I installed the restrictors several years ago. They work as advertised and I would make the same purchase again. I like how the coach no longer leans on Interstate curves/entrances and exits. The do help with the "Walmart wobble". They do not eliminate it but do help minimize it. Once installed, the coach feels more like a car. There is the initial movement, but that is it. No back and forth.
I installed the restrictors myself. For me, it required two trips under the coach. The first trip was to determine the diameter of the air lines. The front are different than the rear. The second was to do the install.
