Question

DIFFERENTIAL | LIMITED SLIP - What does a limited-slip differential (LSD) do?

Accepted Answer

The primary function of a limited slip differential (LSD) is to effectively distribute torque as needed. During regular driving conditions, a positraction LSD is engaged, ensuring equal traction is provided to both wheels. However, when the throttle is aggressively pressed, tight corners are taken, or when navigating through loose gravel trails, the LSD kicks in to limit wheel spin across the drive axle. It achieves this by allowing the axle shafts to spin at different speeds while continuously attempting to balance the distribution of torque between the two axles. Consequently, power is transferred to the wheel that has the best traction, thereby improving grip, control, and overall predictability of the vehicle.
