Limited-Slip Rear Axle

Vehicles with a limited-slip rear axle can give more traction on snow, mud, ice, sand, or gravel. When traction is low, this feature allows the drive wheel with the most traction to move the vehicle.

The limited-slip rear axle also gives the driver enhanced control when cornering hard or completing a maneuver, such as a lane change.
