Never Crank That Trailer Jack Again, Convert your manual two speed jack to electric.
The Magnum Lift Systems 2SPDMTR electric gooseneck trailer Jack converter is an easy upgrade, designed to convert your gooseneck trailer two-speed manual jack into a power jack capable of lifting up to 6,500 pounds of jack weight at 7 inches per minute.
It comes standard with a 5/6” socket manual crank backup shaft in case of battery failure. This conversion will work with single or dual landing gear jack (one converter will raise a single jack or dual jacks), and can mount on either side of the jack leg.
The Magnum Electric converter is 9-1/2” wide and installs with basic hand tools. 2 Year complete factory warranty. Made in the USA, Ellington, Missouri by Magnum Lift Systems.
The 2SPDMTR for a 2 speed gooseneck trailer jack converter will not work on a single speed jack. Or on a Ram 2 speed jack. The Ram 2 speed jack has a higher speed gear ratio than the Bulldog jack, Holland jack or Binkley jack. The Ram jack is not a first line quality jack but is a very low cost China jack.
