On a nbs truck (07 Silverado 4x4) can you fit 33x12.5 with just a levelin kit or do you need to go higher with a 4" lift?

 

I got on google and typed "NBS Chevy 33" and they all had a 4-inch lift. I did see one on gmtruck site, the guy said he had a 2.5" kit on his truck running 33s and only rubbed on sharp turns.

long link but it my help you

 

alright thanks man

 

i put a 2.5 leveling kit on my 08 1500 and i have 33 12.5 17 pro comp mud terrains on my stock rims and they dont rub, mines coil over though are the 07s coil over or still torsion bar?

 

I'm guessin they did away with the torsion bars because it doesn't have them like mine. It'd be the 2.5 in. spacer

 

Im running 285/70/17 BFG KM2'S on an 08 reg cab with a 2.5in lift in front and have no problem with them. no more torsion bars on nbst
