Looking at leveling my 2010 F350 Crew Cab 4x4 (Lariat). Been researching and seems that 2" spacers for the coil springs would be right. I picked up the Zone Offroad spacers for $100 and now was told I may need longer front shocks and maybe trackbar? Anyone that has done this, can you tell me from your experience what I really need? Also, I assume I will need to get front end alignment after install?
