What is the main benefit of a 1-way limited-slip differential?

A 1-way LSD primarily locks under acceleration, which helps put power down more effectively and reduces wheel spin. This improves traction when you're accelerating out of corners or off the line. The locking effect disengages when you lift off the throttle, allowing for more predictable handling during corner entry.

Does this differential come with all necessary installation hardware?

Typically, specialized drivetrain components like LSDs require specific installation hardware and fluids. It is recommended to consult the manufacturer's installation manual or contact a professional mechanic to confirm exactly what is included and what additional parts or fluids are needed for proper installation.

How does the adjustable initial torque affect performance?

The initial torque setting, ranging from 3kg to 5kg in this Cusco RS differential, determines how much locking force is applied when there's no acceleration or deceleration. A higher initial torque can lead to more aggressive locking and improved traction in certain situations, while a lower setting can offer smoother engagement. This adjustability allows for fine-tuning to match your driving style and track conditions.

About this part

Product Details

The Cusco RS 1-way limited-slip differential (LSD) is built with a unique clutch pack design, featuring a PPHB 35/0 and 45/0 clutch configuration. This setup allows for an initial torque setting between 3kg and 5kg, which is crucial for how the differential behaves during acceleration and deceleration. For your Mitsubishi Lancer Evolution VIII or IX (CT9A) equipped with the Active Center Differential (ACD) and a 5-speed manual transmission, this front LSD is designed to significantly enhance traction and handling characteristics, especially during spirited driving and track use.

This 1-way design means the differential locks under acceleration, helping to put power down more effectively and reduce wheel spin. When you lift off the throttle, the locking effect disengages, allowing for more predictable handling during corner entry. The RS series from Cusco is known for its smooth engagement and consistent performance, making it a popular choice for drivers looking to improve their vehicle's cornering ability and overall grip. The initial torque setting is adjustable, allowing for fine-tuning to suit your driving style and track conditions. This differential is a substantial upgrade for the Evo's drivetrain, providing a more connected feel and improved control when you need it most.

Installing a front LSD like this is a significant modification that changes how your car puts power down. It's often paired with other drivetrain upgrades to create a balanced performance package. Ensure you consult with a professional mechanic or refer to Cusco's installation manual for proper fitment and setup procedures, as this is a complex component to install. The ACD system on your Evo requires specific considerations during installation, so professional service is highly recommended to ensure optimal performance and longevity of both the differential and your vehicle's systems.
