Re: 6" Lift on a 1980 k20 HELP

Like Andrew said, 6" changes everything. 4" should be plenty for 35's with some minor fender trimming which is the route I would pursue. Looking at your driveshaft spline engagement will let you see if you can go a little higher. an ORD zero rate would get you almost another 1" for not much money and your driveshafts should work.
