My son and I have used several times and have been happy with the every time. Normally items arrive quicker than expected. We will definitely keep using them for anything we need.


Working perfectly out of the box. Time will tell


The Jack was to big around but good had to grind the hole on my tent trailer a little bigger to get it to fit in the hole other than that it works good


Excellent jack at an excellent price, bent my old one and this was an exact bolt-in replacement for my Bri-Mar dump trailer


Love it! It works smooth even with weight on my trailer


I was very happy as to the speed as to how it came, Very Fast, Thank You.


Quality product. I have made several purchases from etrailer and they are the "number one go to" source for anything related to trailers.


It’s a beautiful thing!


I always get great service form etrailer. I do not order a lot maybe something every year or two, but the experience to always excellent.

Exceeding expectations! Works better than the original one that was on there! I will definitely be ordering more parts from there...


Excellent product and customer service. Thank you.

  • What Size Bolts to Install etrailer Jack TJA-5000-B
    You can use three 3/8 inch bolts to secure the etrailer electric jack # TJA-5000-B to the trailer. The length of the bolts will depend on what is required by the trailer. I have included a link to a video review of this jack for you.

  • Does Grease Needed To Be Checked/Added In The Round A-Frame Trailer Jack TJA-5000-B?
    The Round A-Frame Trailer Jack # TJA-5000-B you were looking at does not have grease zerks, nor is it greaseable. This is the same for all of the top wind A-Frame jacks we offer. The reason for this is A-Frame jacks like this are sealed to keep debris and moisture out so grease does not need to be added. In addition the amount of revolutions the jack makes is nothing compared to components that need the grease changed such as a hub assembly on the trailer, so the grease does not really...

  • Does etrailer Drop Leg Fit 5,000 Pound Sidewind Jack
    The drop leg # JF-1005H-Z fits 2,000 pound etrailer and Ram jacks as well as topwind 5,000 pound jacks, like part # TJA-5000-B but it doesn't fit the 5,000 pound sidewind jacks like # TJA-5000S-B. The inner tube on the 5k sidewind jacks have a thicker inner tube that doesn't allow the leg to slide up inside.

  • Recommendation for Economic A-Frame Trailer Jack with 3 Hole Mounting Plate
    For your trailer, I recommend the Round A-Frame Trailer Jack # TJA-5000-B. This economically priced A-Frame jack features a lift capacity of 3,000 pounds and a static capacity of 5,000 pounds. You will just want to make sure this is sufficient for the tongue weight of your trailer. It will give you a total travel of 14-1/8 inches. It does have a 3 hole mounting bracket and an outer tube diameter of 2-1/4 inches. I have attached a short video demonstration on this product...

  • What is the Lift Capacity of the Square A-Frame Jack # TJDA-5000S
    The lifting capacity of this jack is determined by the drop leg. In this case the Drop Leg # TJD-5000-FT that comes on the # TJDA-5000S jack is rated for a 3,000 lb lift capacity. If you are needing a trailer jack that has a 5,000 lb lift capacity then I recommend the Round A-Frame Trailer Jack # TJA-5000-B. There is a drop leg that you can purchase for this jack as well. The Drop Leg # JF-1005H-Z will give you a little more surface area for your trailer jack to use.

  • Jack With Short Retracted Height for Horse Trailer
    The # TJA-5000-B jack has a 10-3/8" retracted height without a footplate so for a 5,000 lb jack with less retracted height, a great option is the Rack'em B-52 Round A-Frame Trailer Jack # RA-29. This jack has just an 8-1/2" retracted height and if you add the Bulldog Detachable Footplate # BD018564 you will be adding less than half an inch to that. If you needed even less height you would need to get a jack that does not have as much lift capacity. The lift capacity only needs to support...

  • Bolt-On Swivel Trailer Jack for Side-Mounting on Trailer Frame
    If tailgate clearance at your trailer's a-frame tongue jack is a concern you might want to switch to the Bulldog Topwind A-Frame Jack # BD155032. This 5K jack requires only 10-3/16-inches of clearance above the mounting bracket (not including the handle) so it should fit at your tailgate. Bulldog is part of Cequent Performance Products, parent company of brands like Reese, Tekonsha, Draw-Tite, Fulton and others. This is a high-quality jack that will have replacement parts available into...
