Once you’re parked and ready to set up, a stable trailer makes all the difference. This stabilizer jack keeps things steady while you load, unload, or camp, reducing rocking and movement. The drop leg travel of 6-1/2" gives you flexibility to match uneven ground, while the large 4" x 3-1/2" foot provides a solid stance. It supports up to 1,000 lbs and lifts up to 650 lbs, so your setup stays firm and balanced.
Getting your trailer level shouldn’t be a chore. The spring-loaded lever lets the leg telescope quickly to the right height, and the folding design flips the jack up for travel or down for use in seconds. You can fine-tune the height using the optional steel handle (part # SJ-100-HD, sold separately). When retracted it’s 11-1/2", extending to 18", giving you reliable range for most camping or storage spots.
Durability matters when your gear lives outside. This stabilizer jack uses sturdy steel construction with a black powder coat finish that resists corrosion from rain and road grime. Reviewers note that even after repeated use, it holds strong without wobble or bending—perfect for regular campers who want dependable support season after season.
Whether you’re upgrading worn factory jacks or adding new stabilization points, installation is straightforward. The 4" long x 1-7/8" wide mounting plate has 7/16" diameter holes spaced 3" on center, ready for either bolt-on or weld-on attachment (hardware not included). Once installed, this compact jack folds neatly against the frame when not in use for clean clearance on the road.
This jack is designed to stabilize a portion of your trailer's weight, not to support the full GVWR of your trailer. Do not use this jack to lift your trailer or RV. Doing so will exceed the capacity of the jack.

I have hauled my trailer all over the East Coast, and I have had no issues with my jack. It keeps the trailer where I put it.

It has been a year since my review, and 2 years since I installed the jack, and it is holding up no pun intended nicely. The trailer is stored outdoors, so the jack is exposed to the weather, but I dont use the trailer much, so it isnt exposed to much road grime.

Excellent! Next motorcycle trailer build will have the exact same set up. Works extremely well and holds the trailer in place.

Thanks for taking the time to follow up with me. No complaints and the stabilizer jack stand still works as it should.

So far the stabilizers have done their job. Im not rough on my equipment, keeping it painted where needed and a thin sheen of oil where parts rub together. If I had to do over, Id get scissor stabilizer jacks that can be raised and lowered with a drill.

How did you mount your stabilizer? In the pictures you put on e-trailer.com of your application, I cant see any bolt holes in the trailer tongue, but it appears you installed the stabilizer on a plate of some sort mounted underneath the trailer.

I cut 2 pieces of 1/4 inch thick aluminum plate one to fit inside the trailor tongue and the other one to fit between the trailor tongue and the mounting bracket on top of the load stabilizer. I machined a shoulder on the bottom face of the aluminum plate inside the trailor tongue and I also machined another shoulder on the top face of the aluminum plate between the stabilizer and the trailor tongue. I also transferred the two holes on the top of the load stabilizer to the aluminum plates and drilled through holes to match that size in both plates. Now to mount you put the one plate inside the tongue with the shoulder facing down lined up with the gap in the underside of the tongue the other plate goes on top of the load stabilizer with the sholder faceing up to also line up with gap in the underside of the tongue now put 2 bolts through the holes in the load stabilizer mounting bracket faceing up through both aluminum plates and install lock washers and nuts then tighten down after sliding the stabilizer forward or backward to your desired location. The reason for the shoulders is so the whole unit wont twist when mounted. Also the shoulder thickness of both plates added together cant be thicker than the thickness of the tongue material or the mount wont tighten up enough to prevent it from sliding back and forth on the tongue. I hope this helps. This system works without having to drill any holes th the trailor tongue and also looks good and clean mounted.
