Video Transcript for Stromberg Carlson Camper Jack - Stabilizer Jack - JSS-85 Review

Today we're gonna be taking a look at the Stable Step Stabilizer Jack. This jack will help extend the life of your step assembly. Takes around 750 pounds off of your step tread, carrying mechanism and RV frame. They can be used with any step assembly attached to your RV. It simply stabilizes your step assembly making the step assembly more steady as you go in and out of your unit. Really simple installation.

When it's in the in use position it'll look a lot like this. The unit mounts underneath your step and then unfolds to this position when ready for use. When it's not being used you simply fold it up into the housing and secure it in this stowed position or travel-ready position with the pin and clip. So, that keeps it mounted under your step. So, when you get to your destination, when you get your steps out and in place, what you'll need to do is remove that pin, bring the Stable Step down and then it's on a threaded system, so it's on a threaded rod, so that way you can simply unthread it to get the desired height that you need, you know, until that makes contact with the ground and provides the support. Now, it does feature the adjustable height design, it's gonna adjust anywhere from 8" to 15". It's black in color, it's made from a steel construction.

Again, it's gonna feature that capacity of 750 pounds, the area that makes contact with the ground, that's this area right here, that's gonna measure 4" long by 1 1/2". The mounting area, that's this piece right here, it's gonna give us and overall length measurement, going edge to edge, it's gonna measure right around 8". The widest point, which is this end, is gonna be about 1 15/16" wide and then the most narrow point is this end, and that's gonna measure about 1 1/4" to 1 5/16" wide. When it's in the stowed position like this, it's gonna have a height at the thickest point, which is right here, of 1 3/4" tall. The mount holes on the unit are separated on center by 7 1/4", again, it does come with the pin and clip, and it's gonna come with your mounting hardware. That's gonna do it for today's look at the Stable Step Stabilizer Jack..

Replaced a 3 step set of stairs with a 4 set and wanted a little extra support. Product fit well and works great. Had to move it to the next step up, but was a simple modification by just drilling 2 holes in the step. Very well built and nice, clean design. 177714

I have two doors on my unit the front door has a 4 step system and I had to bolt these onto the 2nd step off the ground. For two reasons, 1) I did not have enough clearance from step to ground, 2) Steps would not fold up. The back door on my unit has a 3 step system and I put these on the bottom step and it worked fine. I think I will use a leveling pad or board under each pad so they do not sink into the ground, but they did really help support the steps and take the bounce out. 498165

First unit received was incorrectly assembled from the factory. (the nut was cross threaded onto the threaded rod). Etrailer's customer service was excellent. They sent me a replacement no questions asked. Replacement unit works flawlessly. I would add, if you're on the larger side like me, buy 2 and place one on each side of the step. 499820

Bought these about a year ago and they are one of the best accessories I've ever purchased for our camper. Not only do they make the steps much more stable, I think they take a lot of stress off of the stair support brackets on the trailer. They stow quickly and easily for travel. I suppose you could get by with a single support in the center of the stairs, but I bought two and I'm glad I did. Highly recommend these for any camper! 405394

The supports are everything I had hoped for. They are an awesome addition to our camper!

Easy install. I installed 2 on my steps. Only wish they had a down lock of some sort. 528681

by:

Decided that with a Quad step, a stabilizer jack would be a good idea, but I wanted something that would self-store and always be ready for use. The Stabil-Step seemed to fit this need. If one is good, I thought two would be even better. I was right. The Stabil-Steps work almost perfectly, in tandem, to securely stabilize my step. Although placement, of two Stabil-Steps under a single step, took some careful placement, they work almost perfectly. They both fold and store under the step, and the step folds fine without any obstructions. If the Stabil-Steps were to contain a stiff "internal spring", to retain ground to step tension to compensate for inevitable movement under repeated step traffic, I would rate them excellent! (maybe an upgrade idea for Stabil-Step) 206204

Works great glad that it mounts on and locks up for travel. It takes that creek noise out that you get whenyou use the steps. 150017

by:

