Hydrosteer was the name given by George Kent Ltd and Cam Gears Limited through Hydrosteer Limited[1] of Luton, England, to its automotive power steering system. Initially Hydrosteer manufactured the Ross-Link system for commercial vehicles from 1953 under licence from Ross Gear and Tool of U.S.A.[2] Their own product available from 1961 was based on a cam and peg system and was characterised by its fully integrated design and variable steering ratio. This configuration provided automotive manufacturers with a fairly simple design modification to provide a power steering option for cars fitted with a conventional cam and peg steering box. It was fitted to several, mainly British, luxury automobiles of the era. Production continued up to 1973, with just over 105,000 units being produced. As a "first generation" assistance system, applications were somewhat varied in their tuning of the many system dynamics to the specific vehicle. The system fell out of use as powered rack and pinion steering systems gained in popularity.
The 1960s Hydrosteer system should not be confused with Hydrosteer Pty Ltd, an Australian company established in 1981 as a provider of heavy truck steering technology in that country.
