I have a 2004 Silverado Z71, and I am thinking about putting a 6" suspension lift along with a leveling kit. My question is, do you think 37" Nitto's will fit under it after doing a little trimming off the fenders?

should cause my dads only has a 3" body lift on his 2003 GMC 2500HD a he runs 35 mud terrains with the front bumper trimmed a little bit

 

It depends on what wheels you would use. What are you going to go with?

 

Im going with 18" black american eagle 197's

 

How wide? What backspacing?

 

18x9..

 

I dont think you would be able to fit them maybe get a 2" body lift
