Ok, so I have an 08 Ltd With rear air suspension, but NO adjustable shocks. I took out the factory struts in the front, and rear shocks, and replaced with Bilstein 5100 struts in the front, and 5100 shocks in the back. Rides a bunch firmer than stock with less bounce. Set the struts on the 1.5" lift setting... One thing I noticed is that the trear sensors matched the front height, so I'm level all around. Was a nice surprise.
BUT I want to take the air suspension out and replace with thicker springs, and install an airlift system instead, to handle more weight, as we often tow a travel trailer with 7-8 passengers. So... Was wondering on the thread above, if there are any comments on how the swap worked out? Ride quality etc? Also, my main question is were there error messages on the dashboard after taking the hardware out?
