Here freshly completed 2011 JK with a 2" BDS lift on 33×12.50×17 BFG All Terrain T/A K/O tires.
Here is a 2006 TJ with a 3" front and 2" rear BDS Lift kit on 33×12.50×15 BFG's. The front end saggs excessively with the winch, Warn bumper and fog light bar on the front so 3" springs are needed to level it out.
