For Comparison’s Sake: Trailer Jacks

We compare some of the top trailer jacks for boaters.

When you think of a jack for your boat trailer, you envision a tongue-mounted model that you use to raise and lower it onto the tow vehicle’s hitch. But there are times when you need to pick up the back end of a trailer as well. Here are the three most popular ways to get the job done.

Dutton-Lainson 6816
The Up: The fixed-style jack has a sturdy steel footplate and a 2,000-pound capacity, so it can handle a big trailer. It has 15 inches of travel and is designed for tongues up to 25 inches off the ground. It fits tongues up to 3 inches by 5 inches.

The Down: Even when fully raised, the footplate still hangs below the trailer frame, lowering clearance, and the lack of a wheel means you can’t move the trailer around in a parking lot. $75;


Springfield Quick-Change
The Up: Place this ­aluminum jack under square or round axles and then pull forward to lift up to a 4,000-pound trailer off the ground. It’s also conveniently ­portable, so you can use it on more than one trailer. It fits wheel sizes from 10 to 15 inches, so it’s also versatile.

The Down: If you need to change a flat on a soft shoulder, gravel or a dirt road, it may skid and take a few attempts to work as advertised. $42;

Dutton-Lainson 6400
The Up: This is the most widely used type because it rotates to a horizontal towing position and locks in place parallel to the trailer frame. The wheel makes it easy to move around on a paved surface. It fits tongues up to 3 inches by 5 inches.


The Down: It has a limited weight capacity (1,000 pounds) compared with heavier-duty nonswiveling models. Also, watch the handle so it doesn’t drag in low-profile applications. $60;
