Features to know about

Lifts Your Trailer Without the Effort: Electric Power and 3,500-lb Capacity

Cranking up a heavy trailer by hand gets old fast. This electric A-frame jack does the lifting for you with a push of a switch. It’s rated for 3,500 lbs of lift capacity, giving you plenty of power to manage even loaded trailers without strain. With 19-1/2" of screw travel plus a 5-5/8" drop leg, you get a full 25-1/8" of total lift—enough range for hitching, unhitching, or leveling at camp.

Simple Power Connection: 7-Way RV Plug for Quick Setup

No need to hardwire or install a separate battery just to run your jack. The built-in 7-way RV-style plug draws power straight from your tow vehicle’s trailer connector. Plug it in when you need to lift or lower, then swap back to your trailer’s plug when you’re ready to roll. It saves time and avoids wiring hassles while giving you dependable electric power at every stop.

Works Day or Night: Two Toggles and a Downward LED Light

Late-night arrivals or early starts aren’t an issue thanks to a built-in LED light that shines down on your coupler where you need it most. Two toggle switches make operation easy—one for the light and one to extend or retract the jack. If power ever goes out, there’s an emergency crank included so you can still raise or lower it manually.

Built to Last Outdoors: Steel Construction with Corrosion Resistance

Rough weather and road grime are part of towing life, but this jack is ready for it. The outer tube has a black powder coat finish while the inner tube and footplate have zinc finishes to resist corrosion. A sturdy pin and clip secure the drop leg in place, and installation is simple with its bolt-on mount and standard 3" A-frame pattern.

Compact Height with Solid Clearance: Fits Tight Spots without Sacrificing Lift

Even with its full range of motion, this jack stays compact when retracted. The bracket height measures just 9" in the down position and extends up to 28-1/2" when raised. With 20-1/2" of clearance from the bottom of the bracket to the top of the housing, it fits neatly under propane covers or storage compartments while giving you reliable lift every time you park.

Haven't installed yet, but order process was great. Ron



by:

So far great jack, terrible plug. The quality of the plug itself is very low. Considering this price point, these jacks should come with a keeper for the plug, especially when it's guaranteed they'll be 2 trailer plugs with this kind of set up.

I had to change the pin-out inside the plug for my superduty to get red on a 12v pin, not a big deal the plug comes apart quickly.

I ordered a replacement plug and a keeper that mounts on the jack already.

Would give this 5 stars if the plug was better.



by:

The top housing was broken in transit, light doesn't work. Jack works fine. Would like a replacement



by:

Last summer we bought a new truck to tow a new concession trailer. The differing heights of the two vehicles, along with the pitch of our driveway made it impossible to unhitch our trailer. We purchased this power jack hoping it would help. This jack allowed the tongue of the trailer to raise higher to allow the ball of the hitch to release. The ease of pushing a switch compared to cranking it by hand makes it worth every penny we spent to get this jack. I found the prices at etrailer to be far better than anywhere else I looked for this item. Great customer service sealed the deal.

I hit the wrong star. Both items are working perfectly!! Should be a five star rating.

Very easy install. Works amazing. I love the 7 way plug that powers it. Very simple to use.

Easy installation - Less than 20 minutes
Really
quiet operation
Love the product in less than 5 minutes

Did not fit .Sanded the power coat down trying to get enough clearance Clarance haha and it still doesn’t fit so close so I guess I will sand some more. What is odd is that this is specific for my camper as per previous question as to fit.Paint remover maybe offer any suggestions
I already have over an hour in this and it still isn’t installed.
Thanks



by:

Arrived on time, no damage, instalation under 30 minutes, works as advertised. Only issue was the 'stop here' tape near bottom of the shaft was skewed. I know from past experience not to lower the Jack all the way down but am awaiting a reply from my email asking for info on exactly what point I should not lower the Jack. Other than that, I am very satisfied with the product.



by:

This is a good little jack! It came from etrailer quickly, installed easily, and works great! As usual, the folks at etrailer were a pleasure to work with!



by:

This jack works awesome! Even slipped off the block once and it didn't even phase it. Good heavy duty build! Crane operator/Trk driver



by:

incredibly easy to install and works gr eat.



by:

So far so good! I really like the 7 pin pigtail, eliminates cutting into the trailer’s wiring harness. Clean and tidy in appearance.



by:

After a year still works great……easy to install, and didn’t need the light because I had already installed a rear utility light to my truck to hook up trailers but for those who don’t have a back light it is much easier than a flashlight. Great product!

