Fox recently updated their packaging and stickers for the 2.0s, but internally, they're the same shocks. As far as longevity, a lot of it depends on how you use your truck. After 80,000 miles on a truck with a heavy bumper with a good mix of on and off-road, the shocks could probably due with at least a rebuild. Whether you'd rather replace them entirely is up to you, though you may want to call local shops and see how much they'd charge for a rebuild before you make a decision to replace.
