OS Giken Ford 9in 31 Spline Rear End LSD (Requires Consultation for Custom Tune)

The OS Giken Super Lock LSD uses their patented pressure ring design for smooth, progressive locking. It accommodates more friction plates than competitors due to its spline-through-side-gear design. All components are chemically heat-treated, constructed from high-grade steel alloy, and gears are raw-forged for maximum strength. Clutch disks are precision-machined for minimal warpage, and the LSD case is machined from a single billet piece. The standard spec allows for low preload while retaining 100% lock capability, offering quiet operation and smooth, predictable locking. This LSD significantly improves the driving experience while maintaining everyday drivability.
