Video Transcript for Stromberg Carlson Electric A-Frame Trailer Jack Review

Today we're going to take a look at and show you how to install the Stromberg Carlson a-frame electric trailer jack. This offers a drop leg with 18" of lift and a 3,500 pound capacity in white. Its part number is JET-3555. Now with both of our jack and drop leg in the highest position we're going to have a bracket height of about 32-3/4", so right up here to our flat mounting location it's going to be about 32-3/4". Now the drop leg adds 5", so we'll actually be able to roll that back to about 28-1/4" if we prefer to have our drop leg in its highest setting, and anywhere in a 1-1/2" increment between there. Now with our jack in its lowest position and our drop leg in its highest position we're going to have a bracket height of about 13-1/2". If we reduce our drop leg to its lowest position that's going to subtract 5". Now you're going to have waterproof switches here on the front that are going to control both the up and the down.

Now it's interesting to note that the up means your trailer tongue will go up. The down means your trailer tongue will go down. On the other switch here we're going to have full control of the two lights that we've got on either side, are a nice soft blue light. They're going to light up plenty of space. It's on a 180 degree lens there, so with that it's going to spread the light out over our coupler area and also back if we have any kind of weight distribution setup that we need to manage, we should have some light shed on that as well.

We got one light on each side, which is really nice so you can work on both sides of the trailer. A simple on and off operation with our switch. We're also going to have have a white weather-resistant cover here. It's got a nice snug fit around. Most of the joints and everything look pretty clean. That's going to protect all of our electronics that we've got up here.

All of our soldered wiring is going to be protected by our housing. We've got an external motor here so that's going to help some airflow come across it and help cool it off in the event that we're really using it a lot going up n down. We've got an inline fuse holder here. This is going to protect the wiring on our trailer and also protect the wiring in our motor so we don't have any kind of excessive voltage running through. Another great feature if the application calls for it will be the bubble level that's offered right on top of the jack. As we work it down it will come to the level position, indicating to use that we've got our trailer set properly.

