Description

Part #: HA111-HA2

MIA's Description

The OS Giken Super Lock LSD uses a patented pressure ring for smooth, progressive locking. It features a spline-through-side-gear design, allowing for up to twice as many friction plates as competitors. All components are chemically heat-treated for maximum durability and constructed from high-grade steel alloy. Gears are raw-forged for maximum strength, and clutch disks are precision-machined to tight tolerances, minimizing warpage. The LSD case is machined from a single billet piece, ensuring uniformity. The standard OS LSD specification allows for low preload while retaining 100% lock capability. It operates quietly, and the progressive locking provides smooth, predictable engagement, significantly improving the driving experience and maintaining everyday drivability when replacing an open differential.
