What is the difference between a 1-way and a 2-way LSD?

A 1-way LSD primarily engages during acceleration, helping to distribute power to both wheels when you're on the throttle. A 2-way LSD, like this Cusco Type MZ, engages during both acceleration and deceleration (engine braking). This provides more consistent traction and stability during cornering and when lifting off the throttle.

What is included with this Cusco LSD?

This product includes the Cusco Type MZ 2-way limited-slip differential unit itself. It is designed to replace your vehicle's existing differential. You will need to source any additional installation hardware or fluids separately, following manufacturer recommendations.

What kind of fluid should I use with this LSD?

It is crucial to use the specific differential fluid recommended by Cusco for the Type MZ LSD. Using the incorrect fluid can affect performance, break-in, and the longevity of the unit. Always refer to the Cusco installation manual or contact their support for the exact fluid specifications.

About this part

Product Details

This Cusco Type MZ 2-way limited-slip differential (LSD) comes with the differential unit itself, ready for installation into your 1986-1995 Mazda RX-7 (FC3S/FD3S) or 2004-2011 Mazda RX-8 (SE3P). This is a significant upgrade for drivers looking to improve traction and handling, especially during spirited driving or track use. The 2-way design means it engages both during acceleration and deceleration, providing consistent power distribution to both rear wheels in a variety of driving conditions. This helps reduce wheel spin and allows for a more predictable and controlled drift or corner exit.

The Type MZ series from Cusco is well-known for its robust construction and reliable performance. It utilizes a multi-plate design with carefully calibrated springs and lock-up settings to offer a noticeable improvement in grip without being overly aggressive for daily driving. The internal components are made from durable materials designed to withstand the stresses of performance driving. Installation involves replacing your factory open or clutch-type differential with this unit, and it's important to use the correct differential fluid recommended by Cusco to ensure proper break-in and long-term operation. This LSD is designed to work with the specific drivetrain configurations of the RX-7 and RX-8 models it fits.

When installing a limited-slip differential, it's always a good idea to consult the manufacturer's installation guide for specific break-in procedures. Proper break-in helps seat the clutch plates correctly, ensuring optimal performance and longevity of the LSD. This Cusco unit is a popular choice for rotary-powered Mazdas looking to put their power down more effectively and enhance the overall driving experience.
