JT's Strong Arm Travel Trailer Jack Stabilizer Kit, Bolt-On Installation, Universal Compatibility, Telescoping Tubes, Eliminates Chassis Movement - 191025

We use these stabilizer bars on our electric-motor RV stabilizers. Real easy to install once we looked at other online posts of installations (no instructions - looked at pictures of other folks who bought this and posted how they did it). These are HIGH QUALITY solid stabilizer bars. Comes with all the hardware you need. I would recommend the manufacturer send self-drilling screws (would make a quick installation even quicker), but my electric drill did the trick. Overall, very satisfied.

My order came double-boxed and the kit inside the inner box was cushioned with styrofoam, so it is packaged well. The kit from Amazon does not come with any instructions whatsoever, but I'm still giving the product 5 stars, because that has nothing to do with Lippert or JT's Strong Arms and everything to do with Amazon. You can find the instructions fairly easily online. Just search for JT's Strong Arms installation instructions and they'll pop up. You can also watch YouTube videos. There are a number of them out there. Installation requires you to be somewhat handy. You will need to tap new threads in your trailer frame, because the self-tapping bolts that are included with the kit will NOT self-tap into the steel frame. Make sure you have some good quality, sharp drill bits to drill your pilot holes. Mine were not very sharp and took me a while to finally break through. That's on me though. I'd say getting the pilot holes drilled and the threads tapped was by far the hardest part of the whole install. Getting all the hardware bolted together to get the supports ready to install is also pretty time consuming. The whole job should probably take you about two to three hours if you have all the tools ready. The product does exactly what it says it will do. It removes almost all motion inside the trailer from people moving around. It does not take all the motion out, but I'd say it does away with about 90% of it and that's good enough for me. If you go into with that expectation, you won't be disappointed.

Once installed these work very good. They don't take away all the trailer movement but they do a lot. After installing them and setting my trailer to the suggested instructions it does work very good. The biggest draw back was the install, my current scissor jacks had small bolts on the bottom then what was provided for the strong arms, so I had to drill out all the holes for the bolts that came with the strong-arms. After drilling out all the holes though it was pretty easy to get everything set up and bolted in. I had to put 4 in the back and 2 in the front because my front jacks are set at an angle. The kit also comes with plenty of hardware to install how you want. I would say that you can review the guides on how to install but then choose how to install on your own. all in all these are great!

Package arrived on time. System was missing one self tapping bolt/screw. Instruction are almost useless. Pictures in instructions are completely useless. As a professional welder and fabricator since 1978 this is a decent product, built well and seems solid. I attached this system to a thirty three foot Coachmen travel trailer with serious stability problems while stationary. I elected before hand to use four bars at the rear of the trailer and the remaining two bars at the front. I truly believe this system should come standard with eight arms not six. The eight self tappers do work when used properly pre-drilling with a self centering 5/16" drill bit. Be careful where you use the 3/8" washers as the exact amount and no more are provided. The t-handles provided to lock down the two piece bars are in a bad location but I really don't see a viable alternative. After installation I rechecked each and every piece, you do not want this coming apart traveling down the interstate. The BAL jacks I attached this system to were a perfect fit for this item. This is a great system and I gave four stars because for the money they could have at least provided decent instructions and ALL the parts. Anyone with basic skills with a drill and wrenches and a tape measure should be able to install this system in one day if not two. My trailer is now rock solid steady. Also, if you don't like the gaudy decal on each of the six stabelizers, they peel right off. It's late August and I wanted to add a tip that many may have missed in the instructions. After deploying your jacks and tightening the bars, apply a little more down pressure to each jack. This will take out a little more wiggle in the trailer. UPDATE: a four week trip to Arizona with our seventh stop in Sonoran desert. Been here two months and stabilizer system has made all the difference. Every three weeks or so the jack pads settle into the desert floor so I re-adjust all four corners and its no fault of the stabilizers. Best money I've spent in a long time. Highly recomended.

We have been camping for the past 3 seasons with our Jayco Jay Flight SLX 184BS and it rocks when we are moving about in the travel trailer even with upgraded jacks. E-trailer wanted over $300 for this JT StrongArm. eBay for imitation brands are about $140-$160. So, I decided to buy LCI JT StrongArm from Amazon for $175. The item came but it was missing the 6 T-bolts and installation manual. The tubes look and feel sturdy. I'm waiting for replacement parts from LCI. I deducted 1 star because I have to waste time to resolve this. Update - July 2025 I strongly recommend this product! JT Strong Arm made a huge difference! I upgraded my Jayco Jay Flight 184BS with 9,000 lbs rated jacks the first year we bought the travel trailer and I only saw little improvements. Then, I used a couple of the old jacks to support under our slider and steps. That, too, only made a small improvement. As my kids get older, their movements shake our travel trailer quite a bit. With this JT Strong Arm, it made a huge difference and the best bang for my bucks! Looking back, I should have done this first then upgrade the jacks but don't need to get 9,000 lbs rated. So, I revised my rating back to a 5 star.

We were looking for a way to make our travel trailer more stable when our two young children were moving (running/jumping) around inside when parked. This system eliminated 95% of the movement. The instructions were useless, but all the parts (and more) were included with the kit- you just have to get creative and make up your own plans. You will need At least a power drill, sharp drill bit for metal, and the appropriate wrenches/sockets. I also used a step drill bit, and a tap to put threads in the metal- not necessary, but highly recommended. We ended up putting 4 strong arms in the back (2 front to back, and 2 side to side) and 2 in the front (front to back only), even though the instructions called for 4 up front. My trailer didn’t have the cross member to mount to that the instructions called for. The bulk of the movement comes from the rear bunkhouse anyway, and this setup worked fine for us. Would absolutely buy again despite the frustrating install. If you can drill a hole in metal, you can install these!

I have used JT strong arms on an older trailer years ago and they worked perfectly no issues putting them on. super simple. However my new trailer (which is a 2021 Jaco jay feather 25rb) came with the BAL LO PRO24 scissor jacks. And apparently has a much larger larger foot pad on the scissor jacks. The description says that it will fit most trailers but not all and does not specify a maximum width. I did order the travel trailer version to the best of my knowledge. In the instructions that I downloaded, because none came in the box, it expressly references 5-in swivel bolts however the package comes with 4-in swivel bolts. Instructions do note that if the bolts are too long to use multiple washers to adjust but no options for if the bolts are too short. The issue for me is that the width of the arm on my scissor jacks foot is 3 and 3/4 in. You're instructed to use the 4-in swivel bolt, two washers and a nut. With the washers the nut does not bite enough and stay on the foot. I called lippert customer service requesting the 5-in swivel bolts notated in the online instructions and they do not have any nor are they available anywhere online that I could find.

I thought the instructions were well written and easy to follow. Installation went easy. Set up and back to travel is easy to do with little physical activity.
