When I bought my QX, I seen a few other ones around the same price. Maybe they have gone up?
The QX can have HBMC and non-HBMC. The HBMC suspension is actually what most of the Aussies run, but to be honest I dont know anything really about lifting them. The non-HBMC is just a normal coil spring suspension front and rear, with Air shocks in the rear. Air shocks can be removed without causing any dash lights or error codes.
If you could figure out how to get the offset alignment bushings for the rear, that would help some people. When lifting the rear, you can quickly run out of toe adjustment. In AUS, they have offset bushings available to fix this.
Also, I love Monteros. I think the 2nd Gen QX/Armada platform is pretty comparable, just more modern, more power, etc.
