Features to know about

Smooth, Easy Lifting: Topwind Handle with 15" Lift

Cranking doesn’t have to feel like a workout. The Round A-Frame Trailer Jack from etrailer gives you 15" of lift and a topwind handle that turns easily, even under load. The black claw knob has a comfortable grip, and the zinc-finished arm resists rust while looking clean. Whether you’re hitching up or parking for storage, the internal gearbox keeps movement controlled and consistent every time.

Built to Last: Heavy-Gauge Steel with Black Powder Coat

This jack is made to handle real use and rough weather. The heavy-gauge steel construction is finished in a protective black powder coat that holds up against rain, salt, and road grime. A zinc-finished handle arm adds extra corrosion resistance, so it keeps turning smoothly long after cheaper jacks start to seize up. Users say it’s noticeably more heavy-duty than the originals it replaced and still works like new after a year of use.

Simple Fit and Replacement: Standard 2-1/4" Outer Tube

Swapping out a worn or stripped jack shouldn’t mean drilling new holes. With a 2-1/4" outer tube and standard A-frame mount, this jack fits most common coupler openings and can replace many older models directly. If your previous jack had a 2" diameter, the 2-1/4" size still fits most mount holes without modification. Bolt it on or weld it in place, and you’re ready to go.

Compact and Easy to Store: Folding Handle Design

Space is always at a premium when you’re loading or backing into a garage. The 8" handle radius gives you plenty of leverage without sticking out too far, and when you’re done, the handle folds away neatly against the tube. The result is a clean, compact setup that’s out of the way but always ready when you need it.

Dependable Strength: 3,000-lb Lift, 5,000-lb Support

This jack is built for serious tongue weight. With a 3,000-lb lift capacity and 5,000-lb support rating, it’s strong enough for heavy utility and enclosed trailers. Combine it with a footplate or caster (sold separately) for added stability, and you’ve got a setup that keeps your trailer secure and level through every hookup, tow, and storage day.

Great Customer Service, Fast Shipment and the tongue jack fit perfectly.
by:
Excellent, does what it should just wish my tailgate cleared it. (not the fault of the product just the buyer)
by:
the order was fast and was just what i ordered thank you
by:
Just installed this jack after the original jack on my trailer collapsed, stripping the threads on the way down. The Ram jack fits like a glove using my original three bolts. My first impressions are that it’s well-built and much smoother than my OEM jack. I paired it with etrailer’s drop foot, and I think I’m set for easier coupling moving forward.
by:
Trailer jack still good as new a year later. The one that came on my trailer originally lasted just over a year before I could barely crank on it and it squealed horribly. But this one is working as good as it did the first day a year later so 5 stars all the way
by:
Nice Jack! Works well with JF-1005H-Z Drop Leg for etrailer and Ram Jacks. The PS1400600303 Pro Series Round, A-Frame Jack - Topwind - 15" Lift - 5,000 lbs does not work with the drop leg. Had to learn the hard way.
by:
Good quality jack. Easy to install, works great! Fast shipping and great communication from etrailer.com as always.

Can I get these without etrailer name and phone # on the jack

These are etrailer branded but made by RAM. They are pre-stickered before they arrive to our warehouse.

by:
Easy to install. Much easier to lift the trailer with, makes it almost effortless. Don't forget to order the jack foot that you wish to use.
by:
Needed a replacement tongue jack, asked their tech staff to review my specs for compatibility and they suggested a this better (and cheaper!) alternative within 24hours. This is much heavier duty (and cheaper) than the one I'm replacing. It is built to last. Def my go-to for trailer parts.
by:
Switched from a side crank to this top crank trailer jack. Made of heavy gauge material, turns smoothly under pressure. I would recommend this jack.
by:
Exact fit for my old attwood that I couldn't find replacement parts for.
by:
More heavy duty than the original, fits perfect, and has been working great!
by:
They upgraded the shipping. Jack fit and worked perfectly.
by:
Just what I needed, I will be back for more.
by:
I had to enlarge the lower "support hole" that it had to go through, but otherwise it went in easy. Made in China. Works good though.
by:
Bolted in place since I know I will forget it and need to replace it sooner or later.
by:
Showed up on time. Installed it and it works great.
by:
Still holding trailer up

These guys are great. Good service, Knowledge, etc. Delivery is exceptional.
I will definitely use them again.

