With an 8,000 lb lifting capacity and a 20-inch stroke, this jack replaces the frustrating effort of cranking a manual jack by putting full control at the touch of a rocker switch. The AJ series features a rugged 3.5\" x 3.5\" square tube-in-tube design that bolts directly to the center tube of your gooseneck, delivering a clean and reliable installation.\n\u003c\/p\u003e\n\u003cp\u003e\n  Whether you're hooking up a loaded horse trailer on a tight schedule or backing in after a long haul, this system turns a laborious task into a two-minute operation. A built-in manual override screw drive ensures you're never stranded if power is unavailable, giving you the confidence to take this system anywhere your trailer goes. Built by EQ Systems in Cassopolis, Michigan, this jack is a trusted solution for horse trailer owners, motorsports haulers, and commercial operators who demand dependable performance mile after mile.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e8,000 lb Lifting Capacity:\u003c\/strong\u003e Handles fully loaded horse trailers, motorsports rigs, and heavy cargo goosenecks with ease.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e20\" Stroke Length:\u003c\/strong\u003e Generous stroke range accommodates a wide variety of gooseneck trailer heights and hookup scenarios.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3.5\" x 3.5\" Tube-in-Tube Construction:\u003c\/strong\u003e AJ series square tube design provides a strong, stable lifting platform built for demanding environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRocker Switch Control:\u003c\/strong\u003e Weatherproof switchgear with rocker switch and key replaces manual cranking - includes key lock to prevent unauthorized use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManual Override Screw Drive:\u003c\/strong\u003e If power is lost, the jack can be operated with a reversible drill (min. 2000 RPM) and a 6mm Allen hex key through the override shaft on top of the motor.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommercial Single Function Pump:\u003c\/strong\u003e Heavy-duty pump with steel cover is built for reliable, repeated use in tough trailer environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePVC High-Temperature Nylon Braid Wire Harnesses:\u003c\/strong\u003e Harnesses are sheathed for maximum durability in extreme heat and harsh outdoor conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Mounting Brackets Included:\u003c\/strong\u003e Brackets are included with the jack; mounting bolt kit #7227 is sold separately.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWireless Remote Compatible:\u003c\/strong\u003e Accepts optional wireless remote control (part #7823) for added convenience and flexibility.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDexron III ATF Fluid Compatibility:\u003c\/strong\u003e Runs on readily available Dexron III ATF for straightforward maintenance and servicing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eAJ single-leg hydraulic trailer jack (20\" stroke)\u003c\/li\u003e\n  \u003cli\u003eCommercial single function pump with manual override screw drive\u003c\/li\u003e\n  \u003cli\u003eSteel pump cover\u003c\/li\u003e\n  \u003cli\u003eWeatherproof switchgear control with rocker switch and key\u003c\/li\u003e\n  \u003cli\u003eUniversal mounting brackets\u003c\/li\u003e\n  \u003cli\u003eWire harnesses with PVC high-temperature nylon braid\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhy You'll Love It\u003c\/h2\u003e\n\u003cp\u003e\n  Horse trailer and gooseneck owners know the frustration of cranking a manual jack on a loaded rig - the AJ Hydraulic Jack eliminates that entirely, turning a multi-minute ordeal into a quick, effortless operation.
