  2. Normal Differential • On every car a basic differential is fitted to to distribute the engine's power to the driving wheels.

  3. Formal Definition A Limited Slip Differential (LSD) is a modified or derived type of differential gear arrangement that reduces wheel spin, especially when cornering at high speed by allowing for some difference in rotational velocity of the output shafts. Limited Slip Differential (LSD) does not allow the difference in speed to increase beyond a preset amount. By limiting the velocity difference between the pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.

  4. 1-Way, 2-Way, 1.5-Way

  5. Summary The Limited Slip Differential (LSD) reduces wheel spin while cornering at high speeds to maintain: • Go-kart like handling. • Optimum traction between tires and pavement.
