What is a limited-slip differential (LSD) and how does it work?

A limited-slip differential (LSD) is a type of differential that allows for some difference in rotational speed between the left and right wheels, while still limiting the speed difference. This helps improve traction, especially when accelerating or cornering, by ensuring both wheels receive power more evenly.

What is the break-in procedure for this OS Giken LSD?

OS Giken typically recommends a specific break-in procedure for their clutch-type LSDs to ensure proper seating of the clutch plates. It's crucial to refer to the manufacturer's installation manual for the exact steps, which usually involve a period of gentle driving with specific acceleration and deceleration cycles.

What else might I need to install this LSD?

Installing an LSD often requires specialized tools and knowledge. You may need new differential fluid, seals, and potentially a gear set if you are changing the final drive ratio. It is highly recommended to have this component installed by a professional mechanic experienced with performance drivetrain work.

About this part

Product Details

OS Giken is well-known for making high-performance drivetrain components, especially their clutch-type limited-slip differentials. This Super Lock LSD is designed specifically for Alfa Romeo models with 1300, 1600, or 1750cc engines equipped with a manual transmission. If you're looking to improve traction and handling on your classic Alfa, this differential is a serious upgrade.

The Super Lock LSD uses a unique multi-plate design that offers a very strong locking effect. This means that when you're accelerating out of a corner, both rear wheels receive power more evenly, which helps prevent wheelspin and improves stability. Unlike some other LSDs that can feel grabby or unpredictable in daily driving, OS Giken's design aims for a smooth engagement that still provides maximum performance when you need it. The F105 designation refers to the specific housing and gear set compatibility for these Alfa Romeo transmissions.

Installing a limited-slip differential is a significant modification that can really change how your car feels and performs. It's a job that requires careful attention to detail and proper setup to ensure it works correctly and lasts. While this LSD is built to be robust, it's important to follow the manufacturer's recommended break-in procedure and maintenance schedule to get the most out of it. This unit is designed for manual transmission applications only.
