HST/TDZ Power Steering Kit
Bolt-on / easy to install
The HST/TDZ power steering system can be fitted to any LHD or RHD Series Land Rover. This bolt-on system will assists you when you need it most: parking and low speed maneuvering. It will not alter the steering geometry, behavior at speed nor the turning circle.
Easy to fit. No cutting, drilling or welding to the chassis. The system can be fitted in a couple of hours. Also, if required, it can be return back to the original steering system very quickly.
In case of hose breakage or engine stop / drop of the hydraulic pressure, the vehicle is NOT left without steering, instead it will continue to act as normal manual steering since the valves and cylinder will circulate the hydraulic oil without resistance through the system allowing the necessary steering movement.
You can see it as a system that belongs to the driver rather then to the vehicle, this means you can simply take it off and refit it when you change Land Rovers.
The force needed to operate the steering wheel is reduced to only a fraction of it's original value. This allows the driver to carry out difficult maneuvers which can occur in difficult terrain, or in heavy town traffic. The force of only 2 to 5 Kg on the steering wheel will produce 800 to 1500 Kg on the road wheels. The physical couple applied to the steering wheel is always proportional to that applied to the road wheels. As a result the vehicle will always be smooth, precise and safe
The ram is located at the end of the steering link and applies the force directly onto the road wheels. This means that the links between the steering wheel and ram cylinder, like steering box and steering relay + connected ball joints, are not subject to excessive wear or high forces and are therefore protected against premature wear.
The ram system will also act as a hydraulic stabilizer, absorbing the vibrations that get back from the road wheels to the steering wheel giving better control over the steering.
The normal self centering, while driving out of corners or bends, is not affected. This will maintain the tendency to recuperate to the original position.
In case of tire burst the system will instantaneously correct as it acts in the opposite direction of the turning tendency of the burst tire to the steering system.
