Stabilizing jacks don't really stabilize much at all

I have tried the X chocks and they are nothing but a tire chock, meant to prevent the tires from moving. They do nothing to stabilize a trailer from movement as they don’t do anything to minimize trailer suspension movement. I agree if you are looking to make the trailer solid, you need to get the frame suspended. The JT Strongarms do a great job stabilizing the trailer as it creates 6 points of contact with the 4 jacks on the trailer. I feel little to no movement in my trailer.
