JT’s Strong Arm Jack Stabilizers

Every trailer I’ve ever owned has uncomfortably swayed whenever a stiff wind hit it or even when somebody was just moving about the inside. I found the best fix to virtually eliminate this sway is JT’s Strongarm Jack Stabilizers. For about $300 you get a set of heavy duty quality made telescoping stabilizers for the front and rear of your 5th wheel or Travel Trailer.  Perfect for the do-it-yourselfer, you can install the front and back in about 2 hours using a tape measure, a drill and a few wrenches. Just measure the correct distance, mark the hole and drill. All the rest is simple bolt on using the supplied hardware.

Once installed, setup is as simple as leveling your trailer as usual and then tightening the T-handles at each corner. The best part about this mod is you can really see the improvement by pushing on your trailer before and after tightening. I marked the two telescoping rods where they come together with a black sharpie. I then rocked the trailer by hand and measured the movement of the two lines. I was surprised to see the distance between the lines as much as 1″ at the rods and much much more near the top of the trailer. Next, tighten the T-handles and repeat and you will see practicably no movement at all. I was very impressed.

JT stabilizers are distributed by The Mobile Outfitters, a Lippert company, that  makes a myriad of other Trailer & RV products including; Suspension and Alignment, Leveling, Jacks, Security, Hitch, and Pinbox products.