I'm glad I ordered this product. It works great to stabilize the steps as we come in and out of the trailer. The wide range of adjustment is what makes this stabilizer. I thought about just one jack in the middle of the step, but in that manly thought process, if one is good two would be better and yes it is. We have NO movement in the steps. There were two things I change and first was the bolts and nuts. It does need a bit larger bolt and I used 10-24, which is about 3/16 bolts. Two was that I had to add a spacer to one side so the pin would slide in. Putting this on the step was as easy as putting a bit in a cordless drill. Don't even need instructions for this install. 260877

I have a recently installed step on my enclosed car trailer, wanted this to stabilize the step. Sadly my lowest step is only 5-6" off the ground, so I put this on the next step up. Made it harder to mount. I drilled the holes to 1/4" and used bigger bolts. The swing arm retaining pin is small, looks to be a weak point in the design, after bolting to underside of step, when retracted the arm contacts the bottom of the nut preventing it from allowing the pin to go in. Some washer shims and smaller length bolts solved the problem. the product seems to help stiffen the step up. Took 14 days to recieve product, may be the postal service fault...... 668562

Product came yesterday looks great not impressed with little bolts to hold them on but I used my son and drilled out little holes and put on i used 2 of these on my steps and think I was good idea for 2 if you use just one the support would only be in middle when you step you typically would not just step in middle just me thinking thanks for quick delivery they came a day earlier than I expected 392976

Great Product. I installed one on both sides to give more support along the entire step. Easy install, the biggest problem (if you want to call it a problem) was positioning them with the contours of the step. 320054

Well build. easy to install. It would be nice if the min. setting would be around 6 inches. On a level surface 8 inches is to high. Many camp grounds strive to keep the rv pads level. 318461

Great news, John! There is a shorter jack with an adjustment range from 4-3/4 to 7-3/4 - it is the Stabil-Step Stabilizer Jack for Step Assembly JSS-4. I hope this helps!

Have a drainage channel down the middle of each step, and had to use spacer washers to attach so I could get the pins in to hold up the legs when not in use. The flange on the step bottom hit the channel and would not get flat. Steps do not drop but will still move fore and aft a bit. 2011 used trailer so will check all bolts and studs for proper fit, and if good may check into more robust step jack. Either way, better than it was so cannot grouse too much. 310247

by:

Product is fine. I should have bought two and mounted them to support the steps on both sides instead of just the middle. That's my recommendation. Buy two. Mount them so the jack extends to the sides of the steps. Stops the rocking motion. Absolutely satisfied with the product itself. 260218

If Id have had these from the beginning, I wouldnt have suffered the failure of the top pivoting rivet.

Exactly what I wanted, short enough to fit under my step by will extend far enough if unlevel pad. Easy install, holes lined up in existing slots on step. Ten minute install. Installed one on each step, made a huge difference on the rocking when stepping in. 257093

If you're worried about putting a strain on your RV steps this is the product that will ease your mind. My son is on the large size, about 280 lbs., and I was concerned about the ability of the steps to take this much weight. This solves the problem. Installation is a snap, only have to drill two holes. Highly recommended. 143631

by:

After having to replace my steps to my fifth wheel because the brackets had split and couldn't find replacement brackets, I decided to put something on the steps to relieve the pressure when they are used. I got two of these stabilizers and installed them on each side of the bottom step. They were simple to install, just drill four holes and attach with included bolts. They provided excellent support and are simple to use. I highly recommend them! 132105

Had to get stronger mounting screws to mount on step but overall very good. Trailer coupler lock did not fit but I might be able to modify coupler tounge on trailer to fit it, (shackle not wide enough, about 1/8 of an inch too narrow on both ends.) or r can i return it and get one that fits? Hitch reciever lock worked great. 121559

Using with the new steps I just installed. Lift the bottom step and adjust this support to the correct height. Lower the bottom step and you have a very steady set of sets and it cuts down on rocking of the trailer. 317174

