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

A 1-way LSD primarily engages during acceleration to improve traction. A 2-way LSD, like this Cusco RS model, engages during both acceleration and deceleration. This provides enhanced stability and control during cornering, both when applying throttle and when lifting off.

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

It is crucial to use the specific gear oil recommended by Cusco for this RS-2way differential. Using the incorrect fluid can impact performance and potentially damage the LSD. Always refer to the manufacturer's installation guide or contact Cusco for their specific fluid recommendations.

Does this limited slip differential come with all necessary installation hardware?

This product listing is for the Cusco RS-2way rear limited slip differential unit itself. It is recommended to consult the manufacturer's installation instructions or contact Cusco directly to confirm if any specific installation hardware or seals are included, or if they need to be sourced separately.

About this part

Product Details

This Cusco RS-2way rear limited slip differential (LSD) is designed specifically for your 2004-2007 Subaru Impreza. You'll receive the differential unit itself, ready for installation. This part is a significant upgrade for drivers looking to enhance their vehicle's traction and cornering performance, especially during spirited driving or track use. It works by actively distributing torque between the rear wheels, helping to prevent wheelspin and improve the car's ability to put power down through turns.

The RS-2way design offers a unique balance of performance characteristics. It engages on both acceleration and deceleration, meaning it helps control the car's attitude when you're on the throttle and also provides stability when you lift off. This dual action can lead to a more predictable and confidence-inspiring feel when pushing the limits. Cusco is well-known for its performance drivetrain components, and this LSD is built to handle the demands of performance driving. Proper installation by a qualified mechanic is recommended, as it involves working with the rear differential and drivetrain components.

When upgrading your differential, it's important to consider other drivetrain fluids. Ensure you use the correct gear oil specified by Cusco for this LSD to maintain its performance and longevity. This differential is a substantial modification that can change how your Impreza handles, offering a more connected and responsive driving experience.
