Hook up, check tongue weight, and get on the road with fewer steps. This kit pairs a 5,000 lb electric trailer jack with a jack foot tongue weight scale, letting you lift your trailer and verify the load during the same hitching process.
When you're getting ready to tow, it's hard to know if your trailer's tongue weight is right just by looking at it. Lower your trailer onto the gauge while it's still on your jack, see where the weight stands, move your gear if needed, and check it again before you hitch up. Because the scale replaces your jack foot, there's no separate tongue weight scale to deal with every time you check your load. Four mounting positions let you rotate the gauge toward the side that's easiest to read. If you use your trailer on gravel, grass, or other soft surfaces, the scale also works with the 6" Round SnapPad (SN47FR - sold separately) to help keep the jack from sinking.
The 12V motor raises and lowers your trailer with the push of a switch instead of a manual crank. The drop leg extends up to 4-1/2", helping you get closer to the ground before using the motor. A built-in LED lights your coupler when you're hitching up before sunrise or after dark, and the included manual crank keeps the jack usable if electrical power isn't available.
Moisture takes a toll on trailer jacks, so this one uses weather protection to help limit damage over time. The jack is made of black powder coated steel to help resist rust. Weatherproof buttons and the rubber cover over the manual crank opening help keep moisture out, while the included canvas cover helps protect the jack during storage. The 20A automatic reset relay fuse protects the motor from overloads and short circuits.
This jack wires directly to your trailer's 12V power source, so it doesn't rely on your vehicle's 7-way connector for operation. Top-mounted controls keep operation straightforward from the jack housing, and the automatic reset relay fuse resets itself after an overload or short circuit instead of requiring a replacement fuse.
Note: This kit is recommended for A-frame trailer jacks only. The included tongue weight scale fits most A-frame trailer jacks with a 2" diameter inner tube and an interchangeable foot.

Had all the necessary hardware needed for install on a 20 year old trailer.Had to drill old bolts out due to bolts breaking then used the hardware supplied to secure the a frame jack to the trailer. Had to adapt and overcome the wiring connector was too small for battery top post connector but made work. Picks the camper up with ease thank you e trailer
Seems to be well built (time will tell) but everything I have purchased from etrailer has been very reliable. I’m sure this unit will be no exception. Easy to mount and works as advertised.
Jack and weight scale are great, very useful combination. The only reason this doesn't get 5 stars is because the ground wire is significantly shorter than the positive wire. I was able to run the positive wire back to my 12V terminal block under the chassis however, the ground wire is far too short to run back under the chassis and connect to an existing chassis ground. So, I had to drill a new chassis ground near the A-frame, which was annoying.
Electric jack arrived in two days. Old jack sheard so couldn’t get the trailer off the truck so the arrival of the new jack was very timely. Install was easier than expected. I’m not the most electrical savy person, but once I removed the ground to the jack there was no power so cutting and splicing in the new power went smooth. Just wish the new jack had the 12awg splices included. Would have saved me a trip to the hardware store. Would have been a real problem if I had to do this on the road.
I bought a jack a little over than a year ago at a tool supply store and it went bad. I hated the jack because it did allow the tailgate to come down. I installed this new jack from E Trailer and my tailgate extends all the way down. This is excellent to get into the bed during camping setup or tearing down. More companies need to design their jacks according.
The new etrailer electric jack works great on my RV. Took a little time and a phone call to figure out the directions for the power hook up but it is working and was very simple to install.
Just installed it. Jack went on fine, bolt holes matched my 20’ Haulmark enclosed trailer exactly. I had to run power to the battery, and that took the longest.once connected, lifted the trailer right off my floor jack. Now I just need to tuck and zip tie wires.
Fast shipping, easy install, works great
Brittany was a great help to find ensure the product I selected was compatible with my trailer. We checked the stroke an capacity, discussed installation. The e trailer brand jack I chose arrived the next day, was easy to install and it worked. I'm still looking forward to using it "on the road" but have confidence there will be no issues.
E Jack is a great conversion. I didn't put a battery on trailer to run it. I simply used RV flat pin receptacle and used ground and power post, runs jack fine and you do not need vehicle running to use jack
Installation was a breeze and so far it is working as advertised. Very happy with the product
Unfortunately the casing can not be opened up with out destroying it. I thought I would be able to wire it up with the existing trailer hot wire directly to the mower, but ended up have to splice into the camper wire harness. Not what I wanted, but made it work.