Review from a similar Stromberg Carlson Stabil-Step in Camper Jack


I bought 2 RV stair supports. One worked perfectly. The other I had to put in a vise and use a hammer to get it to turn to make it adjustable. I should have returned it but I beat it up so badly with the hammer I felt it would not be returnable. After and hour or so of finally getting it to turn (lots of beating it with the hammer) and a lot of oiling it will be usable. A lot of filing and paint and it will look acceptable. Not quite what I expected from etrailer. Other products I have purchased have be as expected. Guess I got the occasional lemon. 228027

Review from a similar Stromberg Carlson Stabil-Step in Camper Jack


Although I'm using the product to support an existing deck which is sagging due to stringers that are cracking due to ground shift, the Stabil Step it will work perfectly for my application. There is not a lot of clearance under the deck so the compact size and its adjustability plus the 750 lb load bearing capacity and powder coat finish for weather exposure are all factors which led me to choose this product. The customer rep I dealt with was extremely helpful and the product was shipped promptly and arrived within 3 days of me placing my order. Etrailer.com is a good e-tailer who has great customer service. I will definitely do business with etrailer.com in the future. 667242

We had othe double sink in our fifth wheel dropping and seperating from it’s counter top surround. I used this item to prop up the sink to its original position. The screw thread length adjusting feature was perfect for my application. There was zero trade off with respect to space utilization on the shelf underneath. If fact, it worked so well I forgot about this project until your follow up question today, Excellent marketing procedure! Regards Bob 598482

This was just what I was looking for to hold up my 250lbs capacity steel desk, that had broken off a leg. Contacting the manufacturer for a replacement part was like trying to break into Fort-Knox so I opted for this jack. Shipping was supper fast and the price was great. Replacing the broken leg on my desk was a piece of cake. Sure wish they had this in a taller size. 563649

  • Could Stabil-Step Stabilizer Jack Be Used On Upper Steps of RV Steps
  • As long as your upper step is compatible with the height range of the Stabil-Step Stabilizer Jack for Step Assembly # JSS-85 then it could work well with it. The height range of this is 8 to 15 inches. Normally people use it just on the bottom step and it does a great job stabilizing the whole setup.

  • What are the Dimensions of the Stabil-Step Stabilizer Jack, # JSS-85
  • I went out to the warehouse and pulled a Stabil-Step Stabilizer Jack, # JSS-85, to take some measurements. The bottom foot is 4 inches by 1-1/2 inches. The top plate is 7-15/16 inches long and 1-1/4 inches wide at the most narrow point, and 1-15/16 inches wide at the widest point. I produced a picture that shows the dimensions for you. Using 2 of these on one step would make the step more stable, but it would not allow the step itself to hold more weight.

  • Recommended Support for Econo Porch Trailer Step
  • The Econo Porch Trailer Step w/ 2 Handrails and Landing - Triple - 7" Drop/Rise, 27-1/2" Tall # EHS-103-R-HR can be used as a back step. Because you will only be using one of the handrails, you may want # EHS-103-R to save that cost. You may be interested in the Stabil-Step Stabilizers # JSS-4, # JSS-7, or # JSS-85 for increased support. There is not a specific rail for the back of the stairs when used as you suggested, so you may want to consider adding a folding handrail like # AC-300...

  • Recommended Econo Porch Trailer Step with Handrail and Optional Stabilizers
  • The Econo Porch Trailer Step with Handrail and Landing - Double - 7" Drop/Rise, 20-1/2" Tall # EHS-102-R does not require a stabilizer. It is a strong step with a weight capacity of 350 lbs. I've attached some videos to assist. The stabilizers like # JSS-4, # JSS-7, and # JSS-85 are available for people who want a stronger and more stable step with the load capacity of 750 lbs. That weight capacity is only directly over the stabilizer, but it more than doubles the capacity.

  • Will Stabil-Step Stabilizers Work with Econo Porch Trailer Step to Help Support Additional Weight
  • I spoke with Stromberg Calrson about the Econo Porch Trailer Step # EHS-102-R that you referenced. She confirmed that the Stabil-Step Stabilizer Jacks can be used to help support additional weight on the Econo Porch. Stabilizers will help increase the weight capacity of the steps, but it is difficult to say by how much due to factors such as quality of stabilizer and the installation process. My contact also recommended anchoring the back of the step to the camper for further support....
