For our die-hard customers running our Getrag Differential Upgrade Kit, OS Giken has finally released an upgraded differential for the G80 Getrag differential.

The stock LSD in the G80 struggles with high horsepower on the track, factory units are hard to find with ideal ratios, and aftermarket options were previously nonexistent.

This new LSD fits both LSD and non-LSD diffs, making it easier to find a diff with your desired ratio and upgrade it with OS Giken’s superior unit. This means you no longer need to scour the earth for a LSD unit and pay top dollar. This opens all sorts of possibilities with lower cost G80 differential purchases.

Key Features:

• Smooth lock timing: transitions seamlessly from normal differential to 100% lock under full power, thanks to advanced gear-driven technology.
• True 100% lock: features more clutch disks than any other differential, ensuring sustained lockup even under high horsepower.
• Durable design: forged housing minimizes heat and spreads load for consistent performance and reliability.
• Improved handling: patented pressure control ring reduces understeer by unlocking instantly off-throttle for faster corner entry.
• Enhanced traction: re-locks immediately during corner exit, maximizing grip and minimizing wheel spin.

Special notes:

• You MUST run OS Giken gear oil (1 quart)
• Change fluid once per season
