Which shocks stop the body roll?

The Super Seer Motion Control Valves may e the same thing as this. They fit in the air line between the left and right air bags front and rear. They stop the air from rushing from the high side to the low side air bag on corners, trucks passing etc. They restrict the air flow. I had a Person that worked for one of the Shock Mfgs tell me tht was a better solution than larger sway bars. Seems Freightliner made some lighter chassis for Fleetwood and others a few years. The larger bars weren't the best solution as they worked the chassis too much.
