If you've got a trailer that needs some serious support, these telescoping jacks are exactly what you're looking for. This two-pack gives you everything needed for stabilizing your pop-up camper, utility trailer, cargo trailer, or motorcycle trailer. The extended reach is awesome - they adjust from 16 inches all the way up to 22.5 inches, which is perfect for trailers that sit a bit higher off the ground. Each jack can handle up to 1,000 pounds, so you know your trailer is going to stay put when it's parked. The black powder coating looks clean and provides decent corrosion resistance. Now, just to be clear - this listing is for the jacks themselves only. You'll need to provide your own bar or handle to actually operate them, plus mounting hardware to install them on your trailer. But if you're handy and have the other components, these are solid quality jacks that'll get the job done. Installation is pretty straightforward if you're comfortable with basic tools - just position them where you need support on your trailer frame, drill your holes, and bolt them on. Having two means you can set up proper support on both sides of your trailer for maximum stability. Way better than trying to balance your trailer on cinder blocks or other sketchy solutions!
