Maybe it will be available on the 4x2. This is not what was explained to me but I will copy and paste an email that a friend received from Nissan...This sorta sounds like a yes for the 4x2. Nissan seems to have a new mystery answer daily.
This is his original message with his name omitted for privacy:
Gentlemen -
Your news release regarding the Nissan Titan mentions the
"Class-Exclusive Switch On Demand Electronically Controlled Locking Rear
Differential" will have "late availability". I am considering the
purchase of a new large pickup and have narrowed the choice between your
new Nissan Titan King Cab SE 4x2 and the 2004 Ford F-150 Supercab XLT
4x2.
When will the locking differential be made available for the SE two
wheel drive as an option? This is a major decision point for me and a
specific release date would make a decision favorable to the Titan much
more likely.
Thank you for your response.
This is Nissan's response:
