i have a 2002 dodge ram qc an was wondering if i installed new tortion keys and three inch blocks in the back if the truck would sit level and if id have to put new shocks on all the way around.

 

you need 2" in the front for it to sit level and yes you will need new shocks

so if you put 3" blocks in the back you will need a 5" lift in the front (to sit level)

(these are average numbers, every truck is a bit different i only needed 1 3/4" in the front)

 

Hm if it isn't level, and you add two inches in the front, then three more in the back. No that won't sit level and you will be stuck with even more of a rake. Just crank the torsion keys and you'll sit level. If you really want to add a 3" block in the rear you can crank the torsion keys and get a 3" lift spindle.
