Soft dirt, gravel, or uneven rock can make it tough to keep a trailer still. These Ark XO Drop Down Corner RV Stabilizer Jacks use load-bearing feet and an articulating footplate that adjust to flat or uneven terrain, so your setup stays firm wherever you park. With a combined support capacity of 3,850 lbs and up to 6" of lift, you get a solid, steady base when unloading cargo or changing a tire.
When you’re out in the elements, you want gear that lasts. Each jack is made from steel with a corrosion- and rust-resistant black powder coat finish tested for a 600-hour salt spray rating. That kind of durability makes these jacks a clear upgrade from lighter factory setups and keeps them in shape through repeated exposure to rain, mud, and road debris.
Finding balance on uneven terrain is simple thanks to the twin pin locking swivel bracket. It gives a range of deployment angles so you can set each leg where it needs to be and still stay within the tested 25" max bracket height. The included winding handle lets you raise or lower the jacks smoothly by hand, or you can use an impact driver for faster lift times.
Once you’re leveled and locked in, you don’t want extra parts hanging down. These stabilizers fully retract when not in use, keeping them protected during travel. Each leg weighs about 15 lbs and includes molded jacking instructions on the cap for quick reference—so setup is straightforward every time.
Designed as both stabilizers and jacks, these legs handle day-to-day tasks like leveling at camp or lifting a corner to swap a tire. The stronger 19 mm hex drive works with standard winding handles, a wheel brace, or an impact driver for flexibility in how you operate them. It’s a reliable setup that brings solid footing and versatility wherever your trailer ends up.

Ratings & Reviews
I like the jacks,I didn't weld what was told,I drilled holes in the mounting bracket counter sunk for bolts, I drilled and taped holes to screw mounting bracket to frame, then I used brass angle iron to bolt to mounting bracket and trailer frame to make sure all was secure, bolted everything on to frame using stainless steel bolts and the brackets are brass,so noting rust. I fell much more confident on the way I mounted the jacks ratter then welding and have no distortion or messing up the trailer frame. Very happy on how I did it and it works great.
Can’t believe these weren’t installed at the manufacturer. These are an absolute must for anyone owning an overland camper trailer!!!
These were a great addition to my custom army overland trailer, m1101 they are super easy to use and work perfect to level out when it's time to camp
Works perfectly to level my off road trailer/camper. Gives my camper a solid footing on any terrain. Easy to mount and operate. They fold up tightly against the frame and don't affect ground clearance whatsoever. Would buy again.
Easy and quick to replace. Seem stronger than OEM and the extra 3-4” makes a big difference!
Perfect match for the Blackseries trailer. Very easy to install.
Fast shipping and excellent customer service. Jeremy was very helpful selecting the correct part.
In use full time, these are simple to use and low profile (so they don't drag and get destroyed). Only negative is they are difficult to release. They've gotten easier (or I've been trained) over time.
Awesome Jack Stabilizers. Very Easy to Install. Great Quality!
These are so great, I'm buying two more for the back of the camper to replace the originals. Easy-to-use, quick setup.
These are incredible! I have a teardrop camper that came with "scissor" type stabilizers, and they almost immediately broke. They were very difficult to raise and lower and I needed an impact drill to make them work, only weeks after delivery. Unfortunately the company went out of business and I was forced to find my own solution. eTrailer.com to the rescue!
I bought 2 sets so I could have one on each corner of my Teardrop Camper. I got them welded locally for just over $300, and couldn't be happier. These drop down straight with just a bit of ground clearance. Although the primary purpose is stabilization, I could use these to jack up the whole side of my camper to change a tire now. No more going underneath and jacking it up manually anymore. I love how they can be set at an angle or straight up and down. My only question is why didn't the builder of my camper put these on in the first place! If I am going to have stabilizers that are used every time I go out, why not have the best? Love these, highly recommend.
Great service arried promptly and in good condition. Easy install, fit existing brackets on my trailer
Great product that bolts straight onto my Blackseries HQ21. Very fast shipping and great customer support!
Work great. I got 4 to stabilize our tent trailer. I added rubber mat pads under the bottom plate to increase the friction/grab on the ground.
Perfect fit for a 2019 Black Series HQ12. These units come with a bracket for welding to the frame but these new units bolted right into the existing bracket. The bolt hardware is not as robust as the original hardware which is bigger and stainless steel but the included hardware work none the less. These ARK units are much heavier and robust than the stock stabilizers. They extend a bit slowly (takes more turns) but that's a nit pick but there is an included drill/driver socket to use on a powered drill if that's your preference. I just use my standard 4 way tire iron as it's multi function and doesn't rely on battery power. I only needed one but these come as a set and so I replaced both in about 5 minutes.
I've installed the Ark Stabilizer Jacks replacing the typical scissor jacks.
Love how much cleaner the Arc Jacks look and so far seem much more stable! Going camping this weekend so Im anxious trying them out!
Solid
Great product , There are far better off road stabilizers but for the value these work. logistics from E trailer did not go so well , delivery was not as promised. I will be returning these for a refund - as I had to source elsewhere to make a trip. e trailer tries but often falls short in the shipping department.
I just received our new stabilizer jacks yesterday. Hoping to get them installed at the end of next week. Overall very pleased with the quality of our new jacks and looking forward to how they perform on our travel trailer. E trailer is an amazing company if your looking for products for your rv. I also have pads for the new jacks to put under when in use arriving tomorrow. E trailer is extremely organized from there ordering process, quality of products, knowledge and videos of products and prompt delivery. HIGHLY! Recommend e trailer
Over engineered in all the right places! These stabilizers/ jacks are beasts and will not let you down!

Beyond what I expected in all positive ways. I have one on each corner of my beach fishing trailer. Salt and the sand every day all day and they still work like they did out of the box. My clients are on top of the trailer reeling in large fish some 500+ pounds and the trailer has been 100 solid and stable every time. Thank you so much for an amazing product. Hard to find quality like this these days. Thanks again.