Now the level area also acts as an access point for us to get in in the unfortunate event that we would have some kind of a battery failure. We've got an o-ring that sits right around the top that seals that off really well. We can just slide our accessory wrench right down in. That's going to easily allow us to raise or lower our trailer in that event that we have a failure. Now this won't cause any kind of damage to the motor or anything like that. They've designed it so we can use it this way without causing any kind of issues. Uses just a standard inverted hex bit there. It will go right down in there and really allow you to adjust it if necessary. Place our o-ring back in, line up our tabs, and rotate this right on into position. Perfect. Nice and sealed back up. Now to give us a good long-lasting product, there's a few steps that they've gone through to get us there. First, the cover up here is a molded plastic but it's then painted. That's going to give us that reduced yellowing effect that we sometimes see from white plastics. The outer tube here, complete black powder coating finish so very rust-resistant. Also a very durable finish, stronger than what paint would be. Once we get to our inner tube and our drop leg these are going to be completely zinc coated so we'll have superior corrosion resistance there as well. That's going to keep everything looking good. Now to keep it operating well, use a high strength screw inside here, which does have a clutch that's going to limit the force being able to be applied to it so we won't have to worry about overworking it or overusing it and causing undo stress and friction that will ultimately shorten the life of our jack. Now we can take advantage of the easy bolt-on application sites, or because we do have a nice thick steel flange down here, this could easily be weld-on as well and just paint over those welds to match your trailer and jack. Now we're going to begin the installation with our existing jack removed. That's going to open up the 2-1/4" hole here that we're going to require. Also it will give us a good look at the bolt holes that we've got. Now we want these to be about 3" on center, so from the center of one to the center of the other we want it to be about 3" there. Then we can drop our jack down into place. That 2-1/4" hole is going to allow our 2-1/4" outside tube to slide right through. While you've got a good look at it, your inside tube has a diameter of 2" just so you have that for reference for any kind of accessories or anything. Then we'll simply just drop it right down into the hole. Now with our bolt holes lined up we're going to use our existing hardware as long as it meets specification. That's going to be a 3/8" bolt that has a grade five hardness rating. What we'll do then is place underneath the washer one of the serrated washers that are going to come with our jack. These are meant to go under the flat washer. They're going to scrape or abrade the paint as we tighten it down. That's going to provide us with a really good ground location. Let's get our three bolts started. Now we'll leave each one hand tight initially. We want to be sure that if we need to wiggle our jack around a little bit or move it to line up the holes that we'll have that adjustability. Now with those started we'll use our wrench, and we're going to tighten them on down. Then we'll torque them down to the specifications that are listed in our instructions. That's going to take care of the mounting. It's nice and secure. Now let's do the wiring. First thing I'm going to do is to separate the yellow fuse holder and pull that fuse out. We'll put that in at the very end just to protect our circuits while we're doing our wiring. You'll have a good length of wire here that we'll be able to use to run to either our battery or a 12 volt power source on our trailer. Now we'll run this back through our trailer. If there's any tie-down locations or anything like that we can use, we'll use those. Just bring it back. We want all of our wires to be snugged up against our frame rail so we can use some zip ties or some other hardware and take care of that later. This is our 12 volt power wire that runs from our trailer. This is the one from our jack. We're going to use a butt connector, slide it on the end of our jack wire, crimp it down, pull on it real hard just to make sure you get a good connection, and then we can strip our 12 volt trailer power wire. With that stripped, we'll slide that right on and crimp it on down. Now let's just take our wire. As you can see, I got a little bit of excess from the trailer, a little bit of excess from the jack. Let's just bundle this together. Then we can secure this off to any good connection point underneath our trailer and just bring that down. The little bit of extra that we have here will be great for keeping the slack off of our fuse holder and that here, so just pull that up to give us just a little bit of room there, and we'll zip tie right around the main shaft. Now let's place our fuse back in the fuse holder. Now with that connection made we can just tuck it around here to the back side. One more zip tie should have us all set. Now we're going to put our drop leg back in place. As you can see, the drop leg itself is going to have a 5-1/2" diameter plate. That's made to spread that energy out over a greater area so it's not focused on just the smaller portion of our inner tube. We've got adjustments here for a total of 5" and an 1-1/2" increment as we go up and down. What this allows us to do, instead of our foot pad here being all the way in the up position and our jack having to go all the way down, we can bring this right on down and then pull our bale clamp right around the outside. You'll also notice here a "Stop, do not retract beyond this point." You don't want to go beyond the top of that white line as you're retracting your jack, so it gives you a nice visual cue so you know when to stop. Now that we've seen how it works and how to get it installed, that's going to complete today's look at the Stromberg Carlson electric a-frame trailer jack, part number JET-3555. .

Stromberg Carlson Electric Trailer Jack - Drop Leg - A-Frame - 24" Lift - 3,500 lbs - White - JET-3555

Average Customer Rating:  4.7 out of 5 stars   (51 Customer Reviews)

Use this electric tongue jack to lift your trailer with the flip of a switch. The sturdy steel jack can handle up to 3,500 lbs. It has 19" of travel and a 5" drop leg for extra lift. LED lights on both sides boost visibility at night.

After a year of use, I am still very pleased with my electric Jack. It moves up and down at a good speed. It handles the 700 lbs of tongue weight of our travel trailer with no struggle. It is relatively attractive compared to some others. The white cover matches the propane bottle cover behind it. My only complaint is I wish the lights were a little brighter. They are better than fumbling with a flashlight in the pitch dark, but just not as bright as I had expected. All in all, I am very pleased and would buy another without any reservation. 353846

I purchased 2 of these a year ago to replace a hand crank on a cargo trailer. I wanted to modify the tongue of a trailer where the crank was in the way of loading and unloading a work van. The push of a button, in this case two, is way easier and much faster than old school hand power. It worked out so well, I did a dump trailer as well. Then, a friends trailer. I might be starting a trend. 486187

I had this jack on my last trailer and I liked it. It is nice that it has a level as part of the cover to get you close. My trailer is 5,500 lbs and this jack has no issues with lifting the tongue. I do not like the glass fuse and holder that comes with it. The same fuse holder failed on my last trailer. So when I ordered this one for my new camper I stopped by the auto parts store and got a good quality sealed blade fuse holder. I thought I had read that this did not come with the mounting bolts. It does. I used longer bolts with additional fender washers and lock nuts. Ordering from etrailer is the best. It was convenient, easy, and the price is really good. 525391

Product was conform to description, easy to install and work great, I completed installation in less than 30 minutes. 487556

My Stromberg Carlson power jack is still working well. As for all my belongings I take good care of it, that should make it work for a long time I hope...

