Tune your power steering with our new Adjustable Power Steering Valve. It allows you to set, or ‘tune’, the ‘feel’ of your power steering with just the turn of a knob. The high pressure steering fluid goes thru the lower high pressure passage to the rack and back thru the upper low pressure line to the reservoir. As the knob is turned counter-clockwise, the needle valve is raised up which allows the high pressure fluid to bleed off into the return line, which reduces pressure to the rack and pinion to tighten the feel of the steering. You can go from full power to almost full manual with just the turn of the knob!
