Yea 5:13s are a no go. Our front end not very big. If your going to stay with 37s for a long time Id go 4:56s. That will be plenty. 4:88s for 38s n up. My bud has a 6" with 37s. Rubs when doin extreme turns but not that bad. Do a spacer up front and a AAL in the rear. But of course if you have the extra money go with a body lift but than Id say go ahead and go for the full 11.5" like mine on some 38s or 40s!!

there is no correct ratio for a given tire size. when gearing for a lifted truck i like to have a slightly lower then stock final drive ratio just to compensate for the weight of the tires. i have 37s and 4.88s. my truck is 2wd so i could have done 5.13, sorry i didnt
