The Titan does not have a limited slip rear end (they're open diffs). It has ABLS (Active Brake Limited Slip) which actually works better than any LSD Nissans come out with. What this does is it uses the trucks ABS brake sensors to detect wheelspin. When one wheel slips, the ABS sensor tells the system to apply brakes to that wheel only. While that wheel is being slowed, power is automatically sent to the opposite wheel. It works great. But the nice thing about it is.....on 4X4 models, this system applys to both FRONT and REAR differentials! So in effect, you have Active Brake Limited Slip front and rear Dana axles!
