JT Strong Arm Install (w/Electric Stabilizers) - Best RV Upgrade EVER!!!!!


The thing with rv's, fifth wheels, and travel trailers is that they do not come factory very stable. Trailers are notorious for rocking around on the narrow front landing gear and rear jacks, especially when the wind whips up. The JT strong arm system solve this problem by creating a triangle between the jacks and the solid trailer frame. Once installed and tightened up any side to side and front to back movement is substantially dampened.

Like a rock-solid race car chassis, JT's Strong Arm Jack Stabilizers use triangles β€” the strongest shape in nature β€” to eliminate unwanted chassis movement. One end of each stabilizer tube attaches to each landing gear leg and the other to the RV frame, forming a rigid triangle. There is no welding required and no need to remove and reattach during setup. It's permanent! When parked, JT's Strong Arm Jack Stabilizers telescope into place with the jacks.


If you decide to do the installation yourself, expect to spend several hours. It's not overly complicated, but there is quite the assortment of hardware to install and attach. You'll need a decent power drill and some quality metal bits to bore mounting holes in the steel trailer frame.

I found the included paper manual hard to follow with low-quality pictures but did find this terrific in-depth instructional video on the LCI Store.

The install on my Keystone Premier Travel Trailer went well, and I got it done in an afternoon. For the front electric stabilizers, I drilled a hole in the jack pad to attach the front to back stabilizer and installed a 2" steel channel across to the other jack for the side to side stabilizer.

The rear stabilizers were quite a bit easier. We just used the supplied i-bolt and drilled into the rear frame for the mounting blocks.



Once everything was bolted in place and adjusted, we gave the JT's Strong Arm system a try and are more than happy with the results. Movement is significantly reduced!

Pros:
Excellent quality, long-lasting hardware
Reduces movement and shaking inside the RV
More stability in high winds
Stays attached to the RV (one time install)
Easy to adjust bars and T-handles
Transferable to new RV
Cons:
Adds about 40 lbs to the rig weight
More hardware to inspect and maintain
Extra setup and breakdown time
Paper instructions hard to follow and small pictures
Lose a notch on the front landing gear height
