Minimize chassis movement in your fifth-wheel RV with this jack stabilizer kit. Attach the telescoping tubes to your jacks and position them in place to brace your trailer frame. Includes 4 stabilizers for use at front of camper and 2 for the rear.I think Lippert should make a third kit that contains the correct hardware for the hydraulic style leveling system. Instead you have to add $XXX worth of pieces to complete the install, while discarding the $XXX worth of stuff that you can’t use. That is a hidden cost.
The quality is good.
I expect it to control the shaking, once I finish the install.
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.
This was a great buy. Much more stabilization in our camper than before. We are very pleased with the product.
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!!
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.

Still working great after a year! Still not rusted or corroded.
Very pleased I made this purchase. It has totally changed the stability of our fifth wheel. Very easy to install and well made.
Made my 5th wheel toy hauler rock solid.
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.
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 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.

Still extremely pleased with these. Feels like a house on concrete foundation.
everything looks and feels well made and rugged. We will see how it all goes together tomorrow.
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.
This stopped 99 percent of all movement in our 5th wheel.
Does what it says.
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.

Great! Performs as advertised. Recommended upgrade.
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.

Still working great, and looking good.
Good product helped some but didn’t remove all the movement easy to install with common sense
Great product. Really helped to stabilize my fifth wheel toy hauler. Very little movement when moving around inside the unit. Much more solid. Installation took about 2-2.5 hrs for both front and back landing. Instructions a little confusing at first but when you figure them out it's real easy. Very satisfied with this product and would recommend it to anyone looking for a more solid feel to their RV when set up.

very happy and satisfied with them as I said earlier everything holds true very satisfied.
Made a huge difference in stability. Used properly JT Strong Arms almost eliminated the movement in my 5th wheel.

After a year of use im a happy camper.
Everything went well, my 2nd stableizer I've installed. I didn't fell as tired and sore after 15yrs ago.
Product installed easy and works great.
This is repeat purchase, as I previously installed a set on another trailer I owned. Installation takes a couple of hours for an old guy (LOL). The folks at etrailer like Melissa make the selection process smooth, along with any questions I had.

Product still working great, no issues with function or quality. Good design and quality hardware.
The JT Strong Arm kit is a well designed package for installing stabilizers on the front jacks of a 5th wheel. You will need additional hardware and probably need to fabricate an additional cross brace to install the stabilizers on the rear jacks. Installing just the front stabilizers makes a huge improvement in trailer movement making me wonder why the hardware for the rear is not sold as a separate kit which would reduce the price. The installation instructions provided with the package are poorly organized and written and make installation appear more difficult than it really is. On-line videos and other information are more helpful than the instructions with the kit. The kit was supposed to include 3/8"-16 flanged self tapping bolts incorporating cutting grooves. The actual bolts provided were plain bolts without cutting grooves. So after drilling the 5/16" tap drill size for 3/8"-16 bolts in the longitudinal I-beam I attempted to tap the holes. Unfortunately the starter tap broke in torsion on the first hole. Fortunately on my trailer there was access (very limited) to above the I-beam flange so I drilled 3/8" holes and used nuts instead of tapping the I-beam flange. If you choose this approach shift the spacer mount position outward away from the I-beam vertical member by the spacer mount material thickness so the nut does not bear on the corner radius. If you must tap the I-beam flange because there is no access above the flange to install a nut, consider increasing the hole size to be tapped by 1/64 (21/64) understanding this will slightly reduce the thread load capacity. But these threads are not highly loaded. Something to be careful of is the location of the gas line under the trailer. Whatever installation method is used be sure there will be adequate clearance for the stabilizer bar to the gas line when in the fully up position. Overall a very good kit that I would purchase again. You could fabricate the same kit yourself but the end result would probably not be as well constructed unless you have a machine shop.
As always... quality products ... fast delivery .. competitive prices.
We mounted the jt stabilizers on a 2018 forest river wildcat 37wb ... front drop legs. Very easy install not using instructions.

Very pleased with the product. Works as described.
I installed the struts as directed on the front of my 28ft 5th wheel toy hauler. I also, installed the remaining two struts to my two scissor jacks that are mounted to the frame in front of the front wheel. I'm not completely satisfied with the product. I still have a very noticeable shaking of the trailer when walking inside or climbing up the three steps into the trailer.
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...
