I have a 2011 4 door Silverado 2WD and i currently have a Rough Country 2 inch Leveling block that goes under the front shocks. On the 2wd trucks the 2 inch doesn't seem to get the truck quite level. I was wondering if it would be safe to simply add another bolt under the block or above it to add a little more height to the front of the truck? also would i have to get my tires aligned after doing it??

Call topguncustomz and the 1/2" levelin kit from them. It's like 25 bucks shipped. I wouldn't try to put bolts in to lift it up.
