The OS Giken Super Lock limited-slip differential for Toyota Corolla AE86 manual-transmission models covers May 1983–September 1985 production. This mechanical LSD moderates torque transfer between driven wheels to improve traction during cornering and when accelerating under load. Specified for those AE86 build dates, the Super Lock unit is intended for owners seeking firmer traction control matched to the original production period.
