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.

  • How to Determine Weight Capacity of Electric Trailer Tongue Jack for Camper
    You'll need to chose a jack whose capacity is greater than the fully loaded and ready to tow tongue weight of the camper. Going with a powered jack whose capacity is much greater than the tongue weight of the camper is recommended because the jack won't need to work so hard and will therefore last longer. Also, if you're using a weight distribution system on the camper, sometimes you'll want to use the trailer jack to also pick up the rear of the vehicle to put slack into the system so...

  • 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.

  • Does the 20 Amp Circuit Breaker for Ultra-Fab Powered Trailer Jacks Reset Itself
    Once an overload condition has ceased then the circuit breaker should reset itself. It is mounted on the outside of jack # UF38-944017 but should not need any persuasion to reset. If the jack is not powering on it could be that an overload or short still exists or something else in the electrical system from the power source to the jack is not working properly. You will also need to check the in line fuse. If it is blown the jack will not operate. If all the wiring is done correctly and...

  • Does Ultra-Fab Powered A-Frame Trailer Jack have a Manual Crank
    There isn't a hand crank for Ultra-Fab trailer jack # UF38-944017 but instead it uses a 9/16 inch deep well socket that you could use with a ratchet to manually crank the jack should you need to. I have included a link to a video review of this jack for you.

  • How to Grease the Ultra-Fab Electric A-Frame Jack # UF38-944017
    Base on the installation instructions, to grease the jackscrew on the Ultra-Fab Electric A-Frame Jack, # UF38-944017, extend the jack until the grease fitting is aligned with the hole in the outer tube. You can apply enough grease with two pumps from a standard grease gun. To grease the gears, you will need to first remove the fuse from the fuse holder. Next, remove the gear cover via 4 phillips screws to expose the gears. Then, grease the gears using chassis lube and reinstall the cover....

  • 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.

  • Connecting a Power Lead From an Electric A-Frame Jack to Trailer Accessory Battery
    If you are using an internally grounded electric jack like the Ultra-Fab Electric A-Frame Jack, part # UF38-944017, you simply run the power lead to the accessory battery on the trailer and connect it to the positive terminal using something like a ring terminal, like part # DW05705-1. You will also want to make sure the negative post of the battery is grounded to the trailer frame so the circuit is complete. This type of jack will only require the power lead wire to be connected as it...

  • Is Ultra-Fab 3502 Electric A-Frame Trailer Jack the Same as # UF38-944017
    Nothing, the Ultra-Fab trailer jack # UF38-944017 is the same as the Ultra-Fab 3502. They just call it the 3502. Otherwise it is the exact same jack, same components, capacity, lift, color, size, everything. The 38 is just part of the part number.

  • How to Wire 12V Electric Jack to Two 6V Batteries
    If you have a 12V power jack that you want to power with two 6-volt batteries you will need to wire the two batteries in series in order to increase their combined output voltage to 12V. Connect one battery's positive post to the negative post of the other; then use the other remaining posts for connection to your jack. You will want to make sure that your two batteries have the current capacity required by your jack.

  • Recommended Replacment for a FIC 3500 Electric Jack
    To replace your FIC 3500 electric jack, I recommend the Ultra-Fab Electric A-Frame Jack item # UF38-944017. This jack extends 6" in 25.3 seconds with 1,000 lbs of tongue weight. It has an easy bolt-on or weld-on installation for A-frame trailers, with the distance between the mounting holes center to center being 3". The zerk fitting on the lower stem assembly allows access to grease the threaded rod which leads to a longer jack life and overall better performance. The dual side lights...

  • Troubleshooting LED Light On Ultra-Fab Electric A-Frame Jack UF38-944017 Not Turning Off
    The LED Lights on your Ultra-Fab Electric A-Frame Jack # UF38-944017 are controlled via a switch on the back of the head which you can see at the 1:40 minute mark of the included video, and will stay on as long as that switch as on. I recommend double checking that you have the switch on the off position, and if you do you will need to remove the toggle switch on the back to check for any loose wires or corrosion causing it to not turn off. I included a video of the # UF38-944017 for...

  • Replacement Electric A-Frame Jack with Protection from Over-Extension
    We do offer better jacks that have built-in protection from over-extension. I think the best value for an A-frame tongue jack is the Stromberg Carlson # SC63VR which is rated for 4500 pounds of tongue weight. This is 1000 pounds more than other models, and even though you may not need this much capacity, you will find that the jack motor runs quick and effortlessly. This will add years to its life. This jack also has a unique clutch that prevents damage from overextending or retracting...

