What is the main benefit of a 2-way limited-slip differential?

A 2-way limited-slip differential (LSD) improves traction by mechanically limiting the speed difference between the wheels during both acceleration and deceleration. This means both wheels receive power more consistently, reducing wheel spin and enhancing grip during cornering and in slippery conditions.

What type of fluid should I use with the Cusco Type RS LSD?

It is crucial to use the specific differential fluid recommended by Cusco for the Type RS LSD. Using the incorrect fluid can affect performance and potentially damage the unit. Always refer to the manufacturer's installation guide for the exact fluid specifications.

Is this LSD a direct bolt-on replacement for the factory differential?

While this LSD is designed to fit the specified 93-98 Mazda Miata NA8 manual transmission, installation typically requires specialized tools and mechanical expertise. It is not a simple bolt-on job and often involves removing the differential housing and potentially modifying or replacing other drivetrain components. Consulting a professional mechanic is recommended.

About this part

Product Details

The Cusco Type RS 2-way limited-slip differential (LSD) uses a unique cone clutch system, a design choice that allows for smooth engagement and a predictable feel during both acceleration and deceleration. This particular unit is built for the 93-98 Mazda Miata NA8 manual transmission, offering a significant upgrade over the factory open differential. By mechanically limiting wheel speed difference, it ensures that both rear wheels receive power, dramatically improving traction during spirited driving, cornering, and even in slippery conditions. This means less wheel spin and more forward momentum when you need it most.

Cusco's Type RS design is known for its ability to provide a strong locking effect under acceleration while still allowing for a degree of differential action during deceleration, making it a versatile choice for a wide range of driving situations. The cone clutch mechanism is designed for durability and consistent performance, and it's a popular option for Miata owners looking to enhance their car's handling and performance. Installation involves replacing the factory differential, and it's a job that requires specialized tools and knowledge, so we always recommend consulting a professional mechanic or referring to the manufacturer's detailed installation instructions.

When installing this LSD, it's important to use the correct differential fluid as specified by Cusco to ensure optimal performance and longevity of the unit. This differential is designed to work with the factory transmission and driveshafts for the specified Miata models, but always double-check your vehicle's specific configuration. The result is a more connected and responsive driving experience, allowing you to put the power down more effectively and confidently navigate challenging turns.
