Upgrade a bumper-pull trailer from manual cranking with an 8K hydraulic tongue jack. The dedicated 12V pump, local toggle control, standard tongue-jack mounting design, and 16-1/2" of lift give you a straightforward powered setup.
Horse, livestock, cargo, and equipment trailers can put enough weight on the tongue to make a manual jack a chore every time you hitch or unhitch. This Bigfoot jack gives you 8,000 lbs of hydraulic lifting capacity and 16-1/2" of lift, letting the powered system handle the work instead.
The jack measures 8" retracted and 24-1/2" extended, giving you a compact starting height with enough movement to raise or lower the tongue for hitching. Its 1-1/2" hydraulic shaft is built around the demands of heavier bumper-pull trailers.
This is a self-contained setup with its own 12V hydraulic pump and reservoir mounted with the jack. A rubber-booted toggle switch at the pump assembly controls extension and retraction, so there is no separate hydraulic system or remote control to add.
The kit includes hydraulic hoses and fittings, battery cable, mounting components, and the hardware shown with the system. You supply a 12V battery and 2 quarts of Dexron III ATF. The hydraulic system calls for at least 4-gauge battery cable.
This configuration does not include a built-in manual override. If the trailer loses 12V power, there is no separate manual backup included with the system, so keeping the battery and electrical connection in good condition matters.
The round jack is designed for a standard bumper-pull trailer tongue-jack opening, making it a practical hydraulic replacement for many A-frame tongue jacks without requiring a welded side-mount setup.
The mounting plate and installation hardware are included, but standard opening does not guarantee that every trailer uses the exact same bolt pattern. Compare your existing opening and mounting holes before installation so you know what will line up and where additional drilling may be needed.
