The Trailer Valet JX7-S is a heavy-duty side-mount trailer jack engineered for users who demand speed, comfort, and durability when working with heavy trailers. It holds a 7,000 lb static capacity and lifts loads up to 1,800 lbs manually or 900 lbs when powered by any standard 20–24V cordless drill using the included drill attachment, making hitching and unhitching even the heaviest trailers fast and effortless.

The JX7-S delivers 27.3 inches of total height adjustment through a combination of 13.6 inches of vertical lift and a 13.7-inch adjustable drop leg, with a retracted height of 23 inches and a maximum extended height of 49.5 inches. The heavy-duty square drop leg includes a welded-on footplate for a stable foundation during loading and unloading. Installation is bolt-on with no welding required — the larger mounting bracket accommodates trailer frames up to 6 inches high and 3.75 inches deep, with 6.4 inches of spacing between holes for a precise fit.

Constructed with three layers of corrosion protection — zinc-rich coating, nickel plating, and a wrinkle black powder coat finish — the JX7-S is built to outlast standard trailer jacks in harsh outdoor environments. An integrated weather sleeve reduces friction and shields internal components from the elements, while a patented 3:4 gear system minimizes heat retention for smooth, long-lasting operation. Built-in Warning and Stop indicators at both the top and bottom of the inner tube prevent over-extension and protect the gear mechanism. The unit weighs 27.5 lbs and includes the jack, drill attachment, hand crank, footplate, and all mounting bracket hardware. Backed by a 1-year manufacturer's limited warranty.
