WOOHOO! Post #200!
welcome to the board.
and the cheapest way to get 4-5 inches on a first gen is F150 coil seats for the front, extended shackles for the back, and a 3" body lift. I got my coil seats from a junkyard for $5. The best shackles, i'm told, are warrior shackles (about $60), and a Performance Accessories 3" body lift will run you right around $100.
Here is TBARS' write for coil seats and shackles...

Look on
www.4wheelparts.com for body lift for your truck - they sell the performance accessories.
And just search on here for "body lift". Hope this helps you out.
This will be your new best friend!
