JT's Strong Arm Jack Stabilizer Kit for 5th Wheel RVs w/ Less Than 58" Between Landing Gear

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.1384486

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.1280803

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 recommend1111768

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.1357731

Absolutely makes a difference in stability. Before installing these the nose of coach would sway back and forth with the kids running around. Now, little to no movement. Installation was simple and took about 3 hours. Brackets are permanent and do not add any more time to when setting up trailer at site. Would recommend these over any other similar fixes.

For an even bigger footprint, add snap pads. Bro...1451349

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. 777228

As I have not used them yet but have installed them they were pretty easy to install. I have a 37 foot long travel trailer so I hope that when I use them they will stop all of the rocking in my Rv1107800

I have had the opportunity to put 5he strong arms to the test. And I have to say they work great and I had less movement in my RV. But you have to know how to use them to get full results. So this is how I have found out that works best. With you camper unhooked from vehicle level the camper front to back just with the tongue jack. Then let it down by counting to five. Then put your back jacks down snug and tighten strong arms. Then go back to tongue jack count to five and let it back up . Then put your front jacks down and tighten the strong arms . Then let some weight off of the tongue so the weight will be on the strong arms then you should be good.

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. 610966

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.909251

After using these over the camping season this year, I would say it was worth every penny. These stabilizers take all of the movement out of the camper. It is very noticeable that that camper no longer has any movement and makes sleeping a lot easier.

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. 778142

We love the j t strongarms. Our grey wolf 23mk would shake like crazy just walking in it and now it is rock solid. Worth every penny1306609

Review from a similar JT Strong Arm in Camper Jacks

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.559548

Overall they did help stabilzer my trailer. T-handles could use some help though. I relocated the two back ones from the top to the side and made for easier access and designed a wrench/pipe to tighten and loosen them.1284825

After owning campers that only had scissor jacks these were a awesome addition to our camper. We have kids and a 98# labrador dog that shook the whole camper. Installed these and the shake was 98% eliminated. I did rig up a temporary stabilizer to see if what they were saying was true before I bought them. My half ass attempt to copy the stabilizer to see if it would work, which it did work, convinced me to buy these and I would buy them again in a heartbeat.1258587

Review from a similar JT Strong Arm in Camper Jacks

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.826269

Still extremely pleased with these. Feels like a house on concrete foundation.

Review from a similar JT Strong Arm in Camper Jacks

First, let me say the service I received from etrailer was superb. Now that’s out of the way, the very mixed reviews on the JT’s Strong Arm product is very deserved. I have not gotten to use them yet so I am just commenting on the installation.

I’m not the best mechanic in the world but was trained by USAF as an auto mechanic at the end of the Vietnam conflict so I do have some experience. The directions are nearly useless, frankly. I would rather have had them tell me in general terms how they operate and let me figure it out on my own. Once I put away the instruction sheet they were easy to install.

One tip I’m glad I read in reviews, and not mentioned in the instructions, watch where your electrical and gas lines route along the inside (sometimes hidden) part of I-beams and C-channel. Yes, you should always do that when drilling, but when frustration from reading bad directions gets in the mix it’s even more important. That one tip saved me time, money and possibly injury.

The “self-tapping” bolts did not self-tap, either. I tried running them in by hand and with a cordless 1/4” impact. Both times the self-tapping just stripped threads off which meant I had to go buy more ny-lock nuts. I got a good education on how scissor jacks are made, too. Not from the instructions, but from a mistake I made putting in the swing bolts and letting the center piece of the jack “gearbox” come loose. That could come in handy in the future.

I also read that someone ruined a scissor jack trying to move the jack up or down with the Strong Arm T-handle tightened. I am capable of learning from other’s mistakes so I am putting 3/4” silicone vacuum hose caps over my jack so I can’t run them up or down without first checking the T-handle. That should be included in the kit IMHO. The T-handle should also have a tether since it does not have any kind of thread-lock to keep them from working loose as you drive down the road if you don’t re-tighten them in the stored/up position.

I will update my review when I have a chance to use them.802846

After one year and multiple uses of the JT Strong Arms I have to say the frustration from their poor installation documents may have been worth it. My trailer is rock solid now. Everything else I wrote stands and the caps I use on the jack has saved me from ruining jacks. The tethers to the T-handles have saved lost handles, too. Overall, they are a good addition to my trailer.

Nice package and an effective solution to a lot of the bounce when walking in the RV. Installed myself and pretty straight forward. You will need a good set of drill bits and a 3/8"-16 UNC tap depending on your scissor jack setup. Watched some install videos on them and decided they were right for me.1177340

Review from a similar JT Strong Arm in Camper Jacks

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.

Review from a similar JT Strong Arm in Camper Jacks

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!635011

Excellent, it’s like having a foundation under our camper. I’m so glad we added these to the camper. We love the camper but stability while camping was an issue. These should be a standard on all campers or highly recommended by a dealer. You will not be disappointed. However after the first camp outing you will ask yourself why you didn’t have these one the camper sooner. Happy Camping!