Working good so far

  • Do you Have a A-Frame Jack for my 7,000 Pound Trailer with an Adjustment Greater than 23"?
    Hello Greg, I’m assuming the overall weight of your trailer is 7,000 pounds. In that case, you’ll just need something to handle the tongue weight of the trailer. Tongue weight typically falls between 10–15% of your overall trailer weight, which would put you between 700–1,050 lbs. We don’t have anything in a round tube that has a 23" lift, so I’m hoping you’re referring to the overall extended height. The Round A-Frame Trailer Jack - Topwind - 3,000 lbs # TJA-5000T-B has a 15" lift,...

  • What Washers Should I Use Under the Mounting Nuts for the Round A-Frame Trailer Jack?
    Hello Rick, Thanks for finally finding a reason to write into us, I see you have been a faithful etrailer neighbor (customer) since 2014! For the Round A-Frame Trailer Jack - Topwind - 15" Travel - 3,000 lbs # TJA-5000T-B, you'll want to use a flat washer under the bolt head and another flat washer under the nut. A lock washer should be installed between the flat washer and the nut to help prevent the hardware from loosening over time. So, from the bottom up, the hardware stack should...

  • Recommended Replacement for Shelby 5759 Trailer Jack
    I do have options for you but we don't offer any direct or even like replacement options for the Shelby 5759 Jack. This was an odd design and the manufacturer (Shelby) has been out of business for quite some time. That said, so long as you are willing to replace the coupler as well which it sounds like you are then we should be able to get you back up and running in no time. I recommend the Demco A-Frame Trailer Coupler part # DM14793-81 to replace the coupler and then the Round A-Frame...

  • Do You Carry a Bolt On Trailer Jack Which Mounts to a Trailer Tongue With 2 Mounting Bolts Versus 3?
    All the bolt on trailer jacks we carry use the 3 bolt pattern which is commonly found on todays Couplers # DM14793-81. You may be able to replace your current jack with a Round A-Frame Trailer Jack # TJA-5000T-B. This will require a 2-1/4" hole opening for the jack to fit through as well as new mounting holes to be drilled into the mounting plate to secure the jack.

  • Solution for Replacing Trailer Jack with 2 inch Outer Diameter
    The most common outer diameter for an a-frame trailer jack is 2-1/4 inch but the 2 inch diameter you have is also reasonably common as well. In nearly all situations a 2-1/4 inch jack will replace a 2 inch jack as the hole on the trailer frame where the jack passes through is big enough for both sizes. If you do find that you need the 2 inch diameter we have the Dutton Lainson part # DL22530 which is this size. Otherwise if you can get away with 2-1/4 inch the part # TJA-5000T-B would...

  • Do Topwind A-Frame Jacks Use The Same Gears As Sidewind Jacks
    Replacement gears are brand and model specific so I would need to know exactly what you have in order to find the correct replacements. Topwind jacks, like the Round A-Frame Trailer Jack # TJA-5000T-B will typically have a threaded rod that the handle attaches to and usually a use a bearing instead of gears like a sidewind jack does. If you can provide me with some picture and any other information you have on the jack I'd be happy to look for replacement parts for you.

  • Recommended Replacement A-Frame Jack For A 2021 Aliner Ranger 12
    The Pro Series Round, A-Frame Jack # PSRV20000103 will definitely definitely fit in frame as the 3" triangular bolt pattern is a standard, but I cannot 100% say that your existing wheel will fit. It most likely will, but I do have an option that I can 100% say will work. The etrailer.com Round A-Frame Trailer Jack # TJA-5000T-B is a RAM jack, though this will be a little more heavy duty than your original one. It will have a 5,000 pound support capacity, a 3,000 pound lifting limit, and...

  • How Long is the TJPB-HD Replacement Handle?
    The Replacement Topwind Black Knob Handle for Ram Jacks # TJPB-HD will measure right at 8 inches from the center of the clamp to the furthest most edge of the handle/knob. This will also fit all Ram TJB, TJP, and TJDP Series jacks as well as our Round A-Frame Trailer Jack - Topwind - 15" Travel - 5,000 lbs # TJA-5000T-B.
