I need some advice

[irishfogarty]

I am a college student and do not have too much money. I have a 95 gmc sierra ext cab,4X4, 6ft bed, 5.7 v8, no rust no probs that just has a redylift leveling kit. As most of you know Gmc's sit so low stock and even with a 2 in redylift, my buddies stock fords tower over mine. I would like to lift my truck about 6 inches but cant afford 1 grand for a suspension lift. I was thinking 3in blocks and addaleaf's.
If anyone could post links on good products that would work and keep my budget goal of 400-500$ it would be much appreciated.
Or even some opinions on what I should do would be a great help.
