agree..... probably the best info would come from the guys that rebuild all this stuff.. damn expensive Tasca list the front for 450 each, and rear for 550 or so each for 2010 still......
I already spoke to a few companies that rebuild the Gen 1 shocks and they said they wont be into rebuilding the gen 2 shocks for a few years as Ford will warranty the stock shocks and replace.
I have been looking into 17 shocks on a 13.
-A few Issues I have found, the 17 shock will not bolt in up front as the frame mounted spot will notwork with the 17 front shock
-The springs are rated for the lighter 17 model, so heavier rate springs would be needed on a gen 1
-Both front and rear shocks on the gen 2 are longer then a Gen 1 so you will not be in the optimal range of the bypass, and the zoning will be off. There is a thread already about this in the Gen 2 section.
