A new XD120 Xtreme Duty power steering gear for heavy vocational trucks has been introduced by R.H. Sheppard Co. to replace its 592 series, which dates to 1968. The XD120, for 18,000- to 23,000-pound steer axles, has a high output torque 78,825 inch-pounds at 150 bar (2,175 psi) operating pressure. It can be used in single- or multi-gear/multi-axle applications, and is a drop-in replacement for the 592. The XD120 claims car-like road feel, superior on-center performance and quicker steering response with less driver effort. Production is planned for several new vehicle models in early 2007.