After two years still working great. Only issue I had was the cap on top of the unit which exposes the manual crank connection is poorly designed and doesn’t tighten which eventually blew off. I found a cap that would screw on and tighten.

@Ron Hey Ron, thanks for sharing! Glad to hear your jack is still serving you well. Come back anytime you need anything.


by:

The 7-way plug electric jack is a great replacement for my crank handle jack. I did not want to install and maintain a 12V battery for just a jack so this is an easy plug and play solution for me.



by:

Installed this today on a cargo/work trailer that I pull with a 19 f250, install wasn't bad, except for the trouble shooting. Just happen to notice they had one with a 7 pole wire, which I got so it'd work off my truck(since I have a cargo and no batteries), I'm pretty mechanically inclined and started troubleshooting what the issue was as soon as it didn't work. I had to change terminals for the hot wire to my parking light terminal, only way it'd work. Other than that, works amazing and regret not getting one sooner.



by:

It doesn’t work have the time.. not sure if it’s grounding to the hitch or not. Usually end up using the hand crank.

Hey David! Have you been able to do any troubleshooting? I think checking the ground is a good place to start if you haven't already.



by:

The jack works great only problem is if you have a truck that has smart tow like my F150 you’ll have to have another means to get power to it because the trailer has to be plugged in and recognized before you get 12 volt power to plug, a battery or an auxiliary plug, which I had in the box of my truck for camper other trucks that have plugs have a designated 12 volt pin. The other thing was light went out



by:

Fast, efficient shipping with good communication and easy install.

Ordered on Friday at 4:00PM. Shipped on Friday and arrived on Monday afternoon. Great service and quick shipping are what you can expect from etrailer. I installed the jack on a 7x14 cargo trailer that I use to haul misc. equipment and materials with a 2018 Ford F350 DRW using a Curt 48012 pintle/ball combo hitch. Once the old jack was removed, installation was very easy. I did however have to make a modification to the jack. My tailgate would not clear the jack when mounted in its intended position. With kids and misc helpers that is a no go for me. After looking at the jack, I removed the 5 screws holding the top cover on and noticed there are 4 socket head bolts holding the gear box onto the jack body. I removed the bolts, rotated the gear box around to the back of the jack and reinstalled. This position provides me clearance for my tailgate and protects the switches from potential damage. It does put the light on the wrong side to be useful, but as the etrailer employee said in the video, “its not the brightest light” to begin with. I have only used it a few times to confirm operation but so far it works well and sure beats the old jack I had on there. etrailer has great customer service and technical support. I would recommend this product to others and will continue to shop at etrailer. Thanks!



by:

Jack works just as described. Use it daily on my 16' enclosed box trailer full of tools and equipment. No matter how cold outside the jack works perfectly. Highly recommend the product.

  • A-Frame Jack Recommendation For Keystone Hideout 24BHWE
    Hi George, I see you've been interested in adding an electric A-frame jack to your Keystone Hideout 24BHWE since at least 2020 when you first asked, so hopefully we can get that resolved today so you can very easily raise and lower your trailer. Since your trailer has a GVWR of just under 7,420 lbs and a jack will only lift up - at most - 15% of that weight, capacity is not going to be a factor at all. With that in mind, there is one option that I absolutely like more than the rest, which...

  • Can I Rotate the Electric Jack w/ Footplate and 7-Way Plug on the Trailer for Tailgate Clearance?
    Hello David, Great question. The Electric Jack w/ Footplate and 7-Way Plug - A-Frame - 25-1/8" Lift - 3.5K - Black # EJ-3527-BBX uses the standard 3-bolt A-frame mounting pattern, so you can rotate it for better tailgate clearance. Because that bolt pattern is symmetrical, the holes will still line up if you turn the jack in 120-degree increments. That’s actually a pretty common way to gain a little extra space, especially with trucks that have tighter tailgate clearance. The main thing...

