they made a design change a good while back on the 2708's I think the old design is where the negative reviews stemmed from. I have had the 2708's on for 50,000 miles now with no problems
the new design is partially re-manufactured the whole top piece is different, the "bag" will wear out eventually that is the weak point oem or not, replacements won't cost me anything.
* you may want to order or get a air line set, I did find that the drivers side line will be stretched beyond it's length if the shock is fully extended, my solution was to install one of the longer pieces on the drivers side between the shock and "T" where the lines connect near the pump this gives it more than plenty of room, passenger side is not a problem.
and do not order the Dorman air line set I couldn't get the lines to come apart even though it looked like they should come apart it appeared to be a one piece design.
Does the connection point on the new shock design move when the suspension cycles?
