I just purchased this '07 1500 4x4. It rides pretty well for a big truck, but seams to transfer a lot of the winter bumps and pot holes into the cab. This is going to be the wife's primary vehicle to drive she's worried about the ride quality. I've attached a pic, I'm not sure if it has a front end lift or not. Would new shocks help? The truck has under 50k miles on it.
