Lift your gooseneck horse or motorsports trailer with the EQ Systems AJ 2/24 Dual-Leg Hydraulic Jack System — a complete dual-leg hydraulic lifting system that bolts to the front of a gooseneck trailer, featuring 3.5" × 3.5" tube-in-tube AJ-series jacks, 24" stroke, and 16,000 lbs total lifting capacity. A single rocker switch runs both legs in tandem for simple, straightforward operation. Available at The RV Surplus.

⭐ 16,000 lbs Dual-Leg Lift

• Two AJ-series 3.5" × 3.5" tube-in-tube legs
• 24" stroke each
• Single rocker switch runs both legs in tandem — simpler control than independent switch versions

⭐ Weatherproof Keyed Control

• Weatherproof switchgear with rocker switch and key standard
• Prevents unauthorized use

⭐ Screw-Drive Manual Override

• If power fails, drive the pump with a reversible drill through the override shaft
• Use a 6mm (1/4") Allen hex key
• Clockwise retracts, counter-clockwise extends
• Drill must reach at least 2000 RPM for adequate pressure
• Take care not to contact wires or hoses with the drill

What's Included (8414AMUPS)

• Two AJ-series 24" stroke jacks
• Commercial single-function pump with screw-drive manual override
• Steel pump cover
• Weatherproof keyed switchgear (single switch, tandem operation)
• Universal mounting brackets
• Wire harnesses in PVC high-temperature nylon braid

Battery Requirements

Load-test the battery before installing. EQ Systems requires a minimum of 150 amperes at 10.5 VDC for at least 30 seconds.

Fluid and Maintenance

Runs on Dexron III ATF, filled to about 1" below top of reservoir with jacks fully retracted (level rises as jacks retract). Reservoir must run with its vented breather cap fitted, not the flush shipping plug, or the jack will operate erratically. Inspect every 12 months.
