You stated essentially what I was saying earlier, personally it has to be an improvement in damping and rebound, but I wouldn't do it because I can't get the lift I want and because I could get the 6112 for a little less than that which is essentially the same unit. Of course both those are just my opinion on what I would do and want.
Most companies don't think it is worth the time and effort to put into redoing things even as simple as wording on the parts for a market that while it has been a major sales point for them, there are more standard F150s on the market than Tremors. What I stated about Ford said that it wouldn't be an improvement I think is because it doesn't give the height to the Tremor and I guess they feel the soft suspension that the Tremor comes with is more what people want it for and that going to this would stiffen it. Again they are avoiding liability issues. We are on the same page as to reasoning so many state will not work or not recommended. Good luck and please let us know what you hear if anything from them, because to date the only thing they have stated is it isn't an improvement and if they feel it isn't an improvement they won't recommend it.