  • Is The 7-Way On The Electric Jack EJ-3527-BBX The Same As A 7-Way On A Trailer?
    Hello Maria; yes, the 7-way plug on the Electric Jack # EJ-3527-BBX is the exact same as the 7-way you will find on a trailer. The vehicles 7-way just needs to have an active 12v pin to power the jack.

  • What Is The Total Lift Of The Electric Jack w/ Footplate EJ-3527-BBX
    Hello Maria. The 25-1/8" measurement is the exact amount of lift the Electric Jack # EJ-3527-BBX provides. The screw travels 19-1/2" and the drop leg travels 5-5/8". It has a retracted height of 9" an extended height of 28-1/8" and an outer tube diameter of 2-1/4". Your best bet will be to compare these measurements to the trailer and/or the current jack to make sure it will fit.

  • Can I Power the etrailer A-Frame Jack Through the 7 Way to Pull Power from Towed Battery?
    Hello Kyle, Yes, our etrailer Electric Trailer Jack - A-Frame - 18" Lift - 3,500 lbs # e23ZV would be an excellent fit for your 2-horse trailer at 3,000 pounds. A 4-flat trailer connector only carries lighting functions (tail, turn, brake, and ground), so it does not provide a 12V power source and therefore cannot be used to power an electric jack. To run the jack from your tow vehicle, you’ll need to use the 7-way connector, which includes a dedicated 12V auxiliary power circuit. Connect...

  • Can etrailer EJ3527-BBX Trailer Jack Be Powered From 7-Way Trailer Connector on 2020 Ford F-150
    The etrailer brand # EJ-3527-BBX is equipped with a 7-way plug that technically can be plugged into the 7-way trailer connector on your 2020 Ford F-150, but it will not function due to the "intelligent" towing package these come with now. This makes your towing functions only operate when your truck detects a trailer with electric brakes. This being said, your best bet would be to install a battery on the trailer and run a powered jack from that. The etrailer # EJ-3520-BBX jack is designed...

Since you mentioned the 7-way I believe you also want one that simply plugs into the truck's 7-way which will make it easier to power on and off. For that, what I recommend the Electric Trailer Jack w/ 7-Way Plug - A-Frame # EJ-3527-BBX. This has a 3,500 lb capacity, which is more than enough for a medium-sized horse trailer, and as far as quality, this is a highly-rated jack,...

  • Why isn't There a Wheel Caster for Electric Trailer Jacks
    Hey Marius, there isn't a wheel available for the etrailer electric jack part # EJ-3527-BBX that you referenced which is pretty normal for electric jacks. The reason is the wheels end up cutting the capacity of the jack by about a third and most trailers that have the need for an electric jack (heavier ones) are too heavy to be pushing around on a wheel.

  • Recommended Electric Trailer Jack For A 14,000lb Dump Trailer
    The rule of thumb for determining tongue weight is to calculate 10-15% of the GVWR for the trailer, with yours being 14,000lbs we'd be looking at a tongue weight of roughly 1,400 - 2,100lbs. With a jack you can always go heavier though, and the heavier duty you go the easier it will be for the jack to lift the tongue of the trailer. The etrailer Electric Jack w/ Footplate # EJ-3527-BBX you were looking at is rated for 3,500lbs, which is well over what you'll need, and is designed to be...

  • Recommended Trailer Jack For Trailer With 14000lb GVWR
    Since you are limiting your trailer to 10000lbs, and the average tongue weight is 10-15% of the trailer weight, you are looking at 1000-1500lbs tongue weight. With that said it is a good idea to use a jack with a larger capacity as it will be able to work easier leading to a longer life of the jack. I recommend the Electric Jack w/ Footplate and 7-Way Plug # EJ-3527-BBX which has a 3500lb capacity meaning it would be able to work fine even if you loaded the trailer to 14000lbs and had...
