EQ Systems AJ 2/24 Hydraulic Trailer Jack | Dual Leg | 16,000 lbs | 2-Function Manual Selector

Lift and level your gooseneck horse or motorsports trailer with the EQ Systems AJ 2/24 Dual-Leg Hydraulic Jack System with 2-Function Manual Selector Valve — the same 16,000 lbs dual-leg system as the tandem version, upgraded with a manual selector valve that gives you a twist knob for each leg to run them together OR independently for side-to-side leveling. Ideal for uneven parking sites. Available at The RV Surplus.

Fitment critical: Verify compatibility before ordering. Call EQ Systems at 800-846-9659.

⭐ Independent Leg Control — Level Side-to-Side

• Manual selector valve (part 1488T) adds a twist knob for each jack
• Open both knobs: jacks operate in tandem
• Close one knob: the other jack runs solo — legs operate independently
• Level the trailer side to side on uneven pavement

⭐ 16,000 lbs Dual-Leg Lift

• Two AJ-series 3.5" × 3.5" tube-in-tube legs
• 24" stroke each
• Bolts to the front of a gooseneck trailer

⭐ 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 (8415AMUPS)

• Two AJ-series 24" stroke jacks
• Commercial single-function pump with screw-drive manual override
• 2-function manual selector valve (1488T) for independent leg control
• Steel pump cover
• Weatherproof keyed switchgear
• 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.