  • Recommended Heavier Duty Upgrade For FIC 3500 Electric A-Frame Trailer Jack
    Electric A-frame trailer jacks often have the same bolt pattern, yes. Just keep in mind that a higher-capacity jack doesn't necessarily mean more speed, it's all about the jack itself. For example, the 3,500 lb Ultra-Fab Electric A-Frame Jack # UF38-944017 extends 6" in 25.3 seconds (with 1,000 lbs of tongue weight), while the 4,000 lb Bulldog Trailer Jack # BD500200 extends 6" in 28.5 seconds (with 1,000 lbs of tongue weight). That said, since you mentioned wanting a heavier-duty jack,...

  • Retracted Height of Stromberg Carlson Electric A-Frame Trailer Jack JET-3555
    Based on a review of our manufacturer specs the shortest retracted length among the electric a-frame jacks we offer comes from the 3500-lb-rated Stromberg Carlson Electric Trailer Jack # JET-3555. Since it can happen that a manufacturer may alter product dimensions slightly between production runs, I went to our warehouse and measured one of these jacks myself so that I could be absolutely certain of the retracted length dimension of the # JET-3555. When the inner tube is fully retracted...

  • Trailer Jack Recommendation that Doesnt Break When Over Retracted or Extended
    The circuit breaker of the Ultra-Fab Electric A-Frame Jack # UF38-944017 is designed to prevent the motor from drawing too much amperage and damaging itself. If you were to lower the jack all the way and then keep holding the button you eventually would trip the breaker, but more importantly you would potentially damage the threads of the internal screw of the jack which would permanently break it. I would not advise you rely on the breaker to or the threads bottoming out to let you know...

  • Is A 3,500 lb Jack UF38-944017 Enough Capacity For A 5,000 lb Cargo Trailer
    Hello Wayne. A 3,500 lb jack is going to be more than enough for your 5,000 lb trailer. The 3,500 lb rating is for the tongue weight of the trailer and not the total weight of the trailer. Your tongue weight should be more like 500-700 lbs max so you will be well within capacity for a 3,500 lb jack like the Ultra-Fab Electric A-Frame Jack # UF38-944017, which is a great choice for an A-frame jack.

  • Ultra Fab Powered A-Frame Jack Recommendation that Gets Powered by Trailer Battery
    The Ultra-Fab Electric A-Frame Jack # UF38-944037 is set up to be plugged into a vehicle 7-way whenever it is needed to power the jack. For basically the same jack that would be set up for wiring to a trailer battery you would want the part # UF38-944017 instead. This jack grounds through the mounting hardware and gets powered by the one black wire of the jack that would get run to your battery. Check out the install video I attached for more info.

  • 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...

Ultra-Fab # UF38-944037 rated for 3,500 pounds. This jack also includes a 7-way trailer connector Ultra-Fab # UF38-944016 rated for 4,000 pounds. Each jack offers 18 inches of lift. I've also attached videos of each one for you.

  • Recommended Electric A-Frame Jack With Extended Footplate For Camper
    The Replacement Extendable Jack Foot, part # UF38-751101 will not fit the # UF38-944017 jack you have on your camper because the tubing is not the correct size. My contact at Ultra-Fab said they do not have an extendable foot for your jack. I do have a solution for you. I recommend changing out the jack for the # UF38-944016. This jack has a 4,000-lb capacity and comes with an extendable foot that adds an additional 5-1/2 inches of height.

  • Powered A-Frame Jack Recommendation for 2006 21foot Ameri Lite by Gulfstream
    Powered A-frame jacks have weight ratings that are based on the amount of tongue weight they can lift and are often way overrated for the trailers they are installed on. For example the Ultra Fab powered jack part # UF38-944017 that you referenced has a lifting capacity of 3,500 lb which would easily be enough for your trailer that weighs 3,600 lbs and most likely has a tongue weight of 360 lbs. My favorite powered jack to recommend is the Stromberg Carlson # SC63VR jack is rated for...

  • Replacement Motor for Ultra-Fab Electric A-Frame Jack 38-751040
    I spoke with Ultra-Fab and they said if the jack was made before 2015 then there are no replacement motors available. The serial number on your jack starts with 12 which means it was made in 2012 therefore, your only option is to replace the entire jack. The upgraded model is the Ultra-Fab Electric A-Frame Jack part # UF38-944017 which has brighter LED lights, an external ground wire for more dependability, and a more secure cover for better protection from the elements.
