That's just a link to your own post, making the same assumptions..... And when has ford documentation not been trash? There is enough information on this forum to prove that's not the case, and people in this exact thread have already installed the updated 18 struts on non-18 cars but you just keep going back to the same wrong info. So I'm done arguing.@Biznatch Stock controller does have more than 2 signals to the stocks though there are only 2 modes. Unless the documentation from Ford is trash.
And I'm not saying they did make a big change to the shock, but that they could have done that and it would have made sense since at one point it appears as though they were developing for magnetic shocks. If they are showing the 2018 shock is not a replacement option for the 2016-2017 I would want more research into why Ford says that, not a they physically fit and all will be good with no/incomplete research reply.
*edit* Here's a direct link to the post on the DSC thread by DSC themselves, who have done far more extensive testing on the RS suspension than any of us.....
