Instead of cranking two heavy landing legs individually, this system uses a pair of hydraulic jacks to raise and lower the front of your trailer together. Each leg provides 10,000 lbs of lifting capacity and 12,000 lbs of support capacity, giving the system 20,000 lbs of combined lift and 24,000 lbs of combined support. Each jack also gives you 20" of lift for hitching, unhitching, and adjusting trailer height.
The included KTI DC-4442 12V double-acting hydraulic power unit supplies pressure for both extension and retraction, while the flow divider distributes hydraulic flow between the two jack legs so they can operate together. The 3-qt power unit provides up to 3,200 psi for extension and 1,500 psi for retraction, with a corded two-button pendant keeping operation in your hand beside the trailer.
The flow divider helps both legs operate from the same hydraulic system, but it does not make the jacks self-leveling. If one foot reaches the ground before the other, the system will not independently level the trailer from side to side.
Both 4" x 4" square jack tubes are designed for direct-weld installation. Position each jack so the distance from the bottom of its footplate to the underside of the trailer frame does not exceed 8", helping preserve the intended lifting geometry and usable range. The separate hydraulic power unit should be mounted in a weather-protected location on the trailer.
Six 48" hydraulic hoses and the required fittings are included to connect the power unit, flow divider, and both double-acting jack legs. Positive and negative 4 AWG battery cables are also included for a nearby 12V battery. If your installation places the battery farther from the HPU, use appropriately heavier cable to limit voltage drop under load.
Each jack uses a 9-1/2" x 9-1/2" pivoting footplate that spreads the trailer load across a broad contact area and follows uneven gravel, dirt, or pavement more naturally. The exterior-grade black finish helps protect the square-tube jack bodies through everyday weather and trailer use.

Overall the jacks and the system work good but the only thing that I would suggest it to make a cover that will fit over the hydraulic pump and motor! There are other manufacturers that have that option with theirs so there is no reason that this set up don’t have it
