Cusco LSD RS-Rear 1.5way CT9A EVO8 w/AYC Side BEARing NOT inCLUDED

This Cusco RS-Rear 1.5-way limited-slip differential (LSD) is designed specifically for the 2003-2005 Mitsubishi Lancer, including models equipped with AYC (Active Yaw Control). When you're pushing your Lancer hard, especially through corners or during spirited driving, a standard open differential can let one wheel spin while the other does all the work. This Cusco LSD changes that by actively distributing torque between the rear wheels, ensuring both have grip. This means improved acceleration out of turns and more stable handling under load.

The RS model from Cusco is known for its smooth engagement and predictable operation, making it a solid choice for drivers who want a noticeable improvement in their car's performance without sacrificing daily drivability. Its 1.5-way design means it applies locking force not only during acceleration but also partially during deceleration, which helps to stabilize the rear end during cornering and braking. This particular unit is built for the CT9A chassis code, commonly associated with the Evo 8, and is designed to work with the AYC system, though it's important to note that the side bearings are not included and will need to be sourced separately. This ensures that when you install it, you're getting a well-built component that directly addresses the need for better traction and control in your Lancer.

Installing an LSD is a significant upgrade for your drivetrain, and the Cusco RS model offers a refined performance experience. Because this is a major drivetrain component, it's recommended to have it installed by a qualified mechanic who is familiar with differential work and AYC systems. Ensure you have all necessary ancillary parts, such as the side bearings, ready before beginning the installation process to minimize downtime.
