What is the difference between 1.5-way and 2-way LSD action?

A 2-way LSD locks during both acceleration and deceleration. A 1.5-way LSD locks strongly during acceleration and lightly during deceleration, offering a balance between grip and smoother cornering. This Cusco RS model offers both options, selectable via its internal cam design.

What type of gear oil should I use with this differential?

It is crucial to use the correct gear oil for limited-slip differentials, as standard gear oil may not contain the necessary friction modifiers. Always refer to the Cusco installation manual or contact their support for the specific recommended fluid type and viscosity to ensure optimal performance and longevity.

Does this differential come with all necessary installation hardware?

This product includes the differential unit itself. However, installation typically requires additional components such as new bearings, seals, and potentially specialized installation tools. It is recommended to consult the manufacturer's installation guide or a professional mechanic to determine all necessary parts and tools for a complete and proper installation.

About this part

Product Details

The Cusco LSD RS 2 Way(1.5&2) differential utilizes a unique cam mechanism that allows for both 1.5-way and 2-way locking action, depending on the driving situation. This advanced design means it engages strongly during acceleration and deceleration, providing a more connected feel between the wheels. For drivers looking to improve traction and handling, especially during spirited driving or on track, a limited-slip differential like this can make a notable difference.

This differential is built with precision and durability in mind, featuring a well-built internal mechanism designed to handle the stresses of performance driving. The RS model specifically incorporates features aimed at reducing chatter during low-speed turns, offering a more refined experience compared to some other performance differentials. Installation involves replacing the factory open or limited-slip differential, requiring specialized tools and knowledge of drivetrain components. It's a significant upgrade for those seeking to maximize grip and control from their vehicle's drivetrain.

When installing this differential, it's important to follow the manufacturer's break-in procedure carefully to ensure the longevity of the clutch plates and other internal components. This typically involves a period of gentle driving followed by a fluid change. Proper gear oil is also crucial for the performance and lifespan of the LSD, so be sure to use a fluid recommended by Cusco or one that meets the specific requirements for this type of differential.
