    I have an 86 peterbilt 349 single axle (about 170 inch wheelbase ) that rides really rough. I know the shocks are probably shot. Can anyone tell me if there is something I can do to improve the ride besides new shocks? My father in law has a single axle cab over frightliner with about the same wheel base and it rides pretty nice. Thanks

    That, and how is the cab mounted?

    If the cab is rigid mounted, that alone will make a truck a beater.

    It has the air Trac rear end. Is that the problem? What suspension would you recommend?

    Air ride suspension AND an air ride cab, and you're still dealing with a rough ride?

    Hmmm... I'd say start with replacing the shocks.
