JT's by Lippert 191024 Strong Arm Jack RV Stabilizer

Fits 5th wheel with scissor or telescoping rear jacks under 58". A one time, permanent installation that virtually eliminates the unwanted chassis movement and eliminates the need for ineffective tripods. This patent pending universal system contains six stabilizer tubes in each kit: Four go on the front of the rig and two on the rear. It's a bolt-on kit, designed for the do-it-yourselfer. One end of each stabilizer tube attaches to a leveling jack and the other end to the RV frame, forming a rigid triangle. There's no welding required and no need to remove and reattach during set up. A unique system of custom designed and engineered hardware enables them to attach to and stabilize telescoping and scissors jacks. When parked, the stabilizers telescope into place with the jacks. Once the RV is leveled, twisting the "T" handles locks the system in place.
