If those Alcoa wheels are factory you probably have 5.5” back spacing? If so you may want to add 1” wheel spacers along with the lift to space those 33’s out a smidgen. Also the plan to do the motor mount lift is a good one in conjunction with the suspension and body lift. It will help with your driveline angle so you will not have to do an expensive SYE mod to your Transfer case or install a T-case lowering kit to eliminate driveline vibration. At 3” lift you may experience a small amount of vibration from your driveshaft after the lift but the 1” MM lift will head this problem off.
