What is a primary benefit of a limited slip differential?

A primary benefit of a limited slip differential is that it distributes power to the wheel with the most grip. This feature is particularly important when driving in conditions where traction is uneven, such as on slippery surfaces or off-road terrains. When one wheel begins to spin due to a lack of traction, the limited slip differential redirects power to the wheel that has better traction, which helps maintain control and improves acceleration.

This capability allows for better handling and stability, especially in adverse driving conditions. Unlike an open differential, which would allow all the power to go to the spinning wheel, the limited slip differential ensures that the vehicle maintains forward momentum and improves overall performance.

The other options do not describe functions or benefits typically associated with a limited slip differential. For example, while it does improve traction, it does not prevent any wheel from spinning or lock the axles together like a locking differential would. Additionally, the impact of a limited slip differential on fuel efficiency can be variable and isn't its primary purpose.
