Do you tow or haul anything heavy on the regular? My suggestion is to leave it alone unless there is some legitimate need to raise the front end. The rake is there for a reason. If you put a load on the back, you do not want the nose of the truck pointed up as it sacrifices handling. Pickups are designed to be closer to level under loaded weight so that they can safely tow and haul more weight.
If you need more ground clearance, do it right. Don't take shortcuts on suspensions. Going back to towing; towing and lifting are inversely compatible. The more you lift, the worse it tows.
If you just can't stand that your truck has a rake, go ahead and spend your money making it look like you want it to look. But do consider that there may be downsides.
