The primary function is to allow the rear wheels to rotate at different speeds during turns, preventing tire scrubbing and improving handling.
Typical torque capacity ranges from 1500 to 3000 N·m, but the exact value depends on the vehicle model and application.
The axle ratio (3.0–4.5:1) determines the final drive ratio, affecting acceleration and fuel economy.
Always confirm model-specific values and standards with the legal manufacturer or supplier, as listed values are reference ranges.
