What is the advantage of a limited-slip differential (LSD) over an open differential?

An open differential sends power to the wheel with the least resistance, often leading to wheelspin. An LSD, like this OS Giken Super Lock, distributes power more evenly between both wheels, improving traction especially during acceleration and cornering.

What type of gear oil should I use with this OS Giken LSD?

It is crucial to use the specific gear oil recommended by OS Giken for this Super Lock LSD. Using the incorrect oil can affect performance and potentially damage the unit. Refer to the manufacturer's installation guide for the exact specifications.

Does this differential come with all necessary installation hardware?

This listing is for the OS Giken Super Lock LSD unit itself. Installation typically requires additional components such as bearings, seals, and potentially a new ring gear if you are changing the gear ratio. It is recommended to consult the installation manual or a professional mechanic for a complete parts list.

About this part

Product Details

If you're looking to get the most out of your classic Porsche 911 or 914 on the track or during spirited driving, a limited-slip differential (LSD) is a crucial upgrade. This OS Giken Super Lock LSD is specifically designed to improve traction and handling for your narrow-body 911 from 1969-1971 and your 914 from 1970-1976. It helps put power down more evenly to both rear wheels, reducing wheelspin and allowing for faster acceleration out of corners.

OS Giken is well-known for its robust and high-performance drivetrain components, and this Super Lock LSD is no exception. It utilizes an advanced multi-plate design that offers a very strong locking effect, which can be adjusted to suit your driving style and track conditions. The internal components are made from strong, durable materials, built to withstand the rigors of performance driving. This unit is designed as a narrow-case differential, meaning it's intended to fit the specific differential housing found in these Porsche models without extensive modification to the housing itself. Proper installation will involve setting backlash and gear mesh correctly, which is critical for smooth operation and longevity.

When installing a new differential, it's important to use the correct gear oil specified by OS Giken to ensure optimal performance and durability. This LSD is a significant upgrade for any enthusiast looking to enhance their classic Porsche's performance and handling capabilities. It's a well-built component that can make a noticeable difference in how your car puts power down and corners.