My existing jack is unreliable and the new product should do that for me. 671228

- JET-3555

Again, I purchased based on price. I liked the price but I can see now that you get what you pay for. This thing works great. However, it does not sound great nor does it have a solid feel to it. I got a great product for the price but at this price it is not what the more expensive jacks are. 663565

Works great. Saves me a lot of energy hooking up weight distribution hitch. 662170

- JET-3555

Love it!!! Good jack and a better price, couldn't be happier... 661241

- JET-3555

Put it on my trailer last year, used it twice camping last year and went out for the first time this year and it doesn't work!! Had to use the hand crank!! 660499

The first step in troubleshooting is to check that the jack is receiving power from the trailer mounted battery, and to check the power connections and the battery ground to the trailer. Youll also want to make sure that the spot where the jack bolts to the trailer tongue isnt corroded, as corrosion will interfere with a good ground connection. The jack is covered by a 2 year warranty, so if the items I mentioned above check out okay, please contact our Customer Service folks at 800-298-8924.

I installed this Stromberg Carlson electric jack about a year ago. Installation was very easy (I installed it while hitched to tow vehicle - don't use your stabilizers to hold your up your trailer weight). The jack worked great on several outings last year - great time (and back) saver when setting up. However, we just bought a bigger trailer (used) and I wanted to swap this with the factory electric jack on the new trailer. The dealer agreed it was a good jack but he wouldn't let me swap. Oh well, I'll probably be replacing that one with another Stromberg Carlson soon. Also, I found the best price here of all vendors when I initially shopped for it. 635527

- JET-3555

All as described. Shipped quickly. Install went quickly and without a hitch. Electrical connections included. 614435

- JET-3555

Looks good, everything fit like it should. Raises and lowers my 26’ Attitude toy hauler easily. Replaced original after 13+ years cause the gears were starting to slip. Went to a 3500lb from a 2500lb just cause I could. They need to put a clearer lens so the light would be brighter. Overall pleased with this purchase. 593313

- JET-3555

This product arrived within a couple of days after ordering. It was in good shape and ready for installation. It was an easy, quick install and works very well. I am completely satisfied with this jack and will probably order from etrailer.com again. 580665

- JET-3555

The installation was easy and the new jack works very well. Better than the original. The only problem - No wire connectors or fuse in the package. Had to buy some at local hardware. Enjoyed the fast shipment. Will be using this week on a fall trip to Vermont 569640

This Jack works Great. Installation was simple. The easiest and safest way to install the Jack is to attach the trailer to the tow vehicle. It’s so easy to operate and use. 498155

Love our jack! Lifting out trailer just got so much easier! Now if only the jack removed grease from the hitch ball! 494167

the only issue I have is that it did not come with a cover. 460366

I purchased this jack over a year ago for my 27 ft Sandstorm Toyhauler. Max weight is around 10,400 lbs. It was easy to install and a great price. After a year it is still operating 100%. Great packaging on delivery and great product. 458901

Requires 2 sets of hands to install, but it was easy! Haven't been camping yet, but so far it works great. 452147

Ask the Experts about this Stromberg Carlson Camper Jacks

  • Do All A-Frame Trailers have Same 3 Bolt Pattern for Trailer Jacks
    Yes, basically all A-frame trailers are going to have the same bolt pattern for installing a trailer jack. Typically the jacks have mounting holes that are somewhat slotted too to help with some variances. The bolt pattern you mentioned having on your trailer is compatible with the Stromberg Carlson Electric Trailer Jack # JET-3555 so this will work great for you.

  • How to Wire the Stromberg Carlson Electric A-Frame Trailer Tongue Jack, # JET-3555
    The Electric A-Frame Tongue Jack, # JET-3555, runs off a 12 volt battery. The best source for power would be from a 12 volt battery (like a car battery) mounted on the trailer. If you have a separate battery mounted on the trailer, a 7-Way trailer connectors 12 volt circuit can be used to maintain (but not up charge) that battery.

  • Troubleshooting Powered A-Frame Jack Not Powering Up or Down with Flickering Light
    Sounds like a weak battery powering the jack, or the wiring of the jack isn't solid enough and you have an intermittent connection. So check to make sure the battery of the trailer has a solid charge, and then next check the wiring connections of the jack noting that it grounds through the mounting hardware so it needs the mount needs to be clean between it and the trailer frame.

