Iam gettin a 3inch front leveling kit and a 1 inch rear to keep the truck leveled or slightly higher in the the back end. Will this set up work?? Or will it look like iam carrying a load? (Lowered rear end)! Thanks in advance!!!

 

The best way to tell would be to park on a level surface and measure from the ground to the top of the wheel opening in the fender on all four wheels and add in the 3" on the front and 1" on the back.

 

I wouldn't get a 3 inch because of the stress it will put your ball joins under. I have just a 2 inch level and they're already at an odd angle so I can't imagine another inch.
If I were you I'd go with either a 2 or 2.5 inch leveling kit with an AAL (add a leaf) for 1 inch in the rear. Good luck!
