Trailer Jack Mod?

Anybody ever modify their trailer jack so it can be raised and lowered with an electric impact wrench. Thinking of removing the top wind handle and fitting a coupling nut on the top of the jack. I saw this mod on another forum and it seemed kind of slick. You can always use a ratchet wrench in case the impact battery dies. Thoughts?
  • make a socket from pvc pipe with a slot down one side.. for handle to fit... epoxy the inside to hold a flat bit wood drill bit..

    cut drill bit to length.. and use a battery powered drill. and same drill for stabilizer jacks with a 3/4 inch socket..

    do a search here of photo and directions on the crank handle socket...
    I did one 3 years ago.
    NO MOD needed for crank handle

    FYI.. Harbor Freight has a power jack for 129 and use a common 20 percent off coupon. jack is rated for 3,000 pounds. I have not used one.


    DO NOT use hammer drill or Impact wrench.. will destroy gears... smooth, even power.. or arm power.
  • Hmmm seems more like a solution looking for a problem where the correct answer seems to be GET AN ELECTRIC TONGUE JACK. Be careful of the save a dime and cost yourself a fortune with a healthy side portion of grief syndrome.

    I also like the idea of keeping the 7way plugged in when using the electric jack for power and I do the same when putting my slide out before hooking up to the pedestal, but I have to have the Van running or it can take A LOOOOONG TIME to get the slide in/out just on battery alone.

  • LoL it always amazes me how much work someone will go thru to keep from "working" so hard or to spend a buck to save a dime.
  • My enclosed trailer has a flip foot so I don't have to hand crank the jack as much.

    I would be interested in this mod simply because I have 2 other trailers that have no batteries that would run an electric jack. I'm not interested in adding a full size battery to a utility or horse trailer.

    Yes, each trailer has an existing battery for the breakaway switch, but I wouldn't want to run an electric jack with it.


    no need for an external battery. simply tap into the constant hot on your 7 pin trailer harness that connects to the tow vehicle. As long as the trailer harness is long enough for you to be able to pull up a few inches without disconnecting it, it works off the tow vehicle battery. This is what i did on my 8 x 24 v-nose enclosed car hauler and it worked perfectly.


    Hmmm... I'll look into that. I bent my jack my toy hauler (not enough to really affect it, but enough to make it annoying) due to a newbie mistake and have been looking for an excuse to replace it. I could reuse the old one on the horse trailer. Thanks.
