Dexter Trailer Jack
- DX42CR
Highlights
- 20,000-lb Combined Hydraulic Lift: Two 10,000-lb jacks raise heavy equipment, livestock, and commercial trailers together.
- One HPU Powers Both Jacks: Included double-acting power unit handles extension and retraction for the complete tandem setup.
- Flow Divider Included: Splits hydraulic flow between both legs so they can raise and lower together from one control.
- 20" of Powered Lift: Each jack gives you plenty of range for hitching, unhitching, and adjusting trailer height.
- Direct-Weld Installation: Matching 4" square jack tubes weld permanently into suitable locations on the trailer frame.
- Complete Hydraulic Plumbing: Six 48" hoses and the required fittings are included to connect the tandem system.
Features to know about
Raise a Heavy Trailer from Two Points: Tandem Hydraulic Jacks Share the Load
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.
Power Both Legs from One System: Separate HPU and Flow Divider Work Together
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.
Plan the Installation Before Welding: Keep Each Foot Within 8" of the Frame
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.
Everything Connects as One System: Hoses, Fittings, and Battery Cables Are Included
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.
Give Both Legs a Solid Base: Wide Feet Pivot with the Ground
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.
