keystone Passport Ultra Lite Grand Touring Travel Trailer. If you are looking for the fastest-moving jack, I recommend the Phoenix Electric Trailer Jack # UF38-944040. This has a 4,000 lb capacity and it will move 6" in about 10 seconds under 1,000 lbs of tongue weight. I imagine that with your camper being 7,500 lbs loaded, your tongue weight should be pretty close to 1,000 lbs so you should...

  • Is a 3,500 lb Powered Jack Strong Enough for a Trailer with 7k Axle Capacity
    For your trailer a 3,500 lb powered jack like the part # UF38-944037 would be more than adequate. The lifting strength for a jack is rated for the tongue weight of the trailer. If your trailer weighed 7,000 lbs you would have tongue weight of around 700 lbs so this would work well. This jack powers by plugging into a 7-way trailer connector. If you wanted one that hardwires to a trailer you would want the part # UF38-944017 instead.

  • What Size Battery Should be Used to Power an Ultra-Fab Electric A-Frame Trailer Jack
    The 3500 pound Ultra-Fab A-frame jacks such as # UF38-944037 have a 25 amp circuit breaker to handle the draw of the motor so the battery will need to be rated at least that high which usually isn't a problem for 12 volt car batteries. The slow blow fuse is actually a 30 amp. A breakaway battery will not be sufficient since the amp hour rating is too low. You really need an actual car battery.

  • Recommended A-Frame Power Jack for a Wells Cargo Enclosed Trailer
    I really like the Trailer Valet JXC Trailer Jack rated for 5,000 lbs # TV94FR. This is a newer type of jack that is actually operated by a power drill and I've seen it in action and it moves a lot faster than pretty much any other jack on the market, plus it comes in at a fraction of the cost. The power drill isn't included but since Wells Cargo trailers are typically used for job sites I would imagine you're already carrying one anyways. When you don't have access to the drill or perhaps...

  • What Does Ultra-Fab Electric A-Frame Jack Use as Manual Crank
    While we don't carry a replacement manual crank for the Ultra Fab Trailer jack part # UF38-944037 all you need is a 9/16 inch deep well socket as that's what the included tool is.

  • Can Electric A-Frame Jack Install In Place of Fulton F2 Trailer Jack
    The great thing about A-frame trailer jacks is that they all use the same mounting flange bolt pattern so you can remove your Fulton F2 and install an electric jack in it's place like the part # UF38-944037 and you'd be set.

  • Are Fuses Needed on the Wiring for the Bulldog Powered Drive Trailer Jack BD500200
    The Bulldog Powered Drive a-frame trailer jack # BD500200 is circuit protected internally so additional fuses or breakers are not required. The jack should be ran off of a trailer mounted battery and not off of the 12 volt circuit through the trailer connector. Tow package wiring is not heavy enough for the full amperage draw of the jack and it could result in melted tow package wiring and/or a drained vehicle battery. For a jack that was designed to plug into a 7-Way trailer connector...

  • Replacement Toggle Switch for Ultra-Fab Jack that Lifts But Won't Lower
    The Ultra-Fab Electric A-Frame Jack w/ 7-Way Plug - 18" Lift - 3,500 lbs # UF38-944037 most likely has a wiring issue since it will lift but not lower. The motor will be polarity sensitive, so it is likely the switch has failed. I recommend removing the switch and replacing it with the Replacement Toggle Motor Switch for Ultra Fab Powered Jacks # UF38-75-1037.

  • Powered A-Frame Trailer Jack Recommendation for a 6,500 lb Trailer
    Typically a trailer's tongue weight will be between 10 and 15 percent of the total weight of the trailer. Since your total trailer weight is 6,500 lbs your tongue weight would be between 650 and 975 lbs. The Ultra-Fab Electric A-Frame Jack # UF38-944037 has a 3,500 lb capacity so it would work well on your trailer and would have more than enough capacity.
