Yeah 3" superlift springs and 2" shackle lift in the front is way too much for the driveline length.. I can see the splines and there is alot fo slop side to side play.. The axle was at full drop on both sides just hanging basically so if it articulates and the passenger side drops even more the driveline will probably slip right out.. So I am not messing around with this silly stage 1 stage 2 stuff and I am just going to mount rears up front and my chevys in the rear.. I will have a square driveline made since I still weld like crap but I am thinking I will try to get my duals at the same time. Any questions, comments, concerns, or advice?? This is my first real build so Im trying to build as I wheel and get money..