  • Troubleshooting Working Lippert Powered A-Frame Jack Manual Override that Feels Stuck
    I called our tech contact at Lippert and he said that the manual override of the older style A-frame jacks that they carry do not like to operate if the power source of the jack is active. Basically if the jack is functioning fine with the switch it will not want to operate with the override. You can try disconnecting the power source to see if it will function.

  • Recommended Electric Trailer Jack Compatible with Coachmen Clipper 17BHS Coupler
    The Stromberg Carlson Electric Trailer Jack # JET-3555 has the larger outer tube diameter as you mentioned. I recommend using a rotary tool like a Dremal to enlarge that hole. Another great option is the Bulldog Powered Drive Trailer Jack- 22" Lift - 4,000 lbs # BD500199. This has an outer diameter of 2-1/4 inches which is even slightly larger and this is actually the more standard measurement for most jacks. You will need the rotary tool to enlarge the hole for this one as well.

  • Why Would a Powered Trailer Jack Only Work When Connected to Tow Vehicle
    The Electric A-Frame Tongue Jack # JET-3555 grounds through the mounting bracket of the jack. If your trailer isn't hooked up to your tow vehicle when you are trying to use the jack the problem would be that it isn't grounding properly. If you run the ground of your trailer battery to the trailer frame it should work.

  • A-Frame Electric Trailer Jack Won't Run but the Light Works
    If the jack light is working but the motor won't that means that the jack is getting power so we can rule out the fuse/breaker being the problem. It is possible that the battery the jack is connected to has enough power to run the light but not the motor. The battery may need to be charged or replaced. A local auto parts store can test the battery. Another possible cause is a weak ground. The light doesn't need to have the best ground but the motor which draws more amperage does need...

    The Electric A-Frame Tongue Jack, # JET-3555, runs off a 12 volt battery. The best source for power would be from a 12 volt battery (like a car battery) mounted on the trailer. The red power wire on the Electric A-Frame Tongue Jack, # JET-3500, is the power wire and it will attach to the positive battery terminal on your trailer battery. First, remove the fuse in the in-line fuse holder on the red wire. Mount the jack to the trailer and tighten it down. The jack grounds through the mounting...

  • Troubleshooting Electric Camper Tongue Trailer Jack that Just Clicks Instead of Raising or Lowering
    Before you replace the jack make sure the jack is grounded properly to the frame of your trailer, also check to make sure the main ground of your trailer connector is attached to a clean metal surface. Also check to make sure the 12 volt battery you are using has a good charge as it sounds like the jack isn't able to get enough amperage to operate when under a load. The jack sounds like it's making the same sound a car starter will make when the battery is either dead or the battery...

  • Will the Stromberg Carlson Electric Jack Replace a Jack that has a Triangle Mount Flange
    Yes, the Stromberg Carlson Electric Jack, # JET-3555, will fit on your trailer's A-frame jack mounting hole. A-Frame jacks are all the same size and have the same bolt-pattern. The manufacturers did this so they could simplify the manufacturing process for both bolt-on and weld-on A-frame jacks. The mounting bolt holes on the Stromberg Carlson jack measure 3 inches from center to center.

  • Can an A-Frame Jack be Rotated on the Trailer for Hatch Clearance
    You can rotate an A-frame jack like the Stomberg Carlson Jack part # JET-3555 that you referenced if needed to allow you to open your rear hatch. The bolt pattern of the jack is allows for mounting of the jack in any orientation.

  • Maximum Traveling Height of the Electric A-Frame Tongue Jack # JET-3500
    If the Electric A-Frame Tongue Jack # JET-3555 is lifting to it's maximum travel distance of 18 inches then the jack is working fine and you just have too tall of a setup for this jack to work ideally for. Putting down a FloTool Jack Stand part # FT11933MI would take up some of this room. If it's stopping short then there is an internal problem. If internal components were to fail, replacement of the jack is the only option.

  • Size of Socket on Electric A-Frame Tongue Jack # JET-3500 for Manual Operation
    The Electric A-Frame Tongue Jack # JET-3555 that you referenced has an override nut on the top of the jack that will take a 3/4 inch socket.

