It only.took 4+ years and 2 commanders, I finally ordered my superlift.
I will have a full OME hd kit with top mount and all for sale soon, the kit barely has 6k miles on it.
You went through 2 Commanders in 4 years???
I hope for your sake they (Superlift) send you the proper EGR (Electronic Geometry Recalibration) module with your Superlift kit.
When I ordered mine, for some reason the EGR module was sent separately from the rest of the kit and arrived a few days behind everything else - when it finally arrived, it was the wrong one. They had had sent me one for an 06/07 Commander which was not the correct module for my 08, I needed an EGR module for an 08-10 model; they did send the correct one FED-EX overnight when they were informed of their mistake.
It was still quite annoying to deal with none the less.
