Electric Motor Conversion for 2 Speed Gooseneck Jack
This electric motor retrofit kit fits heavy duty two speed sidewind trailer jacks with a 1" shaft diameter.
Designed to be mounted on the 1-1/2" input shaft hub of gooseneck horse/stock trailers and fifth wheel or gooseneck race/cargo trailer jacks.
Operates from trailer's existing 12Volt DC power source.
Comes complete with two way (forward - reverse) toggle switch, jack shaft coupler, pins, emergency crank handle kit with extensions and installation instructions.
Motor is a single speed unit designed to be used on LOW speed side of gear box only.
Please see "Size" image above to determine if your trailer has enough clearance for this motor/gearbox assembly.
Designed for Binkley / Holland LG4700 series gooseneck jacks, but will work on jacks similar to the one pictured above having a 1-1/2" diameter by 1-1/4" long support hub for input (crank) shaft and a 34 turns per inch of travel rate in low gear.
Jacks manufactured after September 2010 no longer have the support hub welded to the gear box. If the hub is not present on your jack you will need to add the 1-1/2" Support Hub Bracket kit shown as an option just above the Add To Cart button.
Input shaft must measure 4-7/8" from gearbox face to center line of bolt hole when in low gear.
If any of the dimensions on your jack are different please contact us by phone or email.

Jack shown for illustration purpose ONLY, available for purchase separately.
**Can vary depending on condition of jack, trailer geometry, parking position etc.
