Summo Springs are Super!!! on my E450 Shuttle Van
2005 Ford E450 6.0 Diesel; 15 passenger shuttle van that has a wheel chair lift. I also installed the front springs. Since I'm not carrying anywhere near the payload of 15 passengers, the van/bus rides hard. It now rides an easy 60-75% better; road sway and even straight road travel due to irregular pavement resulted in less hard thumps. I also updated the OE shocks to Blistein HD.
Replaced stock coils and 2" lift with a set of 2.5" over supercoils on my 2004 Dodge 3500. They raised the truck another inch, that tells how much the stocks were sagging. I also installed Spohn dual shock towers. All this gave me what I was looking for. A little stiff empty but I'm rarely that. Even through the holidays Auto Anything delivered a great product quickly.
