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.

I installed this on a construction tool cargo trailer. This trailer is outfitted with solar and a battery bank so an electric jack was a no brainer since I already had plenty of power storage. I didn't want to install in the stock jack location so that I could fully open my truck's tailgate. I was able to find a bolt-on jack bracket from a different online store, which made for a easy installation without welding. The same electrician that installed the solar and batteries wired the jack into the elec system and he said it was slick. The trailer has several thousand pounds of tongue weight and this jack has no problem lifting it. The memory settings are handy. This saves quite a bit of time connecting and disconnecting. With the push of a button the trailer jack lifts or lowers automatically while I deal with the safety chains, break away cable, and 7 prong plug. Just as advertised it lifts very quickly even under load. It was installed about a year ago and it's still going strong. I give this a 5 star rating without hesitation. Strong, durable, and well made.

I LOVE this jack.
I cant stand pushing
a jack button and waiting forever for the jack to run up or down, I wanted something faster. This is it!!
No issues lifting my loaded race trailer, smooth operation, no standing in the rain for 10 minutes waiting for it to run up off the ball of the truck. Best accessory I ever bought for my trailer.
Definitely recommend!

My jack actually stopped working about a month ago. It had plenty of power, batteries charged, truck hooked up, nothing mattered, all it did was beep when you pushed the button. I called UltraFab and explained the situation. The woman I spoke to said that there were a couple of years that some had control panel problems. She immediately got me another jack shipped and I received it 4 days later. What a great company with great customer service!! A lot of companies would say youre just sol but UltraFab stood behind their product 100 I will forever be an UltraFab customer!!

@AndreenM It's always great to hear when companies stand behind their products. Thank you for the update.

I have had 6 trips with the Phoenix 4000 and it worked great for first 4 . Hooking up for 5th trip I pressed button to raise . Button lite up for a second then turned off. Trailer did not raise . I turned power off then back on hoping to reboot and it worked.
It failed again at camp . I used ratchet to operate. When I got home I found 30 amp fuse blown inside of camper . I replaced fuse . I also believe inline fuse provided was loose at spring so I replaced with30 amp blade style fuse . It has worked perfectly now and hoping it will continue.



by:

I like the Fast Jack and the memory function seems like it'll be great. It did get damaged during shipping but we're going to silicone it up and use it. Shipping packaging could be better.



by:

I'm on my fourth warranty replacement right now, the latest one has been redesigned to solve the problem I kept having with their control pads. Hopefully nothing else breaks but I have very little faith in ultra fabs designs. Their warranty on the other hand is second to none, call them up and they will get you a new one in the mail right away. At the end, their jacks were only lasting a handful of travels before they died so at that point I could care less what bells and whistles it has as far as memory settings and a remote, I just need to not get me stuck; the jacks kept malfunctioning and would randomly fully extend and stop responding. Imagine my frustration when this happened while driving and my stupid jack started scraping the road I had stop in the middle of the highway with no way to get it back down.



by:

Just installed the jack and compared to the one provided on the travel trailer, it appears much more robust. I purchased this jack for the extended warranty and the ability to manually extend and retract the jack with a socket and drill. The top of the jack was cracked upon receipt despite the foam padding. Ultra Fab was eager to send a replacement top at no cost immediately. Love the customer service.



by:

Easy install. Love the memory functions and speed of operation. Also, how can you beat a 10 year warranty?!?!?



by:

Very happy with the performance of this trailer jack.The speed is so fast and it has held up very well.

I have bought a few items from Etrailer and have found them to be one of the best company to do business with. When I have a question or a issue (which was my fault) they help me solve any problem I had.They have a very fast and very competent customer service department. I can't say enough good about them.

This Phoenix Electric Trailer Jack - A-Frame - 22-1/2" Lift - 4,000 lbs unit works great. It lifts my car hauler quickly, and with ease. Based on other reviews, I was unclear if the tailgate on my Chevy 2500 would fully open with this jack installed. I installed it with the controls facing to the drivers side to provide additional clearance. With weight on the trucks receiver, the tailgate just contacts the jack when opening, but will fully open. If the jack is extended, and the receiver / tongue is raised, it provides enough clearance to open fully without contact. I'm very happy with this purchase.

