Cusco (Non) LSD Type MZ 1.5way Rear Mazda RX-7 FC3S/FD3S / RX-8 SE3P

This is the Cusco Type MZ 1.5-way limited-slip differential (LSD) for your 1986-1995 Mazda RX-7 (FC3S and FD3S chassis) and 2004-2011 Mazda RX-8. An LSD is a crucial component for performance driving, especially in rear-wheel-drive cars like the RX-7 and RX-8. It helps distribute power more evenly between the rear wheels, improving traction during acceleration out of corners and enhancing overall stability and control.

The Type MZ is a clutch-type LSD, known for its smooth engagement and predictable operation. The 1.5-way design means it applies locking force not only during acceleration but also partially during deceleration. This provides a unique balance: it helps pull the car through a corner under power and offers a degree of stability when you lift off the throttle, without being overly intrusive. This makes it a popular choice for drivers who want improved performance on both the street and the track. Cusco uses well-built internal components designed for durability and consistent performance over time.

When installing an LSD, it's important to use the correct differential fluid, often a specialized gear oil with friction modifiers designed for limited-slip units. Refer to the manufacturer's installation instructions for specific fluid recommendations and any break-in procedures. This unit is designed to fit directly into the factory differential housing, simplifying the installation process for a qualified mechanic.
