What is the main benefit of a 1-way LSD like this Cusco unit?

A 1-way LSD primarily locks the differential under acceleration. This means it helps put power down more effectively when you're on the throttle, reducing wheel spin and improving traction out of corners. It's designed to enhance your car's performance during acceleration-focused driving.

What type of fluid should I use with this Cusco LSD?

Using the correct differential fluid is crucial for the proper function and longevity of your LSD. It is highly recommended to consult the Cusco installation manual or a qualified mechanic for the specific type and viscosity of fluid recommended for this Type-MZ differential.

Does this LSD come with all the necessary installation hardware?

Typically, LSD units are sold as the differential assembly itself. It is common that installation hardware, such as bearings or seals, may need to be purchased separately or reused from the original differential if they are in good condition. Always check the product listing or consult with us to confirm what is included.

About this part

Product Details

If you're looking to get the most out of your Mitsubishi Evo's performance on the track or during spirited driving, a limited-slip differential (LSD) is a critical component. This Cusco Type-MZ 1-way LSD is specifically designed for the rear of Mitsubishi Evo models 1 through 10 that do not have Active Yaw Control (AYC). It works by mechanically limiting the speed difference between the rear wheels, which helps put power down more effectively, especially when exiting corners. This means less wheel spin and more forward acceleration, giving you a noticeable improvement in grip and control.

The Type-MZ series from Cusco is well-known for its smooth engagement and predictable operation. This 1-way version is set up to primarily lock under acceleration, providing a strong bias towards improving traction when you're on the throttle. The internal cone clutch design is durable and offers a good balance between performance and streetability. Cusco has engineered this unit with specific ramp angles (PPEF 55/0 & 55/55) to offer a unique torque-sensing characteristic that helps manage power delivery precisely. It's a solid option for Evo owners who demand more from their drivetrain.

Installing a limited-slip differential is a significant upgrade that requires careful attention to detail. It's recommended to have this unit installed by a qualified mechanic who is familiar with differential work. You'll also need to ensure you have the correct differential fluid, as using the wrong type can affect performance and longevity. This Cusco LSD is a well-built component designed to handle the demands of performance driving, offering a substantial improvement in how your Evo puts its power to the ground.
