What is a 1.5-way limited slip differential?

A 1.5-way LSD locks up during acceleration to send power to both wheels, and it also provides a degree of lock during deceleration. This offers a more stable feel during cornering compared to a 2-way LSD, which locks on both acceleration and deceleration.

What type of gear oil should I use with this Cusco LSD?

It is crucial to use the specific gear oil recommended by Cusco for this differential. Using the incorrect fluid can prevent the LSD from operating correctly and may damage the unit.

Does this differential come with all necessary installation hardware?

This listing is for the Cusco LSD unit itself. It is recommended to replace differential bearings and seals during installation, and these are typically sold separately.

About this part

Product Details

If you're looking to get more grip and better handling out of your performance car, this Cusco RS Limited Slip Differential (LSD) is a solid choice. It's designed to fit a range of popular sports cars and compacts, including the Lotus Elise and Exige, Toyota Celica and MR2 Spyder, and even the Pontiac Vibe and Toyota Matrix. This isn't just about putting power down; it's about making your car feel more connected and predictable when you're pushing it.

The RS model from Cusco is a well-built unit that offers a 1.5-way locking action. What that means in practice is that it locks up during acceleration to send power to both wheels, but it also offers a degree of lock on deceleration. This provides a more stable feel during cornering and helps prevent wheelspin, especially when you're accelerating out of a turn. The internal components are made from durable materials, and the unit is designed for a direct fit into the factory differential housing, making installation more straightforward. You'll notice improved traction, especially when one wheel might lose grip, and a more responsive feel from the drivetrain.

When installing a differential like this, it's important to use the correct gear oil specified by Cusco. This ensures the LSD operates as intended and lasts for a long time. You'll also want to make sure you have a good set of bearings and seals to go along with it, as these are often replaced during a differential service. This Cusco LSD is a significant upgrade for anyone serious about improving their vehicle's performance and handling characteristics.
