Even on my budget SAS, the additional capability and durability make the expense WELL worth it. If you're the occassional wheeler who never hits truly hard trails then don't waste your money. I totally see the merits in SASing a late model nice truck vs. and old worn out piece of shit. Go drive an open sammy or CJ5 across country to a wheeling event and that should become very evident.

The X with this kit will drive better on road than any of the vehicles mentioned drive completely unmodified.
