Suspension Control Upgrades

Hey Folks,

I was dragging blue out, yesterday, to prep for driving to our new property, and I realized that I do greatly like the look of the car completely slammed. I don't, however, like the lever that is used for adjusting suspension height. Has anyone ever replaced this mechanism? I'm thinking maybe try and find a panel with three buttons to wire up that connect to a little servo or mechanism that adjusts the height: one that drops it completely, one that sets it to drive height, and one that sets it to max height.

Those levers  (front and rear) dont just control height, it is also part of the suspension to control body roll and bumps. They are constantly changing as you drive.

The dash knob does control height, probably by changing system preasure. If you put a pressure regulator on that main line it might be able to lower overall system pressure, but at what ride quality I dont know.

If you built a tiny stepper motor screw link from the arm to the sway bar you could control it's length, and thus the height while keeping the rest of the system doing what it is suppose to do. A Raspberry Pi could control it.

I was referring to the dash knob, rather than the blocks themselves. The dash knob, as far as I can tell, connects to a box in the front of the car via wire. Adjusting that lets you adjust the overall ride height for the vehicle.

Are you talking about replacing the dash knob mechanism with a solenoid control of some kind?  If so, it could certainly be done, but why?  I'm not sure what problem that solves.  The valve that the knob controls only has 4 discreet positions (one isn't available with the knob):  normal, high, locked and pressure dump (need to detach the cable from the control valve).  It doesn't "adjust" the height, it changes it from normal to high.  Nothing in between.
