Its performance directly impacts acceleration, stability, and how effectively a car puts power to the ground. OS Giken differentials are renowned for their durability and advanced design, providing smooth yet aggressive torque transfer for maximum traction. With an OS Giken LSD, drivers gain improved cornering balance, consistency under load, and the reliability needed for both street and competition use.
