Z71 Suspension vs Regular by Part:

Differential

"The Z71 suspension includes an automatic locking rear differential which solves the problem presented by the open differential used in the regular suspension. The automatic locking rear differential uses a mechanism that locks the rotation of one wheel corresponding to the other.

No matter how little or how much traction the wheels have, there will be sync in the rotation of wheels. The automatic locking differential improves the distribution of drive shaft power. All Z71 have the automatic locking rear differentials as standard.

While the regular suspension uses an open differential, once the 4H mode is manually engaged and the center differential is closed in the open differentials, the power goes to 2 driveshafts evenly in both front and rear differentials. In this manual differential, you need to close the front or rear differential by a switch to close it.

Other than the locking differentials, some vehicles also use limited-slip differential (LSD), limiting the dependability of right and left axles. Pre-load spring-based and clutch-pack based are the two most common LSD technologies. These technologies allow the wheels to work normally on high traction and tarmac surfaces without the need of engaging or disengaging like the locking differentials."
