What is a 1.5-way limited-slip differential?

A 1.5-way LSD engages more aggressively during acceleration than during deceleration. This means it locks up strongly when you're applying throttle, helping to put power down, but unlocks more freely when you lift off the gas or brake, making the car feel more predictable.

What type of fluid should I use with this LSD?

It is crucial to use the specific differential fluid recommended by Cusco for this Type MZ LSD. Using the correct fluid ensures proper operation of the clutch plates and helps maintain the longevity of the differential.

What else might I need for installation?

Installation of a rear differential typically requires specialized tools and knowledge. You will likely need to drain and refill the differential with the correct fluid, and it's recommended to consult a professional mechanic or refer to the manufacturer's installation guide for specific procedures and any additional hardware or seals that may be required.

About this part

Product Details

The Cusco Type MZ 1.5-way limited-slip differential is built with a unique clutch plate design that offers a distinct advantage for performance driving, especially in a car like the GR Yaris. This differential uses a specific cam angle that allows for a 1.5-way engagement. What this means in practice is that it locks up more aggressively during acceleration than during deceleration. This provides a strong, stable platform when you're powering out of a corner, helping to put the power down more effectively. When you lift off the throttle or brake, it unlocks more freely, which can make the car feel more predictable and easier to manage during spirited driving or track use.

Cusco has a long history with performance drivetrain components, and the Type MZ is a popular choice for enthusiasts looking to improve their car's handling. The internal components are well-made, designed to handle the stresses of hard driving. This unit is specifically designed to fit the 2021 and newer Toyota GR Yaris, ensuring it integrates properly with your existing drivetrain. Installation will involve removing the rear differential and replacing the factory unit with this performance-oriented LSD. It's a significant upgrade that changes how the car puts power down, offering improved traction and a more connected feel to the road.

When installing a limited-slip differential, it's important to use the correct differential fluid as recommended by Cusco. This ensures the clutch plates operate as intended and helps prolong the life of the unit. This LSD is a substantial upgrade for GR Yaris owners looking to maximize their car's performance potential, especially for track days or autocross events where precise power delivery is key.
