I just bought a 1989 F350SD regular cab Dually and I have a friend that has a 1989 F350 regular cab Dually that is not Super Duty and the suspension seems firmer on my truck. What are the main differences between F350Super Duty and regular F350. Any links to information on this would be muchly appreicated.

Thanks
Rob

 

The main difference is the springs and shocks, as the SD has a bit more carrying/towing capacity than the non-SD trucks of that vintage.
