Getting your trailer leveled or lifted doesn’t have to mean endless cranking. This etrailer Boat Trailer Jack combines 15-3/8" of lift with 13-3/4" of drop leg adjustment for a total adjustment of 29-1/8". Just pull the pin to drop the leg, and you’ve already made up most of the distance to the ground. The 7-1/2" long x 3-3/4" wide footplate spreads weight evenly and keeps the jack from sinking into soft ground. It’s a big upgrade from wheeled jacks that twist or roll when parked on dirt.
Rain, salt spray, and road grime are no match for the clear zinc finish on this jack. It’s designed to resist rust and corrosion, even in harsh marine use, with a 100-hour salt spray rating. Heavy-duty steel construction keeps it solid for years of use, and the square tube design adds rigidity where round tubes can flex. Reviewers using it daily around saltwater ramps noted it stayed smooth and dependable well past the first season.
The side-mounted handle gives you room to turn without scraping your knuckles on the trailer frame. Its 7-7/8" handle radius provides smooth leverage, and the built-in grease zerk makes maintenance simple—just a few pumps when the handle starts to feel stiff, no disassembly needed. Owners love how easily it cranks, even under heavy load, and how the gearing feels tighter and smoother than cheaper replacement jacks.
No welding or drilling required—this jack bolts around frames up to 5" tall x 3" wide with the included mounting bracket and 3/8" hardware. The bracket height measures 7-1/4" retracted and 22-5/8" extended, giving plenty of range without hitting toolboxes or winch posts. Whether you’re replacing a worn-out OEM jack or adding support to a work platform or custom trailer, this 2,500-lb-capacity unit goes on cleanly and works right away.
This jack doesn’t swivel, twist, or ride on a weak pivot pin. It’s a fixed-mount square jack that stays rock solid when you set it down. The flat footplate keeps your load steady, whether you’re supporting a heavy trailer tongue or just leveling for drainage. Once you’ve used a solid square-tube jack like this one, you won’t go back to a wobbly wheel type again.

Works well except the crank handle is very rusty and will need some sanding and paint.

After a year Jack still works like new. This is the only one I would buy as I’ve had several in the past with the wheel that were unstable and unsafe. Remember to grease the fitting on the standard at least once a year.

After a year of use, the trailer jack is still working like a champ! Replacing a wheeled stand was a good call. The boat is too heavy to roll around and only increases the risk of rolling down the driveway.

after a year of use the jack is still working as it should. The only issue is rust accumulation at the foot of the peg, but I think thats more of a local environment issue than the product itself. perfect replacement for our small boat
