I have a 1999 F350 SD 4x4 crew cab dually diesel (actual manufacture date 12/98). I would like to install a 4" lift kit. This truck will continue to be used for heavy hauling. Looking for advice on a 4” lift kit, Traction bar, tires to go on existing rims (existing tires are 235/85/R16) or 17” rims with tire options. Any other advice would be appreciated.
