What are the advantages and disadvantages of differential lock?

Differential locks enhance traction by ensuring that both wheels on an axle rotate at the same speed, which is particularly beneficial in off-road or slippery conditions. This improved traction can prevent wheel spin and increase stability when navigating challenging terrains. However, a disadvantage is that using a differential lock on hard surfaces can lead to tire wear, handling difficulties, and potential damage to the drivetrain, as it can cause binding and stress on the vehicle during turns. Additionally, not all drivers may be familiar with how or when to effectively use this feature.
