Stop your trailer, camper, or RV from rocking and swaying when parked! This heavy-duty stabilizer jack is built to lock things down. It's a swing-down design that folds up neatly for travel and swings down when you need stability. The telescoping tube adjusts from about 11.4 inches to 17.9 inches (290mm to 455mm), and it can lift up to 6.5 inches (165mm) to level your rig. It's seriously strong: each jack can support 650 lbs and has a 1000 lb lifting capacity. Made from industrial-grade iron that's weather-resistant and built to last. Installation is straightforward—mount it to your trailer frame. Perfect for utility trailers, cargo trailers, motorcycle trailers, concession stands, campers, and more. Get rid of that annoying wobble when you walk inside, and enjoy a stable, secure setup wherever you park. A simple, effective upgrade for any trailer owner. Pair them for even more stability. Don't just park it—secure it.
