Frequently Asked Questions
What makes OS Giken LSDs different from Cusco or Quaife?
OS Giken Super Lock LSDs use a multi-plate clutch design with extremely precise tolerances — hand-assembled in Japan with consistent ramp angle and clutch pack specifications. They are at the highest tier of LSD quality available. Cusco and Quaife are also excellent but OS Giken is considered the absolute premium for Japanese platform differentials by serious enthusiasts and professional teams.
Do OS Giken LSDs require special differential oil?
Yes — OS Giken specifies dedicated LSD oil for their clutch-type differentials. Using standard gear oil causes clutch pack wear and chatter. Use OS Giken's specified LSD fluid or an LSD-rated gear oil at each service interval.
