Hi, I've got a stock 1993 SWB and I'm looking for a solid 2" lift for my rig. I don't drive it every day but it is my street rig too. I will wheel it a little here and there but mainly road, snow (CO). I want just enough lift for 31"s or 32"s without any unnecessary mods as economical as possible. Do I only need springs and shocks? Medium duty enough? OME or Terrafirma?
