I want to do a 4 inch lift on my 04, and I went to the truck place and they suggested skyjacker, but looking at the catalog there were only parts listed for an F250.

My questions are:
1. Would a lift turn my truck into an F250 with F350 badges? I don't want to screw it up.
2. There was one kit that used Blocks, and the other I had to get rear springs. My truck already has blocks in the rear, and I don't want the truck to look like its leaning backwards. Does the spring kit look better? Which one would people recommend? I'm not doing it to go off road, just looks and snow.

Thanks in advance.