I have these jacks on my fish house so they have been used in -25F temps. The jacks work great and they are fast.

Still working as should but one jack sounds a little rough on retract.

@Richard Has the jack ever been over extended or retracted? Doing so can damage the jack. The jack is covered by a 2-year warranty.

worked great for 1 year, 4 months. I will be submitting warranty claim. the jack suddenly popped a fuse and stopped working. my electrician checked it and says it is an internal dead short in the motor. lucky me....

This jack does have a two year warranty and I will send over the warranty return instructions to you.



by:

I Love the speed of its raising and lowering. I loved the memory button. Haven't used my trailer all winter and when I went to hook it up, I pressed memory #1 and it raised up to the position to back underneath it. How cool is that? To me, this is the number one best jack on the market.



by:

Keep scrolling!
This jack has been replaced
twice now within a year. Thankfully Phoenix does send a replacement but having a 16' enclosed trailer stuck to your truck gets old quick. Also, the option to manually turn the jack by hand does not work when the jack freezes up



by:

THIS JACK IS BY FAR THE FASTEST AND MOST USER FRIENDLY.I WOULD HIGHLY RECOMMEND THIS JACK.



by:

Easy to install, works very well. Mounting the unit sideways to provide more clearance for the tailgate makes the light point sideways. All fasteners come up from the below which eliminates the possibility for rust. Nice design...



by:

Easy install. Other than the speed of this jack the best feature is you can mount the front of the jack facing the drivers side so you now have room to lower your tailgate without it hitting the jack.



by:

Very smooth and quiet operation, and seems to be plenty powerful for my trailer. Easy install and no issues after one year. Very happy with this jack.



by:

This is the best jack I have had (and I seem to have gone thru quite a few). It was a quick and easy install for a replacement and I have found it is the fastest jack to raise or lower my hitch. It is also one of the quietest I have ever used. Great for early morning packing and not waking up all the neighbors. :) The jack seems a lot stronger than other jacks I have used and better built with less plastic on it than most. Would definitely replace any manufacture supplied jack on a new trailer with this one again on a heartbeat!

I have had a problem with the switch on this jack. It was the first generation of the jack. I spoke with Ultrafab and they replaced the whole jack with a new one without any issue to correct the issue. I am very impressed with the Jack and especially the great customer service! Cant be beat!



by:

etrailer sent me a used electric jack that another customer returned because it was defective. I know it's defective because the the email between the customer and Greg S at customer service was inside the box. The box was obviously very damaged, taped in areas that were torn, had someone else's shipping label on it, and the jack was filthy. Byron H and Scott H (the two that gathered and packaged my shipment) should have to go remedial training on how to do their jobs. Every item I ordered was opened, there were multiple items just loosely thrown in with one heavy box bouncing around. Terrible experience with etrailer. Sucks when a company stops caring about quality and would rather just let customer service fix their issues. Way to ruin it for the customer!

I will have our customer service team reach out to you.



by:

This jack is amazing. Fast. Quiet. The memory is very useful. The extra mounting holes on the base plate allow you to spin the jack to place it so that the truck tail gate will not strike the head of it if you drop the tailgate. I highly recommend this jack.



by:

After only a few uses the jack quit working. First the memory settings kept getting "forgotten". I reprogramed them twice before they quite working altogether. I kept using it without the presets but later it would not go up and down. I had to use a wrench and the provided socket to to move the jack which was much harder than expected. While I was turning the jack it started running, ripped the wrench out of my hand, and the wrench handle put a hole in my propane tank cover. The manufacture replaced the jack at no charge but would not do anything about my propane cover. After using the 2nd jack awhile in now is making clicking noises as the tongue is lowering. It sounds like maybe there is a tooth missing on one of the gears. My tongue weight is around 1400 lbs so well below the rating yet the jack does not seem to be holding up well even though it is not use all that often.

