The OS Giken Super Lock LSD is the culmination of over four years of extensive research and development that led to a revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total). Combined with a patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it suitable for both street and racing performance
