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.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
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. 438529
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!! 542386
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
Chris H - 03/12/2020The product is awesome, lots of great hardware and installation options. Thanks for keeping the cost down by offering optional mounting styles to those that need them vs putting them in every kit. Installation directions are worse than most offshore furniture assembly directions. I was missing one of the smaller diameter tubes in my box and etrailer got this taken care of very rapidly! The stability improvement to my 5th wheel is simply amazing! 910154
Installation was a breeze with the included directions. I had to modify one side due to generator exhaust. 875720
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
All that we expected on this product. Quick delivery!! Thank you 808068
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
The JT strong Arms perform great they really take the shake and wobble out of my fifth wheel 774737
Stabilize my 5th wheel very well. Takes alot of the rockin out, unless you want it to rock. Lol I have 6 point hydraulic auto levelers and u have to get lug adapters, they don't tell u to paint them so they rusted bad. Paint before installing. 723361
Good quality product. The install was fairly easy. It did a nice job of tightening up my fifth wheel. A year later, they still look and work like new. 705144
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. 682452
Made a huge difference in stability. Used properly JT Strong Arms almost eliminated the movement in my 5th wheel. 669743
Mike M - 07/14/2020Great 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. 663693
James H - 06/28/2020Strong arm stabilizers are best invention. I have a 37 foot Voltage and these help take all the motion out of the trailer when moving around in it. I would highly recommend. 662750
Great product! These stabilizers worked great, somewhat easy install. Hardest part is finding the right place to secure the mounting brackets in the front. They make all the difference when you have them tight; then the movement of the 5th wheel is gone. Matt 609666
I had to replace entire unit due to my error of raising jack too far. My issues with the JTs is this. Should have RED line to mark the don’t raise higher than point. Also if you damage one you have to buy a set as don’t sell separate. That’s jacked. 577752
Super satisfied with etrailer.com. Ordered a set of JT Strong Arm Stabilizers for my trailer on a Wednesday. Free shipping in 3-5 business days was the eta on delivery. I got it in 2 days! Great customer service and they keep you informed on when your package ships from the warehouse. They will receive my bussiness again in the future. 576568
An excellent product which stabilizes the fifthwheel on quite angles, outstanding service on behalf of Etrailer, I was very satisfied. Thank you Etrailer 572038
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. 568782
John - 09/26/2019Was checking out website, on a Sunday. Could not believe they had a sales person there and answered all my questions. Hung up and placed order! Was shocked when order arrived THURSDAY the same week!’ GREAT business!! 561612
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
I love the product. Although this is the second one. The first one that came was an empty box!!?? I reordered and the 2nd one was sent right out. Good customer service. 549791
