Automatic Locking Rear Differential
When rear-wheel slippage is detected at lower speeds, the locking differential mechanism locks the rear axle, sending maximum drive power to both rear wheels. Standard on LTZ and included on half-ton 2LT and 3LT models with the available Z71 Off-Road Package. Available on all other 2008 Suburban models.
Locking rear differential benefits include:
- Enhanced performance for on- and off-road driving and towing
- Full lockup for maximum drive power to both rear wheels
- Fully automatic engagement
- Speed-sensitive actuation, which provides axle lockup when one wheel spins faster than the other
