Camco Eaz-Lift 48131 Adjustable Hi/Low Hitch Shank, 14 Inch

The Camco Eaz-Lift 48131 is the adjustable hi/low hitch shank that lets you dial in the right ball height before you back down the ramp. It's a 14-inch shank built to slide into a standard 2 inch by 2 inch receiver, and it gives you 8-3/4 inches of rise or 5-3/4 inches of drop depending on which way you run it. That range covers most of the height mismatches you'll run into between a truck receiver and a boat or utility trailer coupler.

Here's why that matters. When your trailer sits nose-high or nose-low behind the truck, the whole rig tows worse. A level trailer tracks straighter, brakes more evenly, and keeps weight where it belongs on the axles. This shank is the part that fixes that. You mount your ball or weight-distribution head to the shank, set the height, and lock it in. Get it level once and towing gets a lot calmer.

We reach for adjustable shanks like this one all the time at the shop, because trailers and tow vehicles rarely line up out of the box. A lifted truck sits high. A loaded boat trailer sits low. One weekend you're pulling the bass boat, the next you've hooked up a utility trailer with a different coupler height. Instead of buying a fixed drop mount for every combination, you set the 48131 to what you need and go.

The 48131 is a shank only. There's no ball and no weight-distribution bars in the box, so you'll pair it with the ball or Eaz-Lift head that matches your trailer's coupler and tongue weight. That's by design. It keeps the shank flexible across different setups, and it lets you match the ball size and capacity to the trailer instead of being stuck with whatever came bolted on.

Flipping between rise and drop is straightforward. Pull the shank, turn it over, and reinstall so the taller side or the lower side faces up, then set your ball plate to the hole that levels the trailer. Because it's adjustable in the vertical plane, you're not limited to a single fixed height the way a welded drop mount would be.

Fitment is the usual 2 inch square receiver, the most common size on half-ton and three-quarter-ton trucks and most SUVs rated to tow a boat. Measure your receiver opening before you order. If you're running a 2-1/2 inch receiver you'd need an adapter or a different shank, and this one is built for the 2 inch by 2 inch opening.

A few honest install notes from experience. Check that your hitch pin hole lines up cleanly before you load the trailer, and carry a 5/8 inch pin if your receiver uses the larger hole. If you tow near salt water, hit the adjustment holes and threads with a little grease at install and again at the end of the season. Steel and salt don't get along, and a quick coat of grease keeps the adjustment holes from seizing so the shank still moves next spring. And measure your receiver height off the ground first, because a tall shank on an already-tall truck can put the ball higher than you want.

Who's this for? Anyone towing a boat, jet ski, or utility trailer who wants the coupler sitting level behind the truck. Anyone with a lifted or lowered tow vehicle that a standard fixed mount won't level. And anyone who swaps between trailers and is tired of owning a drawer full of single-height ball mounts. Set it once for each trailer, mark the hole, and you're set.

What it isn't. It's not a complete hitch, and it's not a ball mount with a ball already on it. It's the adjustable shank that the rest of your setup bolts to. Match it with the right ball and, if your trailer's heavy enough to need it, the correct weight-distribution head and bars. Do that and the 48131 gives you a clean, level, repeatable tow every time you hook up.
