The OS 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 our 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.
OS Giken Super Lock Differentials do not require any “break-in”. We only recommend that after installation and initial fluid fill to drive the vehicle for 1000 miles or 1 hr of track time and then change differential fluid. Please do not dyno the vehicle while on the initial fill.
