Hey Mike, thanks for the update! That's really refreshing to hear.

As far as the front is concerned, using a large spacer on top of the stock strut is adequate and is common for most "basic" suspension lifts for other vehicles. I personally (as well as most people in the truck market) like to upgrade our shocks/struts when we install suspension lifts. Most lift companies (including superlift for some of the other vehicles) have the option of an upgraded strut, usually made by Bilstein, that eliminates the need for the spacer.

For example, straight from superlifts website for the GM 2007+ 1500 4x4 pickups:
Superlift’s other lift method replaces the factory strut bodies with lifetime-warranted premium gas struts. These new struts have the same features as our 2.5½ struts (discussed on previous page).
I think it's a bit redundant that I'd have to purchase new OEM spec struts and install a spacer on those. It's a much cleaner setup to just install a longer strut (which is very common) and it also allows us to have matching front/rear dampers.
