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

A 1-way LSD primarily locks the differential under acceleration, helping to put power down. A 2-way LSD locks under both acceleration and deceleration, which can aid in cornering stability and predictability by helping to keep the rear end planted.

What type of fluid should I use with this LSD?

It is crucial to use the specific differential fluid recommended by Cusco for this Type RS LSD. Using the incorrect fluid can affect performance and may require a specific break-in procedure.

Does this LSD come with all necessary installation hardware?

This product is the differential unit itself. Installation typically requires reusing some factory hardware and may require additional seals or gaskets. Always refer to the manufacturer's installation instructions for a complete list of required parts and procedures.

About this part

Product Details

Cusco is well-known for making solid drivetrain components, and their Type RS Limited Slip Differential (LSD) for the 2009-2014 Nissan 370Z is a prime example. If you're looking to put power down more effectively, especially when exiting corners or accelerating hard, an LSD is a key upgrade. This unit helps manage power distribution between your rear wheels, reducing wheelspin and improving traction. It's designed to work with the factory automatic transmission (AT) rear end.

The Type RS features a unique clutch-type mechanism that offers a good balance between aggressive locking action and smooth engagement. It's built with durable materials to handle the stresses of spirited driving. Cusco offers this differential in either a 1-way or 2-way configuration, allowing you to tailor its behavior to your driving style. A 1-way LSD primarily locks under acceleration, while a 2-way locks under both acceleration and deceleration. This helps improve stability and predictability during cornering. Installation involves removing the factory differential and replacing it with this unit, so it's a job best suited for a shop with experience in differential work.

When installing this LSD, it's important to use the correct differential fluid recommended by Cusco to ensure proper break-in and long-term performance. This upgrade can significantly change how your 370Z handles, providing a more connected feel to the road and allowing you to apply throttle earlier and with more confidence. Make sure to consult the manufacturer's installation instructions for specific details regarding fluid types and break-in procedures.
