  • Recommended Electric Trailer Jack For A 2018 Jayco Whitehawk
    Hi Tom, I have two options to replace the electric tongue jack on your Jayco Whitehawk: Option 1: Electric Jack w/ Footplate # EJ-3520-BBX. This jack is going to be your no-frills 'get the job done' style jack. It has a 3,500lb capacity and what it lacks in looks it makes up for in dependability. The simple design of this jack also allows for easier replacement of damaged or worn components unlike a lot of other jacks that require complete replacement when something malfunctions. Option...

  • 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 Trailer Jack and Winch Recommendations for an Enclosed Car Hauler Trailer
    Thanks for reaching out and on your new trailer, Eric! The Lippert Smart Jack # LC643589 is great in theory, but they've had issues with water leaking into the head, and I haven't recommended one since I found out that they don't cover that under warranty and their solution is to replace the jack entirely. For a high-performance jack it's hard not to nod at the Ultra-Fab Phoenix # UF38-944040 because it's the fastest operating jack that we carry, and it uses a ball screw which is a very...

  • Troubleshooting Phoenix 4000 Electric Jack Not Working
    Phoenix Electric Trailer Jack - A-Frame - 22-1/2" Lift - 4,000 lbs # UF38-944040 sounds like it needs a better ground connection. You can wire it directly to the battery like in the installed video or you can install the ground wired to the trailer frame directly with a bare metal to metal connection. The battery itself may need a charge so I'd check that out as well by connecting to a different battery or charging the trailer battery then reconnecting the jack. If the red LED flashes...

  • Troubleshooting Phoenix Electric Trailer Jack UF38-944040 Beeps And Will Not Go Down
    Hello Clint, thanks for getting in touch. With the Phoenix Electric Trailer Jack # UF38-944040, generally when the unit beeps and does not function properly, it is due to a low voltage situation. The first thing to do will be to check your battery and make sure it is fully charged and in good working order. Also make sure the jack is properly grounded. Check the jack wiring for any damaged or frayed wire that may be causing a short. If this does not resolve the problem we could be looking...

  • Will Lippert Smart Jack and Phoenix Electric Trailer Jack Fit 2019 Lance Model 1985 Trailer
    Hey Joe! Did your old jack quit on you? Your 2019 Lance 1985 travel trailer will have the standard A-frame 3" bolt pattern on the tongue. Both the Lippert Smart Jack Electric Trailer Jack # LC643589 and Phoenix Electric Trailer Jack # UF38-944040 will fit. The one big advantage the Phoenix has is the warranty. The standard warranty is a 2-year but if you register the jack within 90 days you will get a 10-year warranty which is really nice to have.

  • Troubleshooting Ultra-Fab Electric Jack Has no Power When Lifting Trailer
    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. It is probably getting power, it just may not be enough to lift the trailer. I would start by checking the wire running to the jack using a circuit tester like # PTW2993. You could also double check the trailer batteries. If you find it has 12V power and still isn't working it may be that the motor is giving out. It would...

  • Is There a Electric Trailer Jack that is Actually Fast
    Hey Raymond, since the 5k rated etrailer jack part # e55ZV is rated higher than the 3.5k option you also mentioned it will work a little bit quicker since it won't be working quite as hard. With that said it's not a fast jack by any means. It would still require a decent amount of time as that's the nature of these types of jacks. Now if you really want something that moves quickly we have the Phoenix jack part # UF38-944040. This will extend 6 inches with a heavy load on it in 9.5 seconds...

  • Recommended Nice A-Frame Jack For Heavy Car Hauler
    Hi Aaron; so there isn't anything that can be used with a cordless impact gun, that's just not something that is attainable. But for a strong, fast, heavy-duty A-frame jack that can handle the weight you need? 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. It also extends 6 inches in just under 10 seconds which I know...

    The Ultra-Fab Phoenix Electric Trailer Jack with Remote- 5,500 lbs # UF38-944055 or 4,000 lb # UF38-944040 without remote sounds like it may have a mechanical issue. I recommend using the manual crank to extend or lower the jack. If you can use this, then you isolate the issue to electrical with a possible bad ground or motor issue. If you can't physically move the jack with the manual crank then we know the issue is mechanical with the inner rod seized or having stripped threads. If...

  • Mounting Flange Diameter of Phoenix Electric Trailer Jack
    Hey Byron, thanks for writing in, and the mounting flange is 5.3" (or 5-5/16") on the Phoenix Electric Trailer Jack # UF38-944040. You made an awesome choice here with the Phoenix as it's as good as it gets for an A-frame jack. The thing cooks in regards to travel (at least relative to trailer jacks), extending 6" in 9-1/2 seconds. I also thought you might want the rest of the dimensions so I went ahead and got ahold of the manufacturer to get all the dimensions of the Phoenix # UF38-944040.

  • Powered Trailer Jack Recommendation for Trailer with 400 lb Tongue Weight
    Hey Ed, so the electric trailer jacks are all going to have way more capacity than needed for your 400 lbs of tongue weight so I would pick a trailer jack based on different criteria. Instead I would go with the Phoenix part # UF38-944040 as it can raise and lower in a matter of seconds instead of having to wait around like most of the other jacks that are quite a bit slower. We have an option that also has a remote to control it with the part # UF38-944055 but it does cost more. If...

