I've got an '02 B4000 4x4 and I just want to do a very slight lift.

Reading on some other forums, I can crank the torsions bars up to 2" before the CV joints begin to bind, but I'm curious about the rear. I have some 2 and 3" blocks which I used to lower my old Mazda, yet I see on this truck, with the leafs being above the axle, there is already what looks like a 2 or 3" block in place.

What's the easiest route to go about raising the rear about 2 or 3" more?

I'm a n00b when it comes to lifting. Now I know why I always drive lowered trucks.... I'm having trouble getting it up.
