Gearboxes are designed to fit on standard heavy duty trailer jacks with a 1" round handle shaft. Sometimes refered to as trailer landing gear or trailer legs, these usually have an S shaped handle pipe handle attached to them. Some applications may have a hex shape or cross pin interface on the handle. Most of these jacks are 4 inches square and welded to the trailer, though in heavy trailers they may be even larger. We offer a selection of ACCESSORIES to adapt to your setup. Our Trailer Gearboxes replace the manual cranking of your handle with a gearbox that uses gear reduction to allow you to rasie and lower your trailer with a cordless drill.

Jacks are designed to replace the bolt on jacks that are commonly seen on car trailers, boat trailers, small-medium size equipment trailers and enclosed trailers. There are many different mounting styles such as A-Frame, clamp-on and swivel mounts. Our drill powered jacks replace the manual cranking of your handle with a gear reduction system that allows you to raise and lower your trailer with a cordless drill.
