I've been searching a lot on google as well as the forum here and cant seem to find a definitive answer. after a 2'' spacer lift, id like to get my '99 DII non SLS to sit level. Im not a fan of the front end slouch look. I've heard of DI front springs on a DII to level it out as well as taking DII rear springs and putting them in the front to level it. I am wondering if either of these are tried and confirmed methods of leveling the vehicle out. Any help is greatly appreciated!

 

You should only use spacers along with new coils, not old ones and certainly do not throw rear coils to the front and then have to figure what to do to level the truck out.
Buy a good medium or HD set of coils along with matching shock, depending on the type of wheeling you do, to set your height properly.
At this point your current coils are shot as are your shocks if they are original.