Bold holes lined up on my Winnebago Minnie 2500rl perfectly. Received unit, mid day, mounted, and did electrical all in the same day. I also like having the internal circuit breaker rather than a "burn out" fuse. Storage cover is a nice touch too.
Installation was fast and easy though it's a drag the the ground wire is designed to be too short to reach the battery. Fastening it to the frame in an area sheltered from dirt and moisture is easy enough but it's the step that took the longest.
The unit is much quieter and faster than the Domestic it replaced. I didn't really want a drop leg because my old lady arthritic hands don't need another little fastener to deal with but it seems that it will work well.
I like the larger base and the protective cover over the controls. It has everything I need and none of the extras I don't. So far I'd recommend it.
This is a great tongue jack, super easy to install. And most importantly, it's dependable! It's been so dependable that I don't even think about it, that's a great thing. If it has one downside, it's the speed, it's slow. But I get torque (lift power), speed and battery drain all have to work together, you can't have everything. For example; if you wanted faster speed with the same motor, you could just reduce the gear-ratio but then it would no longer be rated at 5000lbs, it would be less. Put on a bigger motor to get the torque (lift power) back to 5000lbs and you'd have more battery drain and so on. This jack has a good balance of those three things. I'd definitely buy this jack again.
This trailer jack works great! I set mine up to run off a small 30amp hour lithium battery that I store in the tongue box. It works great, and I can level and make adjustments without having to connect to my truck. The jack works quietly and quickly.
Superb! Operates nice and quiet compared to my factory model. Installation was a breeze. Price was amazing. I do encourage others to get one, because it operates smooth and quiet. The smaller design over the factory one allows more space for the tailgate operation as well.
I was assisted in a chat session on a Sunday afternoon. I gave the representative the model number of unit that had to be replaced and in less than a minute was told that this unit is an exact replacement. I immediately ordered it and it was shipped that same day. The the e23ZV is a perfect replacement for the Jayco Jay Feather Micro 199MBS. Fits nicely under the tongue mounted bike rack. I already installed it and it performs perfectly.
I really like my new electric jack. I got the 3500lb capacity which matches my oem jack. Iwas going to get the 5k but i decided to stick with the 3500lb. And i have been happy so far. I have a ST2916 stryker toy hauler. The tounge weight can get close up to 2k lbs. The jack handles my application like a champ. I usually have to lift the jack high enough to facilitate the install of the stabilizer bar, so it essentially starts raising the truck a bit. No issues so far. It actually actuates faster than the 3500lb lippert oem jack I previously had on. I like how it has an extension at the foot. It's very practical. I also like how the toggle switches are located near the top of the jack. My lippert oem has the toggle switches on the front of the jack facing the tail gate. I had to be careful not to hit or bump into the toggle switch as I moved/jump over to the other side. I did end up breaking toggle switch once becausei bumped into it. That was an expensive fix.i don't have to worry about that now.
The only con that I can think of is that the trailer does seems shake a bit as I'm retracting or lowering the trailer. At least more than I'm accustomed to, but it hasn't been an issue so far.
So far I'm happy with the jack.
Jack is plenty good, seems well designed and built plus the cover actually feels heavy duty compared to others. Installed on a race trailer since we had a battery in it for the winch so why not. Welded a piece of 6" C channel into the A of the tongue close to the body so the truck tailgate would clear it. Drilled the holes out further than typical so didn't have the mounting problems others had with washers not sitting flat. The reason for the 4 stars is why in heaven's name the ground wire couldn't have been the same length as the power wire to reach a battery without soldering in an extension?!? Not a show stopper but geez- I'd have paid the extra buck for 2 more feet of wire. For anyone reading this and wondering no, I purposely did not ground the battery to the trailer, less problems going direct to the battery for high-draw stuff.
This jack install was quick & easy. I like that the hardware includes plastic inserts lock nuts, needed or not, I used them. My 25 Expedition doesn't provide enough amps without putting truck electronics in jeopardy. I'm not interested in having an on-board trailer battery, so I wired up connections for a jump starter. Works like a charm numerous times on single charge. I have EXACTLY the setup I was aiming for. Love this jack!
I don't have a photo yet, however, it is installed and works great. I really like knowing what my toung weight is it allows me to adjust as need for better towing.
Fast shipping. "NOT FEDEX" thats a bonus. Excellent service by ETRAILER.
Received it today and it was an easy install. The jack seems very sturdy and easily lifted the 1200 lb. trailer tongue. I used the tongue weight scale, which was very easy to put on and take off. The weight display gauge was easily readable. The jack is a compact design and, with the weather cover, seems like it will be well protected from bad weather.
