What is a 2-way limited slip differential?

A 2-way limited slip differential (LSD) engages to provide traction not only when you are accelerating but also when you are decelerating. This helps to keep both rear wheels turning together during cornering, improving stability and control.

What is the difference between this and a 1-way or 1.5-way LSD?

A 1-way LSD primarily engages during acceleration. A 1.5-way LSD engages during acceleration and partially during deceleration. The 2-way design offers engagement in both directions, providing a more consistent feel during spirited driving and cornering.

What type of fluid should I use with this differential?

Refer to the manufacturer's installation instructions for the specific differential fluid type and viscosity recommended by Cusco for this LSD. Using the correct fluid is crucial for proper operation and longevity.

About this part

Product Details

Cusco is well-known for making performance parts that help drivers get the most out of their vehicles, especially Subarus. This RS-2way limited slip differential (LSD) is designed specifically for the 2004-2007 Subaru Impreza, giving you improved traction and handling for spirited driving or track use. It's a well-built unit that can make a notable difference in how your car puts power down, especially when cornering.

This particular LSD is a 2-way type, meaning it engages both during acceleration and deceleration. This offers a more consistent feel and helps manage the car's rotation when you lift off the throttle mid-corner. The RS designation indicates a specific internal design that balances aggressive locking action with smoother engagement, making it a popular choice for drivers who want a significant performance upgrade without sacrificing too much daily drivability. It's built with durable materials to handle the stresses of performance driving, ensuring it holds up over time.

When installing a differential like this, it's important to follow the manufacturer's instructions carefully, as it involves working with the drivetrain. You'll typically need to drain and refill the differential fluid with a specific type recommended by Cusco. This LSD is designed to fit directly into the rear end of your 2004-2007 Impreza, replacing the factory open differential.
