Any luck on the shocks ? Wished I could find a rebuild kit since they are leaking from factory. Or find better stiffer shocks for that matter. Going to put 80 weight in them, To bad I can't find a locked center diff either, noticed most of the power going to the front so much that the front diff housing seems to be leaking !?! I'm going to shim up the diffs and use 100k on both front and rear, 1 million on the center. Would love to hear of anymore improvements you have come across.
