On the desk today today we have the new ATB Locker. Automatic Torque Biasing Limited Slip Differential. Say that fast 3 times. Some of the hi lights on this locker are.
Fully automatic, needs no driver input
Totally transparent on road, i.e, no unwanted adverse effects
Only comes into play when one wheel looses traction, i.e, a difference in wheel speed
Enhances the traction control as it multiplies the bias load created by the braking effect of the traction control
Needs no special oils
Needs no adjustment as the gears compensate for any wear that takes place
