I put these on my 2003 F350 with a 10 inch lift, the difference is night and day from the Pro Comps that were on it when I bought the truck. Before putting the Bilsteins on, the ride was ""squishy"" and unstable, now it feels like a whole new truck. Granted my truck has leaf spring suspension, so I wasn't expecting a miracle but I couldn't be happier with the way she rides now! Also, Bilstein's customer service is amazing, I called to find out what shock I needed for my lift and they gave me the part number in less than a minute. If you are questioning wether or not this shock is for you, don't hesistate to give it a shot, I think you will be pleasantly surprised.
