    Well I’m runnin 10 inches of lift on my 81 K30 and my front pinion angle is f**ked. I’m just trying to figure out the easiest way to point my pinion at my t case. Keep in mind the spring perch is machined on the diff.

    P.S. my knuckles will be adjusted to fix the caster.

    Well the right way is not the easiest. I use shims right now, IMHO this is not the right way.

    You need to figure out where the perch needs to be anglewise and then take it to a machine shop, fill the holes, machine the angle into it then redrill and tap the holes, of course the other side is easier just cut off the perch and reweld at the correct angle

    This post interests me in a very big way. I have a Superlift 10" Suspension Lift waiting in the wings for installation. I am rebuilding my D60 and the springs have shims attached. So what kind of difficulty am I going to run into. As far as I know the shims did/do the trick. No?

    Dynatrac offers a solution, but it isn't cheap. Ship them a bare low pinion housing and they'll replace the center section with a custom high pinion housing and ship it back. Last I knew it cost $900 plus the shipping. :yikes:

    I had those superlift 10" springs a while back and they SUCK A$$. You'll be lucky to get an inch of suspension travel. Just about any leaf springs that is bigger than 6" of lift has too much arc and are way too stiff.
    What I did to achieve 10" of lift was dropped my front spring hanger down 4", extended my shackles 4", and used a set of BDS 6" springs, now the difference is night and day.

    good for 8 inchs

    the rear is reverse shackel, longer shackel, and 64s with add a lift..
