Chrysler Corporation's Isolated Transverse Torsion Bar Front Suspension

To satisfy the objectives of Chrysler's new generation of compact vehicles, a unique front suspension system was created. This system has achieved an outstanding level of ride comfort while providing significant advantages in the basic vehicle packaging. The key to the system is the transverse torsion bar and bushings which serve the dual function of suspension spring and fore and aft restraint for the lower control arm. Producing this torsion bar in mass production required advances in both engineering and manufacturing technology.
