OS Giken Porsche Boxster S (2nd Gen / MT Only) / Cayman (MT Only) Super Lock LSD

OS Giken Porsche Boxster S (2nd Gen / MT Only) / Cayman (MT Only) Super Lock LSD

Upgrade the traction and handling of your Porsche with the OS Giken Super Lock Limited Slip Differential, Part Number osgPR151-HA. Designed for select second-generation Porsche Boxster S and Cayman models equipped with a manual transmission, this differential helps distribute power more effectively between the drive wheels during acceleration, cornering, and changing grip conditions. Its application-specific design supports a direct fit for compatible factory drivetrains without requiring an automatic transmission configuration.
The OS Giken Super Lock LSD is engineered for performance-focused driving where predictable power delivery and improved corner-exit traction are essential. By limiting unwanted wheel spin, it can help the vehicle maintain forward momentum when one driven wheel loses grip. The result is more consistent handling characteristics and improved driver control on the street, at the track, or during spirited driving. OS Giken is recognized for developing high-performance drivetrain components designed to withstand demanding use while maintaining precise operation.
Compatibility should be confirmed before installation. This LSD is intended for manual-transmission applications only and fits select Porsche Boxster S and Cayman vehicles, including applicable 2009 and 2012 model-year configurations. Verify the vehicle model, year, transmission, differential specification, and final-drive setup against the manufacturer’s application data. Professional installation is recommended to ensure proper setup, bearing condition, gear engagement, and differential preload. The package includes one OS Giken Super Lock LSD assembly identified by Part Number osgPR151-HA.
