My son and I just put new springs on my F-250. It's a 1996 with 420,000 miles. It sagged a bit and was at times a bit like a tuna boat with the camper on and my bass boat hooked up. Stock springs were a 4/1 pack. I bought 6/1 packs from SD springs. Great upgrade. Now loaded the bed sits, height wise, where it was empty before. Handles the load great. Just did 4500 mile trip with camper and hardly knew it was there. Empty? Well, that's a kidney buster now. The shocks are Bilsteins that are 2 years old. Rough ride. Those trucks are just that, trucks, and will not ride like my Lincoln but this is rough now empty. Nice and smooth loaded. New springs on an older truck are a must in my mind. The difference was phenomenal. But smooth... No. Still very glad I did it.
