Hey man I think there might be something specific to how you set up the bars, because myself, and one other member here when it goes up or down my pinion angle does not change... my upper bars are more towards the front then the rear, maybe thats the trick, I dunno... i bought my 4 link set up from cando, and just mocked it up, tacked it all, and finally found something that seems to work... also I get CRAZY lift outta the rear...
