This thing is amazing! I originally bought the socket attachment for my 26ft equipment trailer but it was way too much for the flagship Milwaukee drill. I’m so happy I found this geared mechanism. It makes hitching and unhitching my big trailer so easy!

Amazed 👏
I have a 30 ft goose neck flatbed trailer that from the time I bought it, it was hard to jack up or down so always hated hooking it up. Bought the Gearbox with this trailer in mind, skeptical that it may not work that well, but was amazed at how easy the Gearbox and a little drill could lift and lower the jack! Totally Impressed!!

I need to update my situation. I just got a call from Trailer Gearbox. It turns out i put the wrong address, and it was delivered 1 block away from my house. I am trying to find it, but they are sending another. Wow, that is amazing service that you don’t see anymore these days. Very impressive. Thank You Trailer Gearbox Team.