  • Troubleshooting a Electric Jack that will Extend but not Retract
    It sounds like the switch in the jack is bad and should be replaced. Typically when an electric jack will go one direction but not the other its because the switch is broken. You might try checking all the fuses on the jack also. Since your trailer is brand new I would imagine there is some kind of warranty that would cover your jack. I would try contacting where you bought the trailer.

  • Troubleshooting a Stromberg Carlson Trailer Jack # JET-3500 that Was Stuck with Blown Fuse
    What is probably occurring on your jack is that it has been extended too far at some point and has become stuck. Trying to move it in either direction draws too much power as the motor tries to push the leg free. This cause the fuse to blow. What many electric jack manufacturers will do is to smash or otherwise distort the end of the screw that turns to move the leg up and down to prevent it from extending to far. If it does end up extending too far the threads will become permanently...

  • Troubleshooting a Jammed Electric Trailer Jack
    It is likely that the interior gears have stripped due to the jack over-extending. Since manually cranking the jack is unsuccessful, you will probably need to replace the jack, as the jack manufacturers will smash or otherwise distort the end of the screw that turns to move the leg up and down to prevent it from over-extending. If it does end up extending too far the threads will become permanently cross-threaded and it will never work right again.

  • How Does the Stromberg-Carlson Electric Jack Wire for Installation
    Typically these powered jacks would get their power from a trailer mounted battery that is maintained via the 7-Way on the truck. The truck would keep the battery topped off when towing down the road and the jack would pull the amperage it needs from the trailer battery. So yes, you would attach this Electric A-Frame Tongue Jack # JET-3555 to the positive side of the battery for installation.

    You should be able to manually crank the Electric A-Frame Tongue Jack, # JET-3555, up and down by removing the rubber plug on the side and inserting the manual handle or a properly sized socket wrench. Turn clockwise to extend the jack and counter-clockwise to retract it. I spoke with one of our installers about the fuses blowing. He stated that the power wire could be shorting to ground or there could be an internal component that is shorting out. Make sure all ground connections are...

  • Troubleshooting Strornberg Carlson Powered Jack Not Working with Parallel Trailer Batteries
    The issue you are having is most likely ground related, but what you can do is run a wire from the mounting bracket of the # JET-3555 to the main negative post of your two batteries ran in parallel. As long as your battery ends up delivering 12 volts to the trailer accessories the jack would work just fine. Because of that the issue is has to be a ground. You might check the condition of the fuse in the yellow fuse holder as well.

    If you are able to operate the lights on your electric trailer jack, like the Stromberg Carlson # JET-3555, but not the jack itself then you either have a battery that isn't fully charged or the jack itself doesn't have a good ground. The lights on a jack don't draw much power but the operation of the jack does.

  • Electric Trailer Jack Will Not Work Even with a New Battery
    The first thing I would check is where the electric jack # JET-3555 is mounted because that is also where it grounds to the trailer. Make sure there is no corrosion between the jack and the surface it mounts to. With that cleaned up, the new battery, and the in line fuse still intact the jack should work. If it does not then it is likely a shorted switch. You would have to take the cover off of the jack to access the switch wiring or the wiring directly to the motor. That way you can...

  • Troubleshooting Electric Trailer Jack that Doesnt work When Not Connected to a Tow Vehicle
    The problem is most likely the ground circuit for the jack.

  • Troubleshooting JET-3500 Jack that Wont Extend/Retract But Light Still Works
    Since the jack grounds through the mounting assembly the first thing I would do is check the condition of the main ground of the trailer and for corrosion near the mounting assembly and clean as necessary. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. An inadequate ground would allow the light to still work but could prevent it...

  • Lubrication Required for Stromberg Carlson JET-3500 Powered A-Frame Trailer Jack
    According to my contact, the gears of their # JET-3555 are lubricated at the time of manufacture and no further lubrication of the internal gears is necessary. The only part recommended for lubrication is the inner jack tube. I've linked you to a product demonstration video featuring the # JET-3555 powered trailer jack.

  • Replacement A-Frame Jack Recommendation for a 2011 Keystone Passport Ultra Lite
    The Electric A-Frame Tongue Jack # JET-3555 that you referenced was designed to fit basically all a-frame trailers. Since yours had an a-frame powered jack on it already this would work well as a replacement for it. This jack has a 3,500 lb lifting capacity which would be more than enough. Check out the review video I attached as well. For a black version similar to this you would want the part # JET-3755.
