[QUOTE="OuchThatHurt, post: 1373846, member: 534"] .. so if this helps at all.... my 2012 ccsb has the same 47~ mph hopp. It did it completely stock, and now does it with 3" lift, and 3 sets of wheels and tires later. The only thing that helps it is 450ish + lbs of weight in the bed, or 450ish + tongue weight from a trailer. Even then it , feels to me, it is just dampened or hidden a bit. I've been under 5 different super duty's. X2 2011, x2 2012 and x1 2014. The only difference I can see is that my crossmember/transmission rubber mount is considerably more weak than theirs. Not sure if this is it, but it's at ford now getting a new one under warranty. Maybe this will fix it. If not, I have a set of 8ft traction bars being built now that are going to mount up about a foot behind my radius arm brackets. Stand by. [/QUOTE]
