What is a 1.5-way LSD and how does it differ from a 2-way?

A 1.5-way LSD locks strongly during acceleration and partially locks during deceleration. This helps stabilize the car during corner entry. A 2-way LSD locks equally during both acceleration and deceleration, which can be more aggressive and sometimes less predictable for street use.

What is included with the Cusco LSD Type MZ?

This kit includes the Cusco Type MZ 1.5-way LSD unit. It is designed to work with your factory differential housing, but typically requires additional components like new bearings, seals, and differential fluid for a complete installation. Refer to Cusco's installation guide for a full list of recommended parts.

What kind of maintenance does this LSD require?

Proper maintenance involves using the correct differential fluid specified by Cusco and following their recommended break-in procedure. Regular fluid changes according to your driving conditions will help ensure the longevity and performance of the clutch plates within the LSD.

About this part

Product Details

This is the Cusco Type MZ 1.5-way limited-slip differential (LSD) specifically for the Mazda RX-7 FC3S. If you're looking to significantly improve your RX-7's traction and handling, especially during spirited driving or track use, an LSD is a critical component. It helps distribute power more evenly between the rear wheels, reducing wheelspin and allowing you to put power down more effectively out of corners.

The Type MZ is a clutch-type LSD, known for its strong locking force and smooth engagement. This 1.5-way design means it locks up strongly during acceleration, providing excellent traction, and partially locks during deceleration, which helps stabilize the rear end during corner entry. This balance is often preferred for performance driving as it offers a predictable feel. Cusco is well-known for its high-performance drivetrain components, and this LSD is built with robust materials to handle the demands of a performance RX-7. It's designed to work with the factory differential housing, making installation more straightforward compared to a full aftermarket housing. You'll notice a significant difference in how the car accelerates out of turns, with less inside wheel spin and more planted feel.

When installing this LSD, it's important to use the correct differential fluid and break-in procedure as recommended by Cusco. This ensures the clutch plates bed in properly and the LSD performs optimally for its lifespan. This unit is designed to replace your factory open or limited-slip differential, so ensure you have the necessary tools and knowledge for a differential rebuild, or consider professional installation to ensure it's set up correctly.
