I appreciate the advice but I don't think you read my post right, or at least I didn't make my point well. First, there is nothing car-like about the ride of any of the Nissan or Toyata trucks I've owned...at least not prior to about 1995. Second, its the F150 that rides more like car. And its made that way because that's what most F150 buyers want, even the one's who buy 4wd. It's great on the highway, sorry off-road. But I'll concede that the springs might be quite firm (it rarely bottoms out even when hopping along a trail). But that really isn't the issue. The problem is that they seem to be too lightly damped. If you recall from the original post, the issue that I'm having problems with is that once you hit a bump it just keeps on bouncing and bouncing. I don't mind the initial bounce. The continuous bouncing also dimishes control.
Removing the front anti-sway bar would greatly amplify the problem of 'sway'. The thing rocks like a dingy in a storm as it is. And I understand that shocks dampen oscillation. But they will dampen any oscillation, even if it is from the truck rocking side to side. So better shocks will surely help.
Of all the options I think either the Bilsteins or the Ranchos look best to me.
When I wasting money on hopping up my Nissan years ago, someone made firm polyurethane (or something) bushings to replace the rubber ones on the front anti-sway bar (and shocks). It seemed to help but it was probably my imagination (kind of like when your truck seems to run better after you wash it.) ;-)
But just to make it clear, I'm looking for firm _and_ responsive, which is what I consider a 'real' truck. I'm trying to get away from wallowing and unending bounce.
