I hate to sound like a "pot stirrer" here but for the life of me I can't understand how a king pin stabilizer can make any difference in the stability of a fiver. Your front-to-back stability is already provided by the front jacks and rear scissor jacks. Any device, such as the aforementioned king pin stabilizer can't have any possible effect on side-to-side movement, according to my way of thinking.
I know many of you folks swear by these devices and maybe they DO work but mathematically I don't see how. Explanations???

The stability provided by the front and rear jacks is not much.. especially since the fronts are not braced. My rear stabilizers were installed at a 45* angle which helps some. It's the Rotochocks that provide much of my front-to-back stability.
KPS are designed to help side-to-side movement, hence many of them are simply two legs. Without my BAL 3-leg kps, I can easily rock my 5er from side to side just by pushing on it. With the stabilizer, it's much more difficult to move.
The science of it I cannot fully explain, but they do help. If I wanted the BEST stabilizers, I'd get those metal arm braces that are bolted to your frame and connected to the coach's stabilizer legs.
