Old setup was ****. Too much to explain so if you feel like it, all the info can be found at AccuAir Suspension. Exactly right Luke, 3 height settings. 1 being cruising height, so I can roll in to a meet at the lowest driveable height 2 is normal driving height 3 is full lift to clear them huge Westfield speed humps and the double arrows is pancake mode Control now lets me lower the bags Front / Rear Side / Side Individual corners All 4 at once Old system only let me go front / rear. Aaaaand the cost. A nice $3000 including install. Btw Luke if you want my old control box to see what you can do with feel free.
