Mine rides like an old caddy the swaying that it has doesn't bother me. I have both sets of overloads in mine front and rear. My rear springs were basically new so I would imagine it rides like a new truck does. I never have felt I needed a sway bar and I have had the truck to 80mph on the freeway driving for a few hours.

So I guess its drinking time. These 56s have the same bushings front and rear. My current setup both are different. I will place an order with ORD for the greasable bushings.
