Shaking when you walk inside or swaying in the wind can make your setup feel unsteady. This kit braces your trailer frame using stabilizer bars that form rigid triangles between the jacks and frame to eliminate chassis movement. Once positioned, the T-handles twist tight to lock everything in place so the camper feels solid from front to back.
When spacing is tight, getting the right stabilizer geometry matters. This system is built specifically for setups with less than 58" between front landing gear legs, ensuring proper alignment without modification. The telescoping tubes adjust from 24" to 44" on one end and 27" to 47" on the other for a precise fit every time.
Setting up doesn’t require fabrication work or special tools. The kit bolts directly to common frame types—C-channel, I-beam, or H-beam—so you can get everything mounted with simple hand tools. Each end attaches securely to the landing gear leg and frame using included hardware, no welding needed.
Everything needed to steady both ends of your setup comes in one box. You get six stabilizer tubes—four for the front and two for the rear—plus clevis brackets, stiffening pads, spacer mounts, bolts, nuts, washers, and handles. Every piece works together to create a unified system that resists flexing and keeps movement to a minimum once leveled.
Each component is steel for dependable strength under load. The bolt-on design and telescoping tubes are made to handle repeated use during setup, teardown, or long-term storage. It’s a rugged stabilizing solution backed by a 1-year limited warranty from Lippert for added peace of mind.

I have had the JTs Strong Arm stabilizers on my fifth wheel for a year now and they really make a difference. No more movement felt while walking across the camper or when the kids are wrestling around in the front bunk house.
Etrailer is always a pleasure to deal with.
The Strong Arm stabilizers have worked great. After locking the stabilizers, the majority of trailer movement from walking around in the trailer has been eliminated. I highly recommend.
Every time we camped the Jayco T30F toy hauler seemed to move or sway when walking around in it. Laying in bed the dogs would get a drink and they would layi down which made the trailer feel like it moving or swaying. It felt like I was motion sickness from moving. I ordered the StrongArms after that camping trip. I installed the Strong Arms just before the camp out the following week. It was great no movement. Rock solid like having a foundation under the camper. What a night and day difference. I will install them on any future camper. We like to show off how stable the camper. A must for all campers!
Absolutely love the JT Strong Arms. I get asked about them all the time on our 2016 Jayco 267BHSW. I give them a quick demo with the t-handles loose and with them tightened, virtually no shaking at all any more. The only movement I have is still in the axles/suspension, I can eliminate that further with jacks in front/behind of the wheels, but I'm ok with that little movement for now.
Delivery was prompt and accurate; the stabilizer was double boxed and arrived in tact. I have only installed it and tested it out at home; so far it seems to do what it advertised. The components seem to be high quality and well made. If you have any mechanical ability, installation is easy and straight forward; the instructions give dimensions and a few photos. If your camper is like mine (having 3/4” wide cross brackets) you may want to fabricate a wider bracket to bolt the included 1.5” center brackets to on the front and back. I did this by bolting 2.5” angle iron to the cross beams on the camper.
I'm kind of torn on my star rating. As far as the product goes... yeah 4-star no question. But the instructions and information required to do the job is a 1 or 2.. I'll explain.
First, the good:
The product functions as advertised. It really lessens the trailer shaking considerably. You really have to try to make it shake now where before just walking around made the blind hit the windows.
The hardware is very nice quality.
The bad:
The instructions . They are very wordy and can be confusing if you're not on your game. There should be a lot more pictures. There should be more explaining the adaptation to hydraulic foot pads
I knew I needed to buy the Hydraulic pad adapters but it was not clear when I bought them that I needed 4 and not 2, and in addition to that I needed to buy more swing bolts. I was not very happy about that.
So if you have electric gear you'll probably have everything you need
If you have hydraulic gear be prepared to spend about another $100 for additional hardware, have extra unused hardware from the original kit contents and searching for how these thing should look when finished.
I just installed this on my Jayco 33 ft. fifth wheel. It was huge improvement, as now it feels like walking through a house. If you can make sense of the instructions that come with the package, you are better than me. You Tube videos were a huge help. Installation for the back stabilizer was hard as I didn't order the extender product that was available (I should have got these), so I repurposed extra mounting tabs that came with the package, and welded the extra tabs on the rear mounting feet. There was not a easy access to a cross member on the rear, so I used the rear bumper. I put the nuts into the rear bumper (4" square tubing) on the end of a wrench attached to a long pipe. It was time consuming but the install was worth it.
Made my 5th wheel toy hauler rock solid.
Made the 5th wheel so much better. Hardly any movement. Only took 2 hours to install
Took the sway out 95%. Excellent customer service! Quality product.
Very pleased I made this purchase. It has totally changed the stability of our fifth wheel. Very easy to install and well made.
This is a great for stabilizing a 5th wheel!! Way more affective than a tripod! Easy install for anybody that had a drill and good drill bits!!
Installed the front stabilizers on my 35’ cougar 5er in around 2 hours. The style of our rear electric jack and being insulated requires I add a 3x3 crossmember to anchor to. A job for a latter date.
Just adding the front stabilizers is an improvement over the tripod we were using . One less thing to carry and store.
The installation manual was designed for several different types landing gear which made it a bit confusing. Used Lippert”s installation video.
I installed these on my 2018 Reflection fifth wheel with auto leveling jacks. Instructions are not very clear for rear jacks due to all the different configurations out there. I wish the instructions had more pictures too. On the rear hydraulic jack pads I used the adapter lugs P/N 314592 which meant I needed 2 more swing bolts than what came with the kit. I called Lippert and they sent me 2 more. After everything was installed the rig was solid as could be. Very happy I bought these I really enjoy ordering from you.
These weren’t the easiest to install but man do they make the trailer way more stable. I also added two manual stabilizers under the slide out. The JT Strong Arms and the slide out stabilizers, you can jump around inside and can barely tell. Great addition.
The JT Strongarms have nice thick finish to guard against rust, the install was easy and our 30' fifth wheel is really stable now, feels solid. Worth every penny.
These are great and made our small 5th wheel rock solid, I mean night and day compared to just landing gear and rear stabilizers. I did have to do some minor fabrication for both the front and the rear. The front was due to the spare tire being mounted under the front of our rig. Also the instructions really suck as do most Lippert components instructions. Way too many words that don't really seem to be coherent, seems like just a few words and some good quality pictures would be more helpful.
Great to deal with super fast shipping
They work effectively and easily to help stabilize our fifth wheel.
Took about 3 hours and two beers to install. As far as the instruction sheet, pretty sure if they tried they couldn't make the instructions more confusing. I just watched a couple videos. Did not take out 100 % of the movement, still quite satisfied with results. Would recommend
Missing a short stablizer. Who do I contact to get the missing arm
Love the stabilizers put on front and back of my 33 foot 5th wheel solid it up amazely. Deffintly would recommend them.Thank you etrailer best price and best quality.
The single best upgrade I’ve done to our fifth wheel. Installation took a few hours in my driveway. We camp as a family of four with a dog. Someone sneezing used to shake our trailer - now the stability is greatly improved with almost no shake. Adds a few minutes to setup time - but absolutely worth it.

One year in - still the best upgrade weve done to our Fifth Wheel. Product has held up well - no rust or functional issues, and works as well as the day I installed it. All good!
