At the top, there's a torsion bar which fits inside the input shaft. An assembled torsion bar and input shaft are at the bottom. The torsion bar helps to maintain a good road feel at high speeds. Different applications require custom tuning to achieve good low-speed steering torque juxtaposed with the need for good high-speed road feel. Howe can manipulate the diameter of the torsion bar to match the application.
