I have a 1998 dodge ram 1500 with a 4in lift on it. I'm wondering what parts I should start with to freshen up the underbody. I want it to look good. Maybe replacing some parts. Adding new ones. What can I use to shine up rusting parts. Any suggestions. Trying to turn an old truck like new, just don't know where to start with things. Also what would help with smoothing the ride a little. I know it's going to be bumpy. But right now it feels like my truck is a rock on wheels driving down the street.
