AJ Hydraulic Trailer Jack 1/20 with Manual Override Screw Drive

Description

The EQ Systems AJ Hydraulic Trailer Jack is a heavy-duty, single-leg hydraulic lifting system engineered for gooseneck trailers carrying serious loads - horse trailers, motorsports rigs, and cargo haulers. 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.

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.
