Cusco LSD 1C8 B15 Type MZ Limited Slip Differential 1.5-Way Rear

The Cusco Type MZ Limited Slip Differential is engineered for high-performance applications where smooth torque delivery and maximum traction are essential. This rear differential is designed specifically for 2021+ Toyota GR Yaris models and features a 1.5-way configuration optimized for both acceleration and deceleration control.

Type MZ Technology:

The Type MZ utilizes advanced cone plate (belleville spring) technology that creates higher initial torque compared to Cusco's Type RS differentials. This design produces activation pressure that opposes the direction of initial torque, resulting in more aggressive locking characteristics and superior traction on low-grip surfaces. The cone spring delivers high initial torque with linear clutch pack engagement, making it ideal for race and track applications.

Key Features:

• 1.5-way configuration provides differential locking during acceleration with reduced locking on deceleration
• Cone plate technology delivers higher initial torque than Type RS models
• High-tensile forged chromoly construction for side gears, pinion gears, and case
• Oil-through system design ensures optimal cooling and lubrication
• Adjustable cam specifications allow fine-tuning for different race applications
• Superior forward traction and stability on loose or low-traction surfaces
• Engineered for high-horsepower applications with track-focused durability

1.5-Way Operation:

The 1.5-way design activates under acceleration while providing reduced understeer compared to 2-way differentials. It limits slip during both acceleration and deceleration, though unevenly in each direction, allowing for effective engine braking while maintaining balanced handling characteristics preferred by competitive racers.

Application Note:

This rear differential is specifically designed for 2021+ Toyota GR Yaris (GXPA16) models. Professional installation and proper LSD-specific gear oil are required for optimal performance and longevity. The Type MZ is best suited for track, competition, and racing applications where maximum traction and high initial torque are beneficial.
