An Automatic Limited-Slip Differential (ALS) is a type of limited-slip differential (LSD) that automatically engages when needed. It works by applying pressure to the side gears of the differential, reducing the amount of wheel spin when one wheel encounters less traction than the other.
This allows for smoother and more efficient power delivery to the drive wheels and helps to improve handling and stability, particularly when cornering. ALS is found in many performance vehicles and is highly recommended for applications where traction control is required.
