Had a few questions on these. They are from the 2.5" backcountry leveling system I had on my truck. These would be an upgrade to a leveled truck or commuter package. You'd need Carli front coils, trackbar, and brake line extensions in additional to these shocks to replicate the front of their backcountry system. Shocks are most expensive part, so adding these with a few other parts would get you a complete lift for cheaper.
Was about to post a link, but don't know if I can. Search Carli Super Duty Backcountry 2.0 leveling system for more details
