What is a Limited Slip Differential (LSD) and why would I want one?

A Limited Slip Differential (LSD) is a type of differential that allows for some variation in wheel speed while still transmitting torque to both drive wheels. This is beneficial for performance driving as it helps prevent wheelspin during acceleration, especially when cornering or on uneven surfaces, leading to improved traction and control.

Can this OS Giken LSD be adjusted for different driving conditions?

Yes, the OS Giken Super Lock LSD features an adjustable lock-up percentage. This allows you to fine-tune how much torque is sent to each wheel, enabling you to customize the differential's behavior to match your driving style and the specific conditions you'll be encountering.

What is included with the OS Giken Super Lock LSD?

The OS Giken Super Lock LSD is a complete differential unit. It is designed to replace your vehicle's factory differential. It is recommended to consult the manufacturer's installation guide for a full list of components and any additional hardware or fluids that may be required for installation.

Product Details

OS Giken is well-known for making high-performance drivetrain components, and their Super Lock Limited Slip Differential (LSD) is a prime example of that expertise. If you're looking to significantly improve the traction and handling of your 1990-1997 or 1999-2005 Mazda Miata with a manual transmission, this LSD is a serious upgrade. It's designed to put power down more effectively, especially when you're accelerating out of corners or dealing with uneven road surfaces.

The Super Lock LSD uses a unique multi-plate design that allows for a very high initial lock-up percentage, which can be adjusted to suit your driving style and track conditions. This means that even under hard acceleration, both rear wheels receive torque, helping to prevent wheelspin and keep your car moving forward. The advanced internal mechanism is built to handle the stresses of performance driving, offering a solid and reliable way to enhance your vehicle's performance. Installation involves replacing the entire differential unit, so it's a job that requires some mechanical know-how and the right tools.

This unit is specifically designed for manual transmission models of the Miata and also fits the FC3S RX-7 NA manual transmission. When you're pushing your car hard, having a differential that can manage power distribution effectively makes a noticeable difference in control and confidence. This OS Giken LSD is a well-built component that can help you get the most out of your Miata's chassis.
