For a 6" lift, you install lowering brakckets for the lower control arms, but since the upper arms stay in the stock location you also install a new longer spindle. Because the lower arm is now farther away from the upper coilover frame mount (know as the "coil bucket") you need either a spacer to mount between the top of your stock shock and the upper frame mount ( sucks, a bad design) or you install longer shocks.

Coilover shocks are shocks that have the coil spring intergrated with the shock it self. You can either purchase the Pro Comp longer shocks(many have...and some have regretted it) or you can go thru PRG Products and purchase a SwayAway (SAW)brand coilover shock custom tuned to Greg's spec's...

Does that help any?....
