I just put Bilstein Heavy Duties from on my 2012 F250 SD 2wd yesterday. Truck has 48k miles. Both fronts were shot and one rear was getting there. What a difference! The ride is noticeably better.
I didn't notice until the last minute that the steering dampener was 10 inches too short. Fortunately I was able to get the stock dampener back on. The place I ordered from referred me to Bilstein tech support, of course. The Bilstein tech support guy refused to believe that my 31" dampener was stock, which it actually is.
