Surfknack, just so you know, I am helping my buddy get a 5.5" Fabtech lift on his 98 Ranger. I have priced everything out for him, and here's my advice for you:
1: Call Fabtech and get all the part numbers you will need. That way when you order your kit or ask for prices you can make sure they are pricing everything you want, nothing more, nothing less. My buddy is just using his on road, no offroading, so we are just going with their rear blocks. You may want to go with springs or a shackle flip for the rear since your truck actually has some power and is going to be taller with bigger tires than his little Ranger.

, 800-874-2112, had the best prices for his Fabtech kit out of all the 4x4 advertisers in Four Wheeler and 4Wheel & Offroad. I dunno how it would be for your Chevy kit, but they beat the others by $100-400. Worth a look.
