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

A 2-way LSD actively manages torque distribution to both rear wheels during acceleration and deceleration. This improves traction and stability, especially when cornering aggressively, by ensuring both wheels are driven even when one might otherwise lose grip.

Can I adjust the engagement of this differential?

Yes, this Cusco MZ series differential allows you to adjust its engagement characteristics between 1.5-way and 2-way settings. This lets you fine-tune how the differential behaves to match your driving style and the conditions you're driving in.

What type of fluid should I use with this differential?

For optimal performance and longevity, it is recommended to use specific LSD oil as recommended by Cusco. Using the correct fluid ensures the clutch plates engage smoothly and are protected from excessive wear.

About this part

Product Details

Forged from high-carbon steel, this Cusco LSD (Limited Slip Differential) is built for serious performance driving. It's designed to replace your factory open differential with a unit that can actively manage torque distribution between your rear wheels. This means when you're accelerating out of a corner, both wheels will receive power, improving traction and reducing the tendency for one wheel to spin uselessly. The 'MZ' series is Cusco's well-known line of clutch-type LSDs, offering a noticeable improvement in handling dynamics for performance-oriented vehicles.

This particular unit offers a unique 2-way activation, meaning it engages not only during acceleration but also during deceleration. This provides consistent control and stability under both conditions, which is especially beneficial during aggressive driving or track use. You can also adjust the engagement characteristics between 1.5-way and 2-way settings, allowing you to fine-tune how the differential behaves based on your driving style and track conditions. The clutch plates are made from a durable, high-friction material designed to withstand the heat and stress of spirited driving, ensuring reliable performance over time. Installation involves replacing the entire differential unit, so professional installation is recommended to ensure proper setup and alignment.

When installing a clutch-type LSD like this, it's important to use the correct differential fluid. Cusco recommends specific LSD oil to ensure the clutch plates engage smoothly and last as long as possible. Proper break-in procedures, as outlined by Cusco, are also crucial for the longevity of the unit. This differential is a significant upgrade for anyone looking to maximize the performance and handling of their vehicle on the track or during spirited road driving.
