I have a 2005 2500 Cummins 4x4. I plan on putting a 6" susp lift and running 37x13.5 tires. My rims will be 17x9 and a slight neg off set. Will the lift be high enough? I have seen numerous trucks with this set up but I also see trucks with 8" for 37s. Some sites say you need 8". It will primarily be used on the street so I should be fine right? I wont be on the trail so I wont need articulation but I might throw it in the mud. Will I be ok?
