lowering a 1990 F-150

I've got a crappy f-150 work truck that needs to be lowered. What is a cheap way to lower it and what all do I need? A 2/4 drop is plenty for me to keep using it as a work truck. The truck is maybe worth about $1,500 and it's my daily driver so I don't want to spend to much on it. It's a long bed if that makes any difference?

I've wanted to do it for awhile and after I saw it yesterday with a flat tire I really liked it sitting low

bump

Springs and a flip kit Or drop I beams and flip kit...

i have I-beam air ride brackets for sale for $80 bucks or i will trade for s-10 cups for the 1st gen s-10's

yea i would use springs, you mite could swap in some ranger springs(ill measure some stockers for ya if ya want me to) and a flip kit.
