ok so I just installed my 2.5" leveling kit on my 05 screw with an 8 inch rize kit. It looks bad ***, but sits much higher than i thought it would. Its almost like the suspension didnt settle like i thought it would. My angles are kinda sever but i USE 4WD ONCE IN A BLUE MOON AND ONLY AT LOW SPEED. i SHOULD BE OK RIGHT???? Also i drove the truck down the street after the install and Im hearing a strange like zzzzzzzzzzzzzzzzz noise coming front my passenger side. I cannot pi point what this is. Has anyone had anything like this on their install??

 

I have a 3" spacer on mine... no problem w/ noises... as far as your CV angles, I wouldn't recommend anything over 2"... I about to get rid of my 3" LK and replace it w/ a 2". You should be fine tho if you're going slow, and since you only use it every now and then.
