Question about and old Anti-Sway device

[artengn]

Some time in the late 70s, I ran across a device that was used by the Highway Patrol to counteract vehicle sway during cornering. It had a movable weight (approx. 200 lb.) that was enclosed in a (approx.) 4'x6"x6" box. It was intended to be mounted low on the body transversely across the vehicle's centerline. Centripetal force caused a hydraulic system to proportionally slide the weight from one end of the box to the other counteracting vehicle sway. It worked exceeding well and allowed a friend's pickup truck to stay [essentially] flat and stable on curves at speeds up to and during tire release. Does anyone here have information about that or similar devices?

Thank you. /r

Methods have changed, now active swaybars are quite common. Especially in vehicles which have to perform both offroad and onroad.

The landrover discovery Series 2 had this system and called it ACE (Active Cornering Enhancement). Someone in australia sold a similar system for retrofit which was activated by a pendulum valve. Such a system even works to flatten the vehicle on sideslopes.
