AM 1/24 with Manual Override Screw Drive
$1,370.00
AM hydraulic trailer jack, single leg, 24" stroke
Complete single leg hydraulic lifting system for a gooseneck or fifth wheel trailer. The AM series is the 4" x 4" square tube in tube jack, and this system lifts 12,000 lbs. Push button lifting replaces cranking a manual jack, which on a loaded horse or motorsports trailer is the difference between a two minute hook up and a fight.

Manual override: screw drive
If the system loses power, the jack is driven by hand through the output shaft on the end of the motor. Remove the pump top cover, then the silver sticker on the end of the motor, and drive the override coupler with a drill capable of at least 2000 rpm, using a 1/4 inch (6mm) Allen drive hex key. Take care that the drill does not contact wires or hoses. The drill has to reach 2000 rpm or the pump will not develop enough pressure to move the jack.
Standard and optional equipment
- Keyed switch and harness standard, which also prevents unauthorized use of the system
- Wireless remote option, part 7823 for single function jacks
- Universal mounting brackets included
- Switchgear built in house, performance verification tested, braided nylon exterior
Battery requirement
EQ Systems recommends a minimum group 24 RV or marine battery rated at least 100 minutes reserve capacity and 500 cold cranking amps; the higher those numbers the better. Flooded lead acid, gel and AGM types are all suitable. Some lithium batteries cannot deliver the running amperage this system needs, so check with the battery manufacturer before fitting one. If the trailer sits between trips, Stay Charge parts 8400 and 8427 charge the trailer battery from the tow vehicle, and solar kit 70486 keeps the jack battery topped up.
Fluid and maintenance
An AM single leg system runs on Dexron III ATF, filled to about one inch below the top of the reservoir with the jacks fully retracted. Remember the level rises as the jacks retract. The reservoir must run with its vented breather cap fitted, not the flush shipping plug, or the jack will operate erratically. EQ Systems recommends owners inspect the system every 12 months, checking that all connections are tight and free from corrosion, particularly the ground to the pump stud and the positive cable to the motor solenoid.
Service parts
The replacement hydraulic cylinder for this jack is part 1179EQ. Cylinders are identified by the jack outer tube size and length, not by the bracket. The switchgear for this single function system is 6526.