Otherwise I do like the jack. It is fast and the memory presets are a nice convenience. I also like that the head is smaller than other similar units.



by:

Installation was very easy. Just pulled off the old jack and installed the new Phoenix. Wired it up an WOW!! This thing is FAST!! My travel trailer is 36' long. This operates it up and down like it weighs nothing! My old jack quit working 2 months out of warranty and it NEVER operated half as fast as this one. If the durability is as good as the operation this may be the best tongue jack ever! Being able to double click the up or down button for automatic operation is a great idea! If any problems arise I will try to update this review.



by:

One year anniversary of installing this on my Airstream Basecamp, works great and really makes life a lot easier compared to the hand crank that came with the trailer.



by:

The jack is very nice. We had an issue with the original; however, etrailer and the mfg immediately replaced it. As always great customer service!

  • Are There Trailer Jack Options That Allow You to Fully Open a Truck Tailgate w/ a Travel Trailer On
    Your truck tailgate hitting the electric jack on your 2022 Keystone Springdale TT is a pretty common occurrence. Unfortunately, I am not able to determine what jack you have from your RV information. But, I have listed a couple potential options. I am unfamiliar with the taller post jacks you mentioned and did not find much on them. The first thing you could look at, is if you can rotate the jack to face the side. This typically provides a couple more inches of clearance. A jack like the...

  • Is There a Replacement Motor for Tongue Jack on Forest River XLR Boost
    I do have some great full replacement options for you but the motors are not replaceable on trailer tongue jacks. There might be one or two out there which are but none of the dozens we carry ever have that option. Instead, I recommend the Phoenix Electric Trailer Jack part # UF38-944040 which is one of the fastest options on the market and it comes with a 10 year warranty. I have attached a video I did on this very same jack below.

That we can do with the Phoenix jack: - Phoenix Electric Trailer Jack # UF38-944040 This has a 4,000 lb lift capacity which is more than enough for your 7,000 lb car hauler trailer to use in the manner you described.

  • Recommended Fast Electric A-Frame Jack for 12K Trailer
    The Phoenix Electric Trailer Jack part # UF38-944040 will be an excellent option for a 12,000 lb trailer as it only needs to cover the max tongue weight which at 15% would only be around 1,800 lbs. This is one of the fastest jacks on the market with up to 10" of travel in 18 seconds. It also has an industry leading 10-year warranty.

  • Can The Phoenix Electric Trailer Jack Be Wired To The 7-Way Instead Of The Battery
    You could power the Phoenix Electric Trailer Jack # UF38-944040 by wiring it to the 12v accessory wire of the 7-way in your junction box, like part # 38656, instead of wiring it directly to the battery. There are pros and cons to this though. The pros being that the wiring is a bit more tucked away and less likely to corrode on terminal in the junction box versus sitting outside with the battery (if you don't have a cover). You'll also never have to worry about a dead battery since you'll...

  • Powered A-Frame Jack Recommendation for 5,600 lb Toy Hauler with Weight Distribution
    The higher the capacity of the jack that you go with the quicker it will raise and lower due to less straining but you could easily get by with a 3,500 lb capacity jack on a trailer with a 700 lb tongue weight. My favorite one to recommend is the Phoenix part # UF38-944040 which is by far the fastest jack out there as it extends in less than 10 seconds. This will make the process of jacking up and down to install your WD system much quicker and easier.

  • Options if an Ultra-Fab Phoenix Electric Trailer Jack Has a Bad Circuit Board
    Good news and bad news. There is not a replacement circuit board available for the Phoenix Electric Trailer Jack # UF38-944040. So if the circuit board goes bad, it will either need to be covered under warranty or you'll need a new jack. The good news is that the Phoenix Electric Trailer Jack # UF38-944040 comes with a 2 year warranty or all the way up to a 10 year warranty if you registered your jack within 90 days of purchase.

    It sounds like you're saying it is hooked up to power but it doesn't have the ability to raise the trailer. This could be the batteries or a problem with the wiring.

    To test your jack, I recommend first checking your trailer battery for proper charge.
