IM putting a leveling kit on top of my 6 inch suspension and then bigger blocks....how hard is this installl and can me in a few buddies do it easily...its the hell bent steel leveling kit and goes on top of the coil i think so u dont new coil compressors. let me know

 

I installed my Autospring level kit by myself in a little over an hour so you and a few buddies should have no problems. I've heard good things about the HBS kit too though.

 

I installed my AS kit as well. It is a very straight forward install. Here is the link to the thread that shows you how to do it step by step with pictures. Then you can decide if you want to install it or let some one.

Write-up: Auto spring 2.5" Leveling Kit Install

 

The Bilstein 5100's would be better for your ProComp kit. Keeps you from stacking spacers and may net a better ride.

If you're dead set on the spacer, it's a breeze to install.

 

Are rear blocks just as easy?

 

What brand is that 8.5" lift you have? I've looked at your photo gallery before and for some reason I thought you already had a 6inch with a stacked 2.5" spacer and bigger rear block.
