First off why? The truck will end up standing taller in the front than the rear. And yes a spancer kit will go in above the longer spring that was installed for the lift.

if u put a 2" leveling spacer on top of the spring, your track bar will be a lil short and your axle will be more towards the driver side rather than perfectly centered. and your control arms will bring your axle back causing your tires to be closer to the back of your wheel well and more likely to rub... i went through it with my fabtec 6", i got a new adjustable trac bar and got pure performance long arms. i run 38s without issues and when i was bored my buddy n me traded for a week an i ran 40s with no issues of rubbing also.
