There must be a Mopar lift for 2012, because from the Jeep website:
2012 Wrangler | Call of Duty<sup>®</sup>: MW3 Edition | Jeep
RAISE YOUR GAME
There's an available upfit for Call of Duty: MW3 Edition for those who want to take it to the next level. This dealer-installed Mopar Performance Parts kit includes: Warn® Winch, 2-inch Lift Kit
, and Classic 5-hole wheels in Black. The 2-inch Lift Kit rides like a normal Wrangler on-road, but gives articulation like a 4-lift off-road.
It's designed to work with the Electronic Stability Control and Brake Lock Differential and can accommodate up to 35-inch tires. Includes: springs, shocks, new track bar, steering stabilizer, sway bar links and all hardware.
I attached a chart of the 2007 - 2011 lift part numbers (2"). I'm waiting to see if the 2012 part numbers change.
If I had a 4 door (any trans), it would already have a lift. However, I am giving careful consideration to the driveshaft angles on my 2 door / auto.
