Does the 2015 GMC Sierra have a locking differential?
Yes, the 2015 GMC Sierra does have a locking differential as an optional feature on certain models and trim levels. A locking differential provides improved traction in low-traction conditions, such as mud, snow, or gravel, by allowing both wheels on an axle to turn at the same speed. This is useful for off-road driving and for towing heavy loads. If you plan on using your 2015 GMC Sierra for off-roading or heavy-duty towing, it may be worth considering a model with a locking differential for improved traction and stability.
