There are about 80 million high CG Sport Utility Vehicles (SUV) and Pickup trucks registered for use on the USA highways today. These vehicles are mostly equipped with traditional Leaf or Coil spring suspension systems that have not basically changed in application methods for decades. The recent introduction of computer control for yaw and pitch and speed through interaction with the Anti-lock Braking System (ABS) has made contemporary SUV's safer. But millions of existing vehicles suspension systems have now become seriously outdated. Opposing springs suspension stabilization is a new Patented method intended to reduce vehicle rollover propensity and improve stability. It works by controlling suspension rebound travel, utilizing the vehicle un-sprung weight as a counterweight to minimize the initial roll of the body during cornering or evasive maneuvers.

For years racecar designers and automotive suspension engineers have sought to keep the un-sprung wheel/axle component weight of a vehicle suspension and axle system to a minimum. In the early days, ultra light Magnesium wheels were considered a big break through. In the mean time, because we strived so hard to reduce un-sprung weight, we tended to consider it simply as an “Enemy” that had to be dealt with. So it may be a little surprising that un-sprung mass could actually become useful in controlling dynamic roll or pitch, but it can. Tire footprint stability and body roll recovery during negotiation of “S” bends and chicanes in racing are the key to faster times through these turns.
