AJ 2/24 Jack System
Description
The AJ 2/24 Jack System is a complete dual-leg hydraulic lifting system engineered to bolt directly to the front of a gooseneck trailer. Built around the AJ series 3.5" x 3.5" square tube-in-tube design, it delivers a combined lifting capacity of 16,000 lbs across two legs with a 24" stroke - making it one of the most capable front jacks available for loaded horse, motorsports, and cargo trailers.
A single weatherproof rocker switch runs both legs in perfect tandem, turning what used to be a grueling manual crank session into a clean two-minute hookup. Whether you're a weekend racer or a working horse trailer operator, this system eliminates the struggle and gets you on the road faster with less wear and tear on your body and your equipment.
Key Features
- 16,000 lb Lifting Capacity: Combined dual-leg rating handles fully loaded horse, motorsports, and cargo gooseneck trailers with confidence.
- 24" Stroke Length: Generous stroke provides ample range for raising and lowering even with significant hitch height variation.
- 3.5" x 3.5" Tube-in-Tube Design (AJ Series): Heavy-duty square tube construction delivers exceptional rigidity and long-term durability under load.
- Single Rocker Switch Control: Both legs operate in tandem from one weatherproof switchgear panel - no more cranking each leg separately.
- Weatherproof Switchgear with Key Lock: Standard key-lock control prevents unauthorized use and stands up to harsh outdoor environments.
- Manual Override - Screw Drive Output Shaft: If power is lost, a reversible drill (min. 2000 RPM) with a 6mm Allen hex key can extend or retract the jack through the motor's override shaft.
- Commercial Single-Function Pump: Heavy-duty pump with steel cover is built for reliable, long-service operation in demanding motorsports and agricultural environments.
- Universal Mounting Brackets Included: Fits a wide range of gooseneck trailer configurations right out of the box - note: mounting bolt kit #7227 sold separately.
- High-Temperature PVC Nylon Braid Wire Harnesses: Wiring is protected by a tough braid designed to hold up in extreme conditions.
- Wireless Remote Compatible: Optional wireless remote (part #7823) available for added convenience during hookup.

FAQ
Does the AJ 2/24 Jack System come ready to use out of the box?
Not quite - the unit ships without hydraulic fluid or mounting bolts. You'll need to order mounting bolt kit #7227 separately (two kits for a dual-leg system) and fill the reservoir with Dexron III ATF to about one inch below the top with the jacks fully retracted. Make sure to replace the shipping plug with the vented breather cap before operating, or the jack may behave erratically.
What happens if the jack loses power while in use?
The AJ 2/24 includes a manual override via a screw drive output shaft on top of the motor. Remove the pump cover and the foil seal, then use a reversible drill capable of at least 2000 RPM with a 6mm (1/4") Allen hex key to drive the shaft. Clockwise retracts the jack; counterclockwise extends it. Be careful not to let the drill contact any wires or hoses during the process.
Can I add a wireless remote to this system?
Yes - the AJ 2/24 is compatible with the optional wireless remote, part #7823, available as an add-on. This is a great upgrade if you frequently hook up solo and want to operate the jack from outside the cab or from the trailer hitch area.
What kind of battery does this jack system require?
EQ Systems recommends using a battery that can deliver a minimum of 150 amperes at no less than 10.5 VDC for at least 30 seconds. Keep terminals clean and corrosion-free. If the trailer sits between trips, the Stay Charge harness kits (#8400 and #8427) will keep the battery topped up from the tow vehicle, and the optional solar kit (#70487) provides additional maintenance charging.
How often does the AJ 2/24 need maintenance?
EQ Systems recommends inspecting the system every 12 months. During each inspection, check that all connections are tight and free of corrosion - particularly the ground connection to the pump stud and the positive cable to the motor solenoid. Keeping up with this simple annual check will help ensure reliable operation for years to come.
Is this jack compatible with all gooseneck trailers?
The AJ 2/24 is designed to bolt to the front of gooseneck trailers and comes with universal mounting brackets to fit a wide range of configurations. It is particularly well suited to loaded horse trailers, motorsports haulers, and cargo trailers. If you have questions about compatibility with a specific trailer, contact EQ Systems at 1-800-846-9659 for guidance.
