Quadrasteer

Quadrasteer is the name of a four wheel steering system developed by Delphi Automotive while under the ownership of General Motors for use in automobiles.

It was available as an option on GM's full-size pickup trucks and 2500 Suburbans for model years 2002 through 2005.

The cost was lowered to $5,600, $2,000 and eventually $1,000 in order to boost sales.

The steering system was popular for applications frequently towing boats, fifth wheels, or other large equipment.

At higher speeds the system will turn the rear wheels slightly in the direction of the front wheels so as to increase stability and control.
