Heavy duty trailer jack delivers stable lifting and safer hookups for RV, boat, and utility trailers up to 12,000 lb. The sidewind handle crank and smooth screw drive make height changes fast, while the square direct weld-on mount and adjustable drop leg help reduce wobble during leveling. Reinforced steel tubes, powder-coated protection, and a thick carbon-steel base are built for repeated use at the campsite, jobsite, or dock.

When tongue weight and uneven ground slow you down, this square weld-on trailer jack keeps your setup controlled and repeatable. Use it to stabilize an RV at camp, lift a utility trailer for loading, or level a boat trailer at the dock—without fighting a sticky crank. The adjustable drop leg and multi-position lifting tube let you dial in the working height to match your trailer and terrain. Upgrade your trailer support and grab yours today.