  • Electric Tongue Jack Upgrade Recommendation for a Safari Condo Alto F2114
    Thanks for reaching out, Ger! For a simple replacement A-Frame jack I recommend checking out the Electric Jack w/ Footplate and 7-Way Plug # EJ-3527-BBX which is essentially your industry-standard quality jack with a 7-Way plug that you'll connect to your vehicle to operate the jack. If you want something that operates a bit quicker then I recommend the Phoenix Electric Trailer Jack # UF38-944040 instead because it lifted 1,000 lbs in a quarter of the time (10 seconds) that it took the...

    Hey Brian, thanks for reaching out! Are you looking for best brakes that match your current setup (drum brakes) or like the best brakes on the market? If you're wanting the best brakes on the market, then you'll need the following: - DeeMaxx Disc Brake Kit - Maxx Coat/Stainless # DE46YR - DeeMaxx Hydraulic Brake Line Kit # DE24SR - DeeMaxx Alpha G1600 Electric Over Hydraulic Actuator Kit # DE75KR This changes your setup to disc brakes that are still operated by your electric brake...

  • Recommended Quickest Electric Jack for a Travel Trailer
    I hear you Steve. A bunch of these jacks are frustratingly slow. The quickest one we have is the Phoenix Electric Trailer Jack item # UF38-944040. With a 1,000 lbs tongue weight, this jack extends 6" in 10 seconds and retracts 6" in 8.6 seconds. It looks like your Grand Design 22MLE maxes out around 7,000 lbs when loaded, so you should expect a similar response time. What kind of jack do you currently have? You can add this information and any other questions you have where it says...

  • Best Solution For Gaining Tail Gate Clearance On A-Frame Trailer Tongue Jack
    Since the Ultra-Fab Electric A-Frame Jack # UF97FR has a triangular bolt pattern it would rotate the jack 120 degrees and may or may not work for your application. There are other jacks which have multiple mounting patterns on the flange like the Phoenix # UF38-944040 which will allow for 90 degree placement on the jack. A much simpler option I find is to use an extended Ball Mount # BH20 or a extended Drop Shank # EQ90-02-4600 if you have a weight distribution hitch. This means no mater...

  • 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,...

  • What Capacity Electric A-Frame Jack for 7,000 lb Trailer
    An electric A-frame trailer jack only needs to support the tongue weight of your trailer, which is approximately 10% to 15% of your trailer's GVWR. Almost all A-frame jacks nowadays are rated for way more than they'll ever be required to move, so you have a ton of choices for a 7,000 lb trailer, and I'll go over the best options for you. - The Best: Phoenix Electric Trailer Jack - A-Frame - 22-1/2" Lift - 4,000 lbs # UF38-944040 This baby is all about speed, travelling 10 inches in just...

    Trailer jacks do sometimes fail even when they are being used under their capacity so while it's a bummer that yours did I wouldn't say you did anything wrong and maybe just had some bad luck with yours. For a replacement I really like the Phoenix Electric Trailer Jack part # UF38-944040 which has a slightly higher capacity at 4k but what I really like about it is that it is incredibly fast. It can fully extend or retract in less than 10 seconds. It also has a reputation as being very...

  • What is the Most Reliable Electric Trailer Jack for Lance Camper
    I can't tell you what the most reliable trailer jack is as we don't really have testing to support this but what I can tell you is that the Phoenix Electric Trailer Jack part # UF38-944040 has a longer warranty than any other jack on the market, 10 years. I got to use this jack a bit and was very impressed, mostly due to its speed which you can see in the video below.

  • Troubleshooting A Non-Working Ultra-Fab Phoenix Electric Trailer Jack
    If your Phoenix Electric Trailer Jack # UF38-944040 has power but isn't extending/retracting and the light isn't working then your in-line fuse has most likely blown. If you look at the attached video below around 9:30 minute mark Conner will show you the included fuse holder. You'll want to unscrew the cap on the fuse holder and check that the wire inside the fuse isn't blown apart. You can pick up replacement 30 amp slow blow fuses at your local hardware store.

    The electric jack I strongly recommend for your 2019 Forest River Micro Lite 21FBRS is the Phoenix Electric Trailer Jack # UF38-944040 because of its unparalleled performance in regards to speed. This jack will give you 10" of travel in just 18 seconds, making it the sports car equivalent of electric trailer jacks; it has 22-1/2" of total travel and a 4,000 lb lift capacity, which is more than enough for your Forest River.

    It sounds like your 3,500 lb Electric Jack w/ Footplate # EJ-3520-BBX has a bad internal screw. Since you've tried to operate it both electronically with the buttons as well as mechanically with the manual override you've been able to rule everything else out (good job!). Unfortunately it doesn't look like this is a replaceable part so you'll have to replace the jack entirely and for that I recommend either part # EJ-3520-BBX for an exact replacement or the Ultra-Fab Phoenix # UF38-944040...
