RVSHARK RV Slide Out Support Jacks Set of 2 (6000lbs Heavy-Duty), Adjustable 20"–49" With Drill or Handle

The essentials

If your RV slide-outs feel like they’re never quite as steady as you’d like when parked, these RVSHARK slide out support jacks are designed to help. Over the paper, the idea is simple: add solid, adjustable support under the slide-out so it doesn’t sag, rock, or sway while you’re using the space.

You get a set of two heavy-duty jacks meant for stabilizing a slide-out when camping or staying put. They’re built around high-strength alloy steel and reinforced galvanized tubes, with a black powder-coated finish to help resist rust and corrosion. That combination is aimed at one thing most owners care about: confidence that the supports can handle real outdoor use.

That said, there’s an important limitation in the description: these jacks are not intended to lift the full weight of the vehicle or to act as a leveling system. If you’re shopping for something to do full RV leveling, you may need to look elsewhere.

What’s worth noting before you buy

The two biggest buying criteria here are the lifting range and the intended job.

These jacks have an adjustable height range from 20 to 49 inches using a quick-adjust drop leg. The “3-level adjustment” approach is described as helping you dial in the fit without relying on extra wooden blocks, which is nice if you’ve ever had to rummage for spare supports mid-setup.

Also, operation is flexible: you can lift using a cordless drill (described as 20–24V) or use the detachable side handle for manual control. There’s even mention that the optimized gear mechanism reduces physical effort by 20%, aiming to avoid the “stiff cranking” some people run into with other manual jacks.

One doubt to keep in mind: the package includes a drill socket, but a cordless drill is not included. So if you don’t already have a compatible 20–24V drill on hand, you’ll either need one or plan to rely on the handle.

Key features that affect day-to-day use

On paper, the non-slip support plate is meant to fit slide-out frames securely. That matters because the plate is what sits under the frame during support—if it doesn’t grip well, you can end up with more movement than you wanted.

The build also targets longevity: galvanized inner tube plus black powder-coated finish for double protection against corrosion. For travel trailer accessories that spend time outside, that’s a practical focus rather than just marketing.

And the “set of 2” matters because slide-outs typically benefit from support on both sides/points, especially if you’re trying to reduce rocking while parked. The description explicitly calls out reducing rocking and providing additional support for RV slide-outs.

Who it suits—and who should think twice

These RV slide out support jacks make sense if you primarily want stability while the slide-out is extended. If your goal is less movement and less worry about sagging or swaying during use, they’re aimed exactly at that.

It may not suit you if you’re expecting these jacks to level the RV or lift the full vehicle weight. The product description is clear that they’re for support/stabilizing the slide-out, not for overall leveling.

How to use it (simple setup example)

A realistic scenario: you park, extend the slide-out, and notice the area feels a bit unsteady. You adjust each jack’s height within the 20–49 inch range, then position the non-slip support plate under the appropriate slide-out frame area. After that, you lift to take up slack—using your cordless drill for faster setup or the side handle if you prefer manual control.

The aim isn’t to “jack the whole RV up.” It’s to bring the slide-out support into play so the extended room sits steadier while you cook, lounge, or just move around.

Final verdict

Is it worth it?

Worth considering if your priority is slide-out stabilization while parked and you want adjustable supports that can be operated with a cordless drill or a manual handle. The 20"–49" range and the quick-adjust drop leg are especially relevant if your RV setup varies from trip to trip.

Better avoided if you need a leveling solution or a jack meant to lift the entire vehicle—these aren’t positioned for that job. And if you don’t already own a compatible 20–24V cordless drill, factor in that the drill is not included, even though a drill socket is.
