Two Speed Gooseneck Trailer Jack Magnum Lift Conversion Kit
Some gooseneck horse trailers and race car haulers come equipped with 2 speed gearbox style heavy duty trailer jacks. The Magnum Lift LEGB-2 12 volt electric conversion kit fits and works with several manufacturers' gooseneck landing gear.
This kit mounts on the 1-1/2" diameter support collar installed on Binkley / Holland jacks produced prior to September 2010, as well as most other jacks having the support hub.
If your two speed jack does not have the hub, like the later model Holland / Binkley units, we have an adapter hub kit available for purchase which can bolt or weld to your jack gearbox.
This kit comes complete with the high quality Magnum Lift wire harness, in line circuit breaker and switch box with high ampere capacity switch for up and down operation. All of these components are pr-wired to make the electrical hook up to your trailer battery a snap.
If you have space or clearance issues the kit can usually be mounted to the left side of the jack by welding the mounting bracket. The lower "crank" shaft needs to extend approximately 3" past the left side of the jack body in order to allow this type installation.
This conversion kit is NOT intended for use on semi trailers.
