Improving Towing Capability with Hellwig and Bilstein Part One


This pressure valve controls the on and off for the pump and maintains a minimal pressure in the tank if you leave the power switch on.  This makes it so the air system is ready to go all the time with no waiting. This is perfect for long trips and varying loads. 
We hooked the power to a constant source in the fuse box. 
Next, Howard ran the wires to the switch relay and the air lines to the center console where we could hide the controls. 
Howard mounted the power switch to the air pressure panel so all controls could be easily accessed. What a clean installation! 
The air lines were run from the control panel, to the air bags and then to the air tank.
