I have an 86' K-5, and I'm tired of my pussy half ton axles. I am thinking of getting a Dana 60 front, and a GM corporate 14 bolt rear. I am planning on making my Blazer into a mean indistrucktable off-road machine. I was just wondering if those big axles are the way to go, because I have been watching the Trucks T.V. marathon, and he is using a lot of Dana 44 fronts, and Dana 60 rears, or 9 inch rears. I guess all I want to know is will those axles work good for some heavy duty off-road abuse?
