4 way manual management. Still the most reliable system on the market for daily driving IMHO, May not be the most accurate for ride height adjustment but. I have no digital computerized controllers or manifolds that can go bad on me. The only electronics are the Compressor, 12v40a relay, and the pressure switch. Hmm I might have to look into the jeep shocks for the rear, I know a buddy and fellow member here who is also bagged runs SLK struts up front on his 202 its a 4 banger though. I got the heavy v8 up there so not to sure i can get away with SLK struts up front.
