MIA's Description

The OS Giken Super Lock LSD uses a patented pressure ring design for smooth, progressive locking. It features a spline-through-side-gear design allowing for more friction plates. All components are chemically heat-treated high-grade steel alloy, with raw-forged gears. Clutch disks are precision-machined, and the LSD case is machined from a single billet piece. It offers low preload with 100% lock capability, quiet operation, and smooth, predictable locking.
